Description
Technical field
The invention belongs to the painting technical field, relate to a kind of compound interpenetrating polymer networks coating and preparation method thereof.
Background technology
Interpenetrating polymer networks (Interpenetrating Polymer Network:IPN) is that two or more crosslinking net polymkeric substance runs through each other, the heterogeneous polymer (also claiming high polymer alloy) that tangles and form
[1-2]Be characterized in: a kind of material randomly intersects infiltration, and machinery twines
[3]In another kind of material, play a part " forcing compatible " and " synergistic effect ", thereby make material neither lose original polymkeric substance inherent characteristic, can obtain the special performance that other polymer blend can't obtain again.This material can improve the dispersiveness of system, interface affinity significantly
[4]Thereby, improve phase stability
[5], realize that polymer performance is complementary, reach the purpose of modification.So IPN shows and polymer blend and the different character of chemical copolymerization thing, promptly in solvent, do not dissolve a swelling and swelling ratio little, IPN can not be wriggled and flow, and good dimensional stability and excellent mechanical strength are arranged
[6]Present paint such as vinylformic acid, alkyd, epoxy, urethane, chlorinated rubber etc. only can satisfy the general industry requirement for anticorrosion.But increasing client is increasingly high to the protective system performance demands, and hopes it in snappiness, sticking power, and aspects such as resistance to acids and bases have the characteristic that is far superior to general coating.Existing coating can not be made high solid coating with the high crosslink density resin, and makes that the viscosity of coating is too high, solid is low, be difficult for construction, VOC content is big, big for environment pollution.
Therefore, the paint film of developing a kind of coating has high-impact, strong adhesive force and resistance to acids and bases becomes present assistant officer technical problem to be solved.
