Abstract
The invention relates to a special self-stratifying antifouling type powdery coating for a polypropylene-made bathroom product. The powdery coating is prepared from a component A and a component B, wherein the weight ratio of the component A to the component B is (0.5 to 4): 1; the component A is prepared from the following raw material components in parts by weight: 520 to 860 parts of epoxy resin, 60 to 280 parts of a phenols curing agent, 105 to 350 parts of pigment fillers, 10 to 30 parts of an adhesion promoter and 12 to 28 parts of an auxiliary agent; the component B is prepared from the following raw material components in parts by weight: 500 to 900 parts of special acrylic resin, 50 to 180 parts of a carboxyl curing agent, 10 to 200 parts of fillers, 70 to 170 parts of a pigment and 20 to 50 parts of an auxiliary agent. The powdery coating is automatically stratified when being cured; a bottom layer provides excellent adhesion and protection performances for a base material and a top layer provides excellent antifouling and decoration properties for the base material.
Description
Technical field
The invention belongs to powder coating technology field, relate to decorative powder coatings, especially a kind of polypropylene material is defended
Bathe the special self demixing anti-fouling type powdery paints of product and preparation method and application.
Background technology
Polypropylene, is a kind of thermoplastic resin prepared by propylene polymerization, nontoxic, tasteless, density is little, it is good to have
Mechanical property, moulding processability are good, have higher thermostability, and use temperature is up to 110-120 DEG C continuously, and polypropylene
Chemical property is good, absorbs water hardly, does not reacts with most chemical drugss, and quality is pure, avirulence.Polypropylene product
Production technology has that automaticity is high, scrappage is low, pollution-free, low-carbon (LC), exempt from the significant advantages such as high-temperature firing.Use polypropylene
Sanitaryware prepared by material, can be prevented effectively from the highly energy-consuming of traditional ceramics sanitaryware production technology, high pollution, maximum discharge etc.
Shortcoming, thus receive much concern in recent years.But polypropylene articles also has shortcoming, such as in use easy light, heat and the effect of oxygen
Aging, and coloring is bad.Additionally, due to sanitaryware Long Term Contact hot and cold water, Acidity of Aikalinity cleaning product etc., and polypropylene material
The material hydrophilic materials such as substantial amounts of calcium carbonate that add more, therefore its heatproof, water-fast, resistance to acids and bases is limited.Therefore, polypropylene material
Sanitaryware need to carry out coating protection and beautify.
