Tri-beta-methylglycidyl - glycidyl coating crosslinking agent of isocyanurate
Compared with those of TGIC due to its beta contain methyl, influenced by space steric hindrance its reactivity fall greatly, therefore need to join in the preparation process of powder coating catalyst, which affect the storage stability.
But it is the closest agent to TGIC, which the manufacturer claims is far less toxic than TGIC and does not need to post toxic labels.
The influence of polymerization process on the surface tension and foaming properties of the emulsion. The surface tension of non-soap emulsion, microsoap emulsion and regular emulsion decreases in turn. Accordingly, their bubbles increased in turn. Therefore, the application of non-soap emulsion polymerization and microsoap emulsion polymerization is helpful to solve the problem that the emulsion type product can produce foam during production and construction.
It is best to use regular emulsion polymerization film. Soap-free emulsion and micro soap-free emulsion particle size while the conventional emulsion, but lower the luster of the film, this is mainly because less dosage of emulsifier, with paint paint is easy to produce flocculation, in the process of coating surface appear small bumps, coating caused by uneven, luster. The effect of polymerization process on the impact resistance, hardness and adhesion of the coating film at room temperature was not significant.
The conventional emulsion polymerization process, the room temperature crosslinking acrylic emulsion paint solid content is higher, gloss and fullness of the coating is better, and use soap and soap emulsion polymerization process, the coating has good resistance to water, coating of foaming ability is low. The appropriate amount of DAAM is 6.5 percent of the total monomer mass.
The gloss, hardness and dry performance of the paint film with rosin as base material are better than oil paint, but the paint film is soft and sticky, and the light protection is poor in the exposed atmosphere. The film is permanently whitened by water and is quickly destroyed by climate change, friction or alkali. So rosin is rarely used for painting alone.
There are artificial petroleum pitch, coal pitch and natural asphalt, etc. Asphalt has unique corrosion resistance, cheap and easy to construct.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Also known as purple gum, dry lacquer, soluble in alcohols, ketones and alkali solutions. The characteristic of shellac varnish is to use convenient, dry quick, the lacquer film is hard and bright, the bent is good, have good electrical insulation performance. Apply to the wood surface of the bottom and the advanced furniture out of the light. The disadvantage is water resistance and weather resistance, sun exposure will lose light, hot water will pan white.
Natural lacquer and its modified coatings
(1) natural lacquer: it is filtered by the liquid juice of the lacquer tree, which is a kind of milky white or grayish yellow sticky liquid with air contact, the color gradually becomes darker.
(2) the chemical components of natural lacquer: natural lacquer mainly consists of urushiol, lacquer enzyme, and glia.
(3) the properties of natural lacquer: the paint film is solid, glossy, excellent acid resistance, water resistance, oil resistance, corrosion resistance, abrasion resistance, paint film not stickiness, high power, etc. The disadvantage is that it is dry and slow, and the paint film can be fast and dry in humid environment. It is not resistant to strong alkali and strong oxidant. It is very toxic and can cause allergic dermatitis.
The diluents of the paint are mainly gasoline, and other diluents are turpentine, alcohol, benzene, etc. Storage time should not be too long. Normally stored in a cool, dry, insulated, light - sealed container.
There are several kinds of natural modification paints that are suitable for natural lacquer modification:
Lacquer: the film is tenacious, with a certain bent force, good mechanical properties and chemical corrosion resistance, suitable for large and fast construction requirements. Widely used in chemical fertilizer, chemical equipment, machinery and agricultural equipment, it requires water, acid and other metals, wood surface coating, but not suitable for direct sunlight.
Lacquer: non-toxic, light color, suitable for lacquer decoration, used in wood furniture, yarn tube, lacquer chopsticks and various kinds of car and boat decoration.
The oil - based paint: heat - resistant, light - resistant, anti - water resistance, durable, weather resistant, high - bent, hard, bright, transparent, color, etc. Used for wood furniture, doors and Windows, indoor furnishings, etc.
Phenol epoxy anticorrosive paint: excellent acid resistance, alkali resistance and good physical mechanical properties. It can also be dried and dried, widely used in agricultural plant protection machinery, and can also be used in Chinese workers and other places.
