Crosslinking agent for water-based wood paint paint

Crosslinking agent for water-based wood paint paint

Since the 1960 s, the world is becoming more and more attention of volatile organic compounds (VOC) of atmospheric pollution, industrial developed countries also established a dedicated management institution, formulate various laws and regulations on the amount of solvent evaporation coating when strict restrictions. Therefore, various environment-friendly coatings have emerged.

As an important part of the coating industry, wood lacquer, also has experienced a significant change, the water-based wood lacquer is developed rapidly.

The Chinese water-based wooden ware is late, the overall technical level is relatively backward, and the quality of the products is mixed. Currently, water-based wood lacquer is mainly acrylic, mainly used in water-based wooden door, door frame, wall panel, children's toy board and so on.

Although the proportion of waterborne wood paint usage in our country is not big, but as people for deepening understanding of healthy environmental protection, and the influence of all aspects of the living environment, whether in wood coating of choose and buy directly in the future, or the corresponding wood products, with water as the primary reference.

Believe in in the future market whether be water wood ware coating, still be the wood furniture that is decorated by water of water of water of water of paint, toy and so on will become the product of hot demand. At present, the water-borne wood lacquer is still the hardness, the water resistance is not enough, the problem of the problem such as poor fullness and high temperature return.

As a result of water-based paint to introduce a large number of hydrophilic group and the difference with solvent-based coating film-forming mechanism, makes compared with the same or similar molecular structure, solvent coating, waterborne coating is hard to exceed its performance. At present, the pencil hardness of the water-based paint product in the market can reach 2H is very few, this is the key of the study of water-borne wood lacquer.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


This article USES the diacetone acrylamide/adipic acid hydra

zide crosslinking system, using the crosslinking technology to solve the waterborne wood coatings exist problems such as hardness, water resistance, has important theoretical and practical significance.

Laboratory materials and instruments. Materials and medicines: (I T A) itaconic acid, methyl acrylic acid, butyl acrylate (M A A) (A, B), methyl methacrylate (MMA), styrene (ST), diacetone acrylamide (DAAM), adipic acid hydrazide (ADH), sodium dodecyl sulfate (K12), sodium dodecyl diphenyl ether disulfonic acid (a1), alkyl alcohol polyoxyethylene (3) ammonium sulfate salt (DNS - 28 A), branched chain heterogeneous carbon 13 fatty alcohol polyoxyethylene ether (TO - 7), sodium bicarbonate, ammonium persulfate, amino - 2 - methyl - 2-1 - propanol (AMP - 95), 12 (Eastman) ester alcohol, Twin 4100 wetting agent, organic silicon flow ping agent, AF QS - 102-013 - A organic silicon defoamer, MD - 2000 water-based wax, silicon dioxide, polyurethane thickener: DL - 2020 - B.

Experimental apparatus: D120-2 f mixer, HQ - S11 water bath pot, precision peristaltic pump BT600-2 j, JJ500Y electronic scales, GZX - 9030 digital display drying oven, VFS - 230 high-speed dispersion machine, minimum film-forming apparatus KQDM - 03, SLD - 500 - d electronic universal testing machine.

The preparation of water-based wood ware and its woodwork products

(1) the preparation of waterborne wood varnish: according to the experimental formula of quantitative said emulsion. A, 600 RPM/min under the conditions of stir with pre-mixed water, ester, alcohol after 12, Twin 4100 wetting agent, organic silicon flow ping agent, QS - 102-2 0 0 0 M D water-based wax, silicon dioxide, 1500 RPM / 15 min min dispersion, the dispatch speed to 600 RPM/min, join AF - 013 - A organic silicon defoamer, use of DL - 2020 - b adjust viscosity and slow defoaming for 10 minutes, as shown in table 1.

(2) wood lacquer sample print: in advance has been back and primer coating on the board made of water-based varnish, 24 hour in 45 ℃ oven, and set aside.
