Plasticizers for benzoate water based adhesives
The compound plasticizer CHUANJUN705 is a plasticizer used for polyfunctional benzoate water based adhesives, which can produce special effects in the polyvinyl acetate adhesive. The benzoate water based adhesives have a special effect in the acrylic latex filling agent with the plasticizer. Benzoate water based adhesives have excellent solubility in plastic sol and dry mixed ethylene with plasticizers.
Benzoic acid ester water-based adhesive plasticizer for environmental protection, safety, adjacent benzene two formic acid ester the best alternatives can be used for food packaging applications; improved adhesive adhesive response, the best volume ratio; reduce the hardening time and prolong the open time; low volatile organic compounds. Low odor, improve the working environment.
Also known as methyl benzoate, benzoic acid methyl ester, the chemical can be regarded as benzoic acid or benzoic anhydride or benzoyl chloride with methanol alcoholysis. Colorless transparent liquid. It can be mixed with methanol, ethanol and ether; it is insoluble in water. It can be used as an organic synthetic intermediate, solvent and spice in industry. With Holly oil and Younanjia oil aroma, flavor and fragrance for the preparation of artificial oil; also used in food.
Refining method: often contains free benzoic acid and methanol and other impurities. When refined, sodium bicarbonate or potassium carbonate solution is used to wash, and the anhydrous potassium carbonate or sodium sulfate is dried after drying.
Benzoic acid and methanol are put into the container, and the sulfuric acid is slowly added to the edge, and the 12h is heated and reacted. After the reaction is finished, the methanol is recovered and then washed. After drying, the finished product is distilled by vacuum distillation.
Methyl benzoate is found in natural lilac oil, Yilan oil and moonlight oil, and can be distilled from essential oils. Industrial production is prepared by the esterification of benzoic acid to methanol in the presence of sulfuric acid. Benzoic acid is mixed with methanol and slowly added to concentrated sulfuric acid. It is heated to about 70 C to return to 4h, and excess methanol is vaporized. Cooling, separating acid liquid, after washing and drying, depressurization distillation, collect 104-105 C (5.2kPa) distillate that is the finished product. The yield is above 90%.
Polyvinyl acetate (polyvinyl acetate), also known as polyvinyl acetate. It is a polymer of vinyl acetate (vinyl acetate). The English abbreviation is PVAc. For short, PVAc, the copolymers of vinyl acetate are polymerized. It is an amorphous polymer, transparent and soluble in solvents such as benzene, acetone and trichloromethane.
It is polymerized by vinyl acetate in the presence of acetic acid. The degree of polymerization is 250~600. After polymerization, the residual trace catalyst (usually peroxide), monomer and / or solvent are removed by vacuum drying, steam stripping, washing or combined treatment.
In the presence of acetic acid, benzoyl peroxide is used as initiator, vinyl acetate is bulk polymerized, or polyvinyl alcohol is used as dispersant, and the solution polymerized 2 to 6h at 70~90 degree temperature in the solvent. The product is 250~600.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
Colorless latex or colorless transparent bead like solid can be obtained with different polymerization methods. Ethylene acetate is initiated by free radical initiator and can be produced by emulsion, suspension, bulk and solution polymerization. It can also be used as a raw material for polyvinyl alcohol and polyvinyl acetals.
Two butyl phthalate two formic acid, called DBP, is commonly known as two butyl ester. Properties: colorless liquid. The relative density is 1.045. The boiling point is 340 degrees centigrade. Insoluble in water is a plastic, synthetic rubber, artificial leather and other commonly used plasticizers. It is also a solvent and a fixative for spices. It can also be used as a health pest repellent, but the effect is worse than that of two octyl phthalate two formate. The reaction was prepared by the reaction of phthalic anhydride and n-butyl alcohol. Good softness of the product. But the volatility and water extracability are large, so the durability of the products is poor, and it should be gradually restricted to its use.
Two butyl phthalate is a good plasticization of nitrocellulose and strong gel ability. For nitrocellulose coatings, it has a good softening effect. Stability, flexure resistance, adhesion and waterproofing are excellent.
In addition, brought two formic acid butyl ester two is also used as a polyvinyl acetate, alkyd resin, ethyl cellulose and chloroprene rubber plasticizer, also can be used in the manufacture of paints, adhesives, leather, printing ink, safety glass, celluloid, dyes, pesticides, solvents, lubricants and other spices fabric.
Epoxidized soybean oil is light yellow viscous oily liquid at room temperature. Its solubility in water is <0.01 (25 degrees C), the solubility of water in this product is 0.55% (25 C), and it is soluble in hydrocarbons, ketones, esters, higher alcohols and other organic solvents, and it is slightly soluble in ethanol. The product is one of the most widely used PVC nontoxic plasticizers and stabilizers. It has good compatibility with PVC resin, low volatility and small mobility. It has excellent thermal stability and light stability, water resistance and oil resistance. It can give products good mechanical strength, weatherability and electrical properties, and no toxicity. It is internationally recognized chemical process aids for food packaging materials.
Epoxy soybean oil can be used for all polyvinyl chloride products. For example, all kinds of food packaging materials, medical products, all kinds of films, sheets, pipes, fridge seals, artificial leather, floor leather, plastic wallpaper, wire and cable and other daily plastic products, etc., can also be applied to special ink, paint, paint, synthetic rubber and so on. The higher the ESO epoxy value, the better the heat resistance, the lower the iodine value of ESO and the compatibility of PVC, the less easy to precipitate.
