Abstract

The invention provides a preparation method of an insulation wear-resistant polyurethane paint. The paint comprises a component A composed of unsaturated polyester (70-90%) and 2,4-dichlorobenzoyl peroxide (10-30%) and a component B composed of styrene (80-90%), tobulene-2,4-di[N,N-dimethylaminopropylurea] (5-10%) and asphalt (5-10%). The prepared paint has the advantages of good curing performance, rapid drying, strong adhesive force, high dielectric coefficient, dampness resistance, heat resistance, and wide application prospect.

Description

The preparation technology of a kind of insulation, resistant polyester paint

Technical field

The present invention relates to a kind of paint, the preparation method of particularly a kind of insulation, resistant polyester paint, belongs to chemical field.

Background technology

Painting large is in early days main raw material mainly with vegetables oil, therefore is called " paint ".Paint plays very important effect to the progress of human lives.Enter 21 century, on the one hand, the development of social productive forces and growth in the living standard, new requirement is constantly proposed to the kind of painting and quality, on the other hand, the progress of science and technology, particularly vitochemical development, the continuous appearance of novel resin, for the large production of coating provides possibility, many new oil paint materials are come out one after another.Occur that clinging power is larger, the paint of higher, fire-retardant, the anticorrosive shades of colour high with thermostability of glossiness.

Current paint has more than several thousand kinds.By whitewashing position classification, be mainly divided into wall paint, metallic paint, wood lacquer.Wall paint comprises exterior wall paint, interior wall paint and end face paint, mainly emulsion paint; Metallic paint is enamel paint mainly; Wood lacquer mainly contains pyroxylin(e)finish, Polyester Paint etc.

Polyester Paint is the one of conventional paint, and it is a kind of polycomponent paint, is be the thick matter paint of one that main film forming matter is made with vibrin.The nineties in 20th century, after Polyester Paint imports China into, just instead of varnish very soon, become a kind of main paint.Polyester Paint is by adding a certain amount of pitch, insulation, wear-resisting paint can be prepared, be widely used in motor, electrical equipment coil and insulation component, and fill its gap and micropore, to dry or after heating, drying, a closely knit entirety is formed in solidification, thus improves its disruptive strength, mechanical property.Paint curing performance prepared by present method is good, quick-drying, adhesive power strong, have thermo-elasticity; Corrosive nature is not played to copper and coil or other materials; There is higher dielectric, moisture resistance, thermotolerance, be with a wide range of applications.

Summary of the invention

The object of this invention is to provide the preparation method of a kind of insulation, resistant polyester paint.

This paint comprises A and B two component, and component A is unsaturated polyester and 2.4-dichlorobenzoperoxide, and B component is vinylbenzene, Toluene-2,4-diisocyanate, 4-bis-[N, N-dimethylamino third urea] and pitch, and each component formula content is as follows:

Component A

Unsaturated polyester: 70%-90%

2.4-dichlorobenzoperoxide: 10%-30%;

B component

Vinylbenzene: 80%-90%

Toluene-2,4-diisocyanate, 4-bis-[N, N-dimethylamino third urea]: 5 %-10%

Pitch: 5%-10%;

The preparation method of a kind of oil resistant, corrosion-resistant paint carries out as follows:

(1) first the component A material containing main paint is heated to 40-50 DEG C;

(2) slowly added in B component by component A material after heating, do not stop to stir, make it mix, the ratio control added is between A:B=2:1 and 3:1 again;

(3) when modulation has certain viscosity, just can be brushed to body surface or be filled in electric elements gap, the unsaturated double-bond in the main chain of polyester under the effect of 2.4-dichlorobenzoperoxide solidifying agent with carry out radical copolyreaction and film-forming as strong solvent vinylbenzene.

The present invention has following advantages and characteristic:

(1) good, the quick-drying of the paint curing performance prepared of present method;

(2) paint has higher dielectricity, does not play corrosive nature to copper and coil or other materials;

(3) the preparation technology of this paint is less demanding, and flow process is simple, is with a wide range of applications.
