Description
Technical field
The present invention relates to unsaturated polyester resin coating, specifically refer to, for preventing a kind of waterproof flame-retardant quick-drying semitransparent unsaturated polyester insulating paint that batteries of electric automobile group generation race leaky provides and preparation method thereof.
Background technology
Unsaturated polyester resin (unsaturated polyester resin, UPR) formed by high molecular linear polyesters (UP) and low molecule unsaturated monomer two portions copolymerzation with cross-linking, its linear polyesters normally dibasic alcohol, unsaturated dibasic acid (acid anhydride) and monounsaturated dicarboxylic acid (acid anhydride) makes through polycondensation.Except that containing ester group, also has unsaturated double-bond (CH=CH-) in the unsaturated polyester resin molecular backbone chain.Therefore, it has the characteristic of typical ester bond and unsaturated double-bond, it is dissolved in the linking agent monomers such as vinylbenzene, becomes the liquid resin of transparent homogeneous.Unsaturated polyester is long-chain shape molecule before curing, and its relative molecular weight is generally 1000～3000, and this long-chain shape molecule can formation has the huge network molecule of complex construction with unsaturated monomer is crosslinked.Unsaturated polyester resin has 100% response capacity, and promptly liquid resin can all change solid polymer into and not isolate by product under the effect of initiator etc., can be at the proper temperature compacted under, and applied range, processing performance is good.
Power supply such as industrial and mining enterprises and automobile position is because human electric shock's accident that various factors causes, mouse, animalcules such as snake enter substation etc. and cause short circuit between bus, outdoor the sending between electric bare wire that thunderstorm gale causes contacts short circuit, accidents such as the contact of electromobile electric wire is on fire often take place, line short is on fire etc., light then cause supply line's large-area power-cuts and burn out resident's household electrical appliance, cause hundreds of thousands of for country and individual, and even financial loss up to a million, heavy then cause casualties, moreover, because electrical equipment, cable catches fire and spreads, and it is huge to the loss that national economy causes to lead to the fire disaster accident.Fire-retardant unsaturated polyester coating with the insulation dual function of the present invention solves the problems referred to above.Operating modes such as electromobile, colliery and chemical enterprise in addition, environment is more abominable, needs more to give that coating is heat-resisting, other performance such as waterproof and acid and alkali-resistance.
More existing at present patent reports about the unsaturated polyester resin flame-retardant insulation compound.Chinese invention patent CN1803918 adds decabromodiphenyl oxide, antimonous oxide and Shawinigan black in the unsaturated polyester resin to as fire retardant, makes it have flame retardant properties, but the environmental requirement that can't reach now to be advocated.Unsaturated polyester resin among the Chinese invention patent CN101186779A has adopted halogen-free flame retardants to improve its flame retardant properties, but this coating needs could solidify under the heating condition, and the construction technology condition is had certain restriction.
Summary of the invention
The object of the present invention is to provide a kind of have high insulation and excellent flame retardancy energy, have waterproof flame-retardant quick-drying semitransparent unsaturated polyester insulating paint of erosion resistance and preparation method thereof simultaneously.
