Abstract
The invention discloses a polyurethane paint. The polyurethane paint is prepared from, by weight, 20-30 parts of polyurethane, 5-15 parts of acrylic resin, 15-30 parts of butyl acetate, 10-20 parts of glycerin, 1-6 parts of polyvinyl alcohol, 0.5-6 parts of limonene, 2-5 parts of triethylenediamine, 1-3 parts of propylene carbonate, 0.5-1 part of a thickener, 0.1-2 parts of an antioxidant and 0.5-3 parts of an antifoaming agent. The polyurethane paint has the advantages of good water, acid-alkali, corrosion and yellowing resistance, and difficult foaming and film efflorescence after meeting moisture.
Description
Technical field
The present invention relates to technical field of chemical paint, especially a kind of high concentrations of toluene diisocyanate.
Background technology
Polyurethane paint paint film is tough, and gloss is plentiful, and adhesive force is strong, water proof and wearable, corrosion resistance, is widely used in high-class woodenware furniture it can also be used to metal surface.The varnish kind of polyurethane paint is referred to as polyurethane lacquer.According to contained component, high concentrations of toluene diisocyanate can be divided into bicomponent polyurethane coating and one-can urethane coating；Difference according to hydroxy-containing component can be divided into acroleic acid polyurethane, alcohol acid and polyurethane, polyester-polyurethane, polyether-polyurethane, epoxy polyurethane；One-pot polyurethane paint, double canned polyurethane paint, three canned polyurethane paints can be divided into according to packaging type；Polyurethane-modified oil paint, moisture solidification polyurethane coating, blocked polyurethane paint, catalytic curing type polyurethane coating and hydroxyl cure type polyurethane coating can be divided into according to composition and membrane formation mechanism.Although polyurethane paint has the weatherability of excellence, but still suffers from wet foaming, the shortcoming of film efflorescence.
Summary of the invention
It is an object of the invention to provide a kind of high concentrations of toluene diisocyanate, this high concentrations of toluene diisocyanate can solve the foaming of high concentrations of toluene diisocyanate tide, the problem of film efflorescence.
In order to solve the problems referred to above, the technical solution used in the present invention is:
This high concentrations of toluene diisocyanate is prepared from by the raw material of following parts by weight: polyurethane 20 parts～30 parts, acrylic resin 5 parts～15 parts, butyl acetate 15 parts～30 parts, glycerol 10 parts～20 parts, polyvinyl alcohol 1 part～6 parts, limonene 0.5 part～6 parts, triethylene diamine 2 parts～5 parts, Allyl carbonate 1 part～3 parts, thickening agent 0.5 part～1 part, antioxidant 0.1 part～2 parts, defoamer 0.5 part～3 parts.
In technique scheme, more specifically technical scheme is it may also is that thickening agent is one or more in methylcellulose, hydroxypropyl methyl cellulose and hydroxyethyl cellulose.
Further, antioxidant is dibenzylatiooluene or propylgallate.
Further, defoamer is OPEO.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, high concentrations of toluene diisocyanate of the present invention is prepared from by polyurethane, acrylic resin, butyl acetate, glycerol, polyvinyl alcohol, limonene, triethylene diamine, Allyl carbonate, thickening agent, antioxidant and defoamer are compound, overcomes that conventional urethane paint wet is easy to foaming, the problem of film efflorescence.
2, high concentrations of toluene diisocyanate of the present invention is water-fast, acid and alkali-resistance, corrosion-resistant, anti-yellowing property is preferable.
