Currently, when being constructed using the common clear bottom material of polyurethane, in order to reinforce the sealing effect of bottom, to increase
Add coating thickness, it may appear that the problems such as heat rash appears, poor adhesive force, poor grinability.
Summary of the invention
In view of the deficiencies of the prior art, an object of the present invention is to provide a kind of anti-transparent polyurethane that heat rash appears of thick painting
Material, has a good paint film property, thickness apply it is anti-heat rash appears has excellent performance, levelability, richness, adhesive force, grinability etc. are comprehensive
Conjunction is had excellent performance, and is increased operation rate, while achieving the purpose that environmental protection；Another object of the present invention is anti-to provide a kind of thick painting
The preparation method for the transparent polyurethane material that heat rash appears.
Technical purpose of the invention is achieved through the following technical solutions:
The present invention provides a kind of anti-transparent polyurethane material that heat rash appears of thick painting, according to parts by weight, the transparent poly- ammonia
Ester material is grouped as by following group:
As a further optimization solution of the present invention, the alkyd resin is anti-for Zhan Chen new material Group Plc
Heat rash appears alkyd resin.
As a further optimization solution of the present invention, Malin's acid resin is the BC-530 of Po Lam resin.
As a further optimization solution of the present invention, the rosin resin is the TX90 of the prosperous pine resin Co., Ltd in Zhejiang.
As a further optimization solution of the present invention, the multifunctional alcohol acid resin modifying agent is that micro- coating additive is gathered in Shanghai
The FDA-501 of company.
As a further optimization solution of the present invention, the solvent is dimethylbenzene, butyl acetate and propylene glycol monomethyl ether acetic acid
The mixture of ester.
As a further optimization solution of the present invention, the dimethylbenzene, butyl acetate and propylene glycol methyl ether acetate press matter
Amount is mixed than 4-8:2-5:1-2.
As a further optimization solution of the present invention, it is China's auxiliary agent company HX2300 without organic that the defoaming agent, which is selected,
The brokenly bubble polymer solution of silicon, the dispersing agent are the polymer electrolyte dispersion of 50% active quantities of Bei Teer Chemical Co., Ltd.
Agent BD-8142, the levelling agent is the mixture of the BYKETOL-OK high boiling aromatic hydrocarbons of Bi Ke chemistry, ketone and ester, described inorganic
Filler is 1250 mesh talcum powder of wide victory, and the grinding auxiliary agent is zinc stearate TV-A.
The present invention also provides a kind of thick preparation methods for applying the anti-transparent polyurethane material that heat rash appears, include the following steps:
(1) parts by weight are pressed, it is modified to prepare alkyd resin, Malin's acid resin, rosin resin, multifunctional alcohol acid resin
Agent, solvent, defoaming agent, dispersing agent, levelling agent, inorganic filler and grinding auxiliary agent；
(2) alkyd resin and solvent are mixed, dispersion stirs 5-10 minutes extremely under the speed conditions of 800-1000r/min
Uniformly；
(3) sequentially added under the speed conditions of 400-600r/min into step (2) gains dispersing agent, defoaming agent and
Then revolving speed is turned up to 800-1000r/min, dispersion stirring 10-15 minutes in levelling agent；
(4) Malin's acid resin, rosin are sequentially added into step (3) gains under the speed conditions of 400-600r/min
Then revolving speed is turned up to 1200-1400r/min in resin, talcum powder and grinding auxiliary agent, dispersion stirs 25-30 minutes to mixture
Fineness≤50um；
(5) it is modified that multifunctional alcohol acid resin is added into step (4) gains under the speed conditions of 400-600r/min
Agent and propylene glycol methyl ether acetate, are then turned up revolving speed to 800-1000r/min, and dispersion stirring 10-15 minutes is to uniform, i.e.,
?.
Invention mechanism of the invention is:
In the drying process due to film, the volatilization of solvent, cross-linking reaction carry out cause the bubble inside film to fail
Release completely.Film is not yet fully cured, but smears still in liquid-liquid state or gelatinized, thus bubble still have it is certain
Locomitivity ultimately causes film coated surface and is jacked up, and is formed " prickly heat ".The present invention uses the limited public affairs of Zhan Chen new material group share
Department is anti-heat rash appears alkyd resin；Rosin resin, rosin acid contain double-strand and carboxyl-reactive gene, have conjugated double bond and allusion quotation
The reaction of type carboxyl.Other than itself being easy to oxidation and isomerization reaction, the double bond also with disproportionation, hydrogenation, addition, polymerization is reacted.
It also there is esterification, alcoholization simultaneously, is reacted at carboxyls such as salt, decarboxylation, ammonolysis, the volatilization of solvent, cross-linking reaction can be effectively eliminated
Carry out causing the bubble inside film, addition reaction carried out with rosin and maleic anhydride in compounding and with glycerol esterification and
Malin's acid resin better effect obtained.Such method, which has, excellent thick applies anti-heat rash appears ability.
The beneficial effects of the present invention are:
(1) material of the present invention has a good paint film property, and thickness applies that anti-heat rash appears has excellent performance；
(2) excellent combination properties such as levelability, richness, adhesive force, grinability.
