Description

A kind of Acrylic transparent powder paint

Technical field

The invention mainly relates to a kind of coating, particularly relate to a kind of Acrylic transparent powder paint。

Background technology

Heat curable powder coating refers to using thermosetting resin as film forming matter, added the firming agent of cross-linking reaction heated after can form insoluble not molten quality hard coat。Temperature this coating high again softens without as thermoplastic coating, and can only decompose。The resin adopted due to thermosetting powder coating is the prepolymer that the degree of polymerization is relatively low, molecular weight is relatively low, so the levelability of coating is better, there is good dicoration, and low-molecular-weight prepolymer cured after, the macromole of cross-linked network can be formed, thus coating has better anti-corrosive properties and mechanical performance。Therefore thermosetting powder coating development is particularly rapid, and in order to improve the overall performance of conventional powder, by adding new compounded mix etc., to improve its performance be necessary。

Summary of the invention

The object of the invention is contemplated to provide a kind of Acrylic transparent powder paint。

The present invention is achieved by the following technical solutions:

A kind of Acrylic transparent powder paint, it is characterised in that it is made up of the raw material of following weight parts:

Described compounded mix is made up of the raw material of following weight parts:

Laterite 50-60, bone meal 4-6, iron mine ground-slag 10-13, wollastonite in powder 5-7, sodium tripolyphosphate 1-2, Dodecyl trimethyl ammonium chloride 2-3, Eucalyptus oil 1-2；

By above-mentioned laterite, iron mine ground-slag, wollastonite in powder mixing, calcine 3-4 hour at 600-800 DEG C, cooling discharging, add Eucalyptus oil, mix homogeneously, obtains premix material, is joined by sodium tripolyphosphate in 15-20 times of water, it is stirring evenly and then adding into Dodecyl trimethyl ammonium chloride, raise temperature and be 60-80 DEG C, with above-mentioned premix material mixed grinding, drying, cross 80-100 mesh sieve, obtain described compounded mix。

The preparation method of a kind of Acrylic transparent powder paint, comprises the following steps:

Above-mentioned N-phenyl-3-TSL 8330 is mixed with Fluorspar Powder, hydration zinc borate, it is heated to 55-60 DEG C, 400-600 rev/min dispersed with stirring 2-3 minute, mix with remaining each raw material, put into mixing in high-speed mixer abundant, then gained compound is put into mixing extrusion in high-speed extruder, after then tabletting crushes, pulverize then through atomizer, sieve, obtain described Acrylic transparent powder paint。

The invention have the advantage that

Acrylic transparent powder paint of the present invention has heigh clarity and excellent levelability, anti-thread splendid with crazing, and can solidify under cryogenic, is particularly suitable for aluminum wheels of automobiles and car surface spraying。
