Abstract
The invention discloses a water-soluble one-component in-die coating for self-skinning polyurethane foam materials and a preparation method of the water-soluble one-component in-die coating. The water-soluble one-component in-die coating is mainly used for the self-skinning polyurethane foam materials and has effects of dying, decorating, protecting and the like on polyurethane material components. The water-soluble one-component in-die coating is mainly applied to industries such as automotive trims, medical apparatus and instruments and furniture and the like at present. Products are strong in covering capability and good in tinting strength and have good adhesive force, wear-resisting performance and suppleness. When the products are used, a solvent type or water-soluble demolding agent is sprayed in a die, then the water-soluble in-die coating is evenly sprayed, a polyurethane material is poured, die assembly is carried out, demolding is carried out after complete curing of foaming, and the in-die coating is evenly attached to the surface of the product.
Description
Technical field
The invention belongs to the technical field of coating, specifically, is lacquer in the self-skin polyurethane foam material use single-component mould.
Background technology
At present, most coating products all is to use after formed product on the market, with the spraying, roller coat, the modes such as showering with applying coating at product surface.And lacquer is the paint that sprays before in-mold molding in the mould, and difference is that general paint is in application after product (workpiece) moulding, and lacquer is to spray before formed product in the mould.
Polyurethane material is one of outstanding synthetic resins of over-all properties.Because its synthon is wide in variety, reaction conditions is gentle, single-minded, controlled, formula adjustment leeway large and the microtexture characteristics of macromolecular material, can be widely used in coating, tamanori, porous plastics, synthon and elastomerics, become people's clothing, food, lived, one of row and the requisite material of high-technology field, itself consisted of the material family of kind, multi-series more than, formed complete polyurethane industrial system, this is that other resin is not available.
At present, automotive upholstery, the members such as medicine equipment, it is to use polyurethane foam material that more parts are arranged, such as vehicle steering, seat etc.
At present, the interior lacquer of mould that is used for the self-skin polyurethane foamed material on the domestic market all is the solvent-borne type product, the import of minority aqueous product is only arranged from external.
At present, on the market polyurethane foam material is adopted the solvent-borne type product more, and often be outer spray mode.This series products generally has following shortcoming:
1. environment protecting is poor, and the organic solvent of solvent-borne type product (VOC) content is greater than 500g/l; The finished product paint film VOC discharging〉500ug/m
3
2. poor stability: the solvent-borne type product is main, belongs to hazardous substance more, and aqueous product is few.
3. part industry (such as automobile industry, medical device industry) to coating products require high, very
Many common coating can not be up to standard.Such as chemicals-resistant, anti-solvent, anti-clean-out system, ageing resistance, wet-heat resisting, weathering resistance requires high.In the solvent borne product, reach above-mentioned requirements, difficulty is little; But at aqueous product, particularly in the single-component water-based product, because of the restriction of system itself, resin and the auxiliary agent space that can select are very little, so often be difficult to satisfy above-mentioned requirements.
4. paint film is to the poor adhesive force of self-skin polyurethane foam material.
5. the snappiness of paint film is poor, can not join with the toughness phase product that the self-skin polyurethane material itself has.In sum, consider from environmental protection and application point, need to develop a environmental protection that meets, safety requirements again can perfect product be joined the water-based in-mould coating from the foam material.
