preparation example Construction

[0078] Two, the preparation method of the described styrene-free unsaturated polyester putty comprises the following steps:

[0079] (1) Preparation of self-made styrene-free unsaturated polyester resin in the described A component:

[0080] ① First, according to the mass ratio of the raw materials of the self-made unsaturated polyester resin without styrene, the formulation amounts of the four raw materials of propylene glycol, diethylene glycol, maleic anhydride and phthalic anhydride and The two raw materials of antioxidant BHT with half the formula and hydroquinone with half the formula are put into the reactor together;

[0081] ② Gradually raise the temperature to 140°C until the solid melts, then raise the temperature to 180-185°C, drain part of the water, and carry out the heat preservation reaction. When the acid value is less than 90mgKOH / g, add the remaining amount of antioxidant BHT and After quinone and PB-713 according to the mass ratio are put into the reactor ...

example 1

[0093] A component formula: 32 parts of self-made unsaturated polyester resin without styrene, 3 parts of titanium dioxide, 6 parts of thixotropic agent, 0.8 parts of dispersant, 0.2 parts of composite stabilizer, 2 parts of composite drier, viscosity adjustment 6 parts of agent, 8 parts of surface sealant, 36 parts of talcum powder, and 6 parts of functional filler.

[0094] B component formula: 3 parts of antioxidant colorant, 20 parts of methyl ethyl ketone peroxide, 20 parts of cyclohexanone peroxide, 0.4 part of fumed silica, and 0.2 part of vinylpyrrolidone.

[0095] (1) Put the self-made styrene-free unsaturated polyester resin and titanium dioxide into the high-speed disperser, mix evenly under the condition of 1000-1200r / min, and obtain a coarse suspension without obvious particles;

[0096] (2) Transport the above-mentioned coarse suspension to a sand mill and grind to a fineness of ≤20 microns to obtain a titanium white slurry;

[0097] (3) Transport the titanium d...

example 2

[0101] The difference between Example 2 and Example 1 lies in the proportioning of component A; while the proportioning of component B and the preparation method and process of components A and B are the same as those in Example 1.

[0102]A component formula: 38 parts of self-made unsaturated polyester resin without styrene, 4 parts of titanium dioxide, 4 parts of thixotropic agent, 1.6 parts of dispersant, 0.4 parts of composite stabilizer, 3 parts of composite drier, viscosity adjustment 2 parts of agent, 4 parts of surface sealant, 40 parts of talcum powder, and 3 parts of functional filler.

Abstract

The invention relates to an unsaturated polyester putty containing no styrene for high-speed trains and locomotives and a preparation method. The unsaturated polyester putty containing no styrene is prepared from a component A and a component B, wherein the component A is prepared from self-prepared unsaturated polyester resin containing no styrene, titanium dioxide powder, a thixotropic agent, adispersant, a compound stabilizer, a compound drier, a viscosity modifier, a surface sealing agent, talcum powder and functional filler; the component B is prepared from an antioxidizing coloring agent, methyl ethyl ketone peroxide, cyclohexanone peroxide, vapor-phase silicon dioxide and vinyl amide type functional polymer. The unsaturated polyester putty containing no styrene has the advantages that any irritating odor is avoided, the adhesion force is excellent, the dryness is good, the service life is long, the flexibility is good, the shock-resistant property is good, and the unsaturated polyester putty is suitable for large-area construction of the high-speed trains and the locomotives; the environment-friendly effect is good; the unsaturated polyester putty is a high-property environment-friendly priming material for replacing the traditional putties for the high-speed trains and the locomotives.

Description

technical field [0001] The invention relates to a styrene-free unsaturated polyester putty for high-speed railways and locomotives, which belongs to the field of coatings, in particular to a high-performance primer material suitable for high-speed railway locomotives, which is a styrene-free putty Saturated polyester putty and its preparation method. Background technique [0002] Since the 1980s, my country has introduced unsaturated polyester putty (called putty on the market) from Japan, Germany, the United States and other foreign countries. In the past 30 years, all provinces in China have developed their own "atom ashes" with similar performance and different varieties and brands. At present, they are widely used in the manufacturing industries of rolling stock, automobiles, and electrical machinery. [0003] Looking at the market, no matter the products such as unsaturated polyester putty (putty) produced at home and abroad, all must be the base material through unsat...
