Preparation Method.
Technical background
Nearly more than ten years China's plastics industry rapidly develops, and the wide engineering plastics of domestic application have ABS, PG, PA, POM,
General-purpose plastics has PS, PC, PP, PVC etc..Plastic products are light, high specific surface area, easily batch production, it has also become national economy
With the indispensable material of people's lives.
Plastics are amorphous polymers, it has good comprehensive performance, and can carry out secondary operation to plastic products,
Therefore it is widely used on household electrical appliances, food, toy, medical or similar products.But since the plastics such as PP or PE are nonpolarity
Material has extremely low surface energy, it is difficult to be painted again on surface layer, coating processing, influences subsequent clients to appearance and surface
The requirement of performance.
Coating can adhere on PP plastics, be since there are two types of the presence of effect.One kind is that physical mechanical acts on, PP plastics
Product surface has uniform micro-rough structure, after coating sprays to this micro-roughened surface, in liquid condition with regard to energy
In " hole " that invades micro-rough, it is dry after coating crosslink, paint film just as nail " nail " on PP plastic products, this
It is exactly that mechanical anchor closes lock effect.Another kind is exactly chemical bond, contains certain polar group in PP molecules, due to being applied
The erosion of solvent in material, these polar groups are activated, and chemical bond are formed with some polar groups in coating, with coating
Curing, the two crosslink.Meanwhile the erosion of the solvent in coating also makes PP frostings generate pit, so as to also be machinery
Anchor closes lock effect and creates condition.

CPP can be fully swollen by solvent, reheats mixture being dissolved into solution.
The reference formulation of finishing coat：Everbright fast yellow 12g, DFA1580 25g, BS1201 40g, DF133 10g, wetting dispersing agent
In right amount, appropriate levelling agent, appropriate antifoaming agent, diluent 10g.The fineness of all coating is all 2O~25 μm.
3rd, coating performance is tested
The test of coating performance carries out after forming a film 7 days.
Adhesion performance of coating：It is tested by GB/T9286-1998；
Coating pencil hardness performance：It is tested by GB/T6739-2006；
The resistance to alcohol performance of coating：Model is placed in absolute ethyl alcohol, is impregnated 1 hour at ambient temperature, is taken out, dries,
The variation of coating is observed, judges the resistance to alcohol performance of coating；
Coating water boiling resistance：Model is placed in 80 DEG C of deionized waters, is impregnated 1 hour, is taken out, dries, observing samples apply
The variation of layer；
Coating abrasion performance is tested：By the standards of QB2506-2001, uniformly wiped back and forth under 500g counterweights with 0000# steel wool
It wipes, the number wiped during cut occurs in calculating.
The wearability of coating：Sample is placed under the 0000# steel wool for being placed with 500g loads, sample surfaces are carried out back and forth
Friction 40 times, it is excellent to remember 0~5 cut, and 5~10 cuts are good, and 10 or more cuts are poor, judge to apply according to cut quantity
The wearability of layer.
Performance comparison is as follows：
Conclusion：1. the adhesive force for the coating being coated on common PP can only achieve 2~3 grades, expected mark is not achieved
Standard in the adhesive force of coating being coated on PP made of the accelerating agent for being added to the present invention at 0~1 grade, reaches industry production
The requirement of product, the levelability of coating is fine, is not in shrinkage cavity and serious lifting phenomenon, surface drying time is in 4min or so.2. it tries
If the resin single choice thermoplastic acrylic resin tested, the adhesive force of coating is poor, ethyl alcohol impregnate after coating peeling, come off
Seriously, this shows that the adhesion between the coating and thermoplastic acrylic resin that prepare is poor so that coating is resistance to alcohol repellency poor；But
After being addition adhesion promoter, though appearance of coat after curing, without significant change, performance change is notable.
