Description
Technical field
The present invention relates to building external paint, refer in particular to a kind of composite building external paint.
Background technology
After the BC-01 phenylpropyl alcohol building external paint construction at present, easily show-through after the existence brushing usually, early stage water tolerance is bad, waits shortcoming time of drying slowly.Shortcoming at the existence of BC-01 phenylpropyl alcohol building external paint, the Chinese insulation of existing document net is found, the construction of building external paint (one) is mentioned solvent type exterior wall coating, general humidity is greater than constructing under 85% the situation, because of dried coating film very slow, influence sticking power, metope is grown dim, to water-based exterior wall paint and how to improve prescription and do not mention.At the Chinese patent net, keyword, the modification of phenylpropyl alcohol building external paint, search development with organosilicon grafted and modified benzene emulsion and high performance outer wall paint, can improve waterproof, the weathering resistance of phenylpropyl alcohol coating, but not be resolved to early stage water tolerance is bad, price is still higher.
It is main film forming matter that the present invention adopts compound emulsion, is film forming subsidiary material with the composite film former, and the composite building external paint that is mixed with does not appear in the newspapers in all searching documents.
Summary of the invention
The purpose of this invention is to provide a kind of composite building external paint, it is composited by compound emulsion, composite film former, filler and solvent etc.Shortcomings such as solution is easily show-through after brushing, and early stage water tolerance is bad, the comprehensive technical performance of raising coating.
Wherein the add-on of compound emulsion is 30%～45%, the add-on of composite film former in coating is 1-10%, solvent (water) 10%～20%, titanium dioxide 5%～10%, talcum powder 5%～10%, calcite in powder 5%～10%, wollastonite powder 5%～10%, other auxiliary agents 1%～2% such as defoamer, thickening material, sanitas.
Solvent and composite emulsion, composite film former, dispersion agent, filler are added in the reactor, and high-speed stirring 1h adds auxiliary agents such as sanitas, defoamer again, and high-speed stirring 0.5h uses colloidal mill (or sand mill) to grind two times, packing then.
1. the development of composite emulsion.
Compound emulsion mainly is composited by benzene emulsion BC-01, acetate emulsion VAC and three kinds of emulsions of polyvinyl alcohol emulsion PVA.Wherein benzene emulsion BC-01 is 83%～89%, and VAC is 4%～7%, and PVA is 7%～10%.2, the development of composite film former
Mainly selecting A for use is that ethylene glycol, B are that butyl glycol ether, C are that propylene glycol, D are that propylene glycol butyl ether, E are 2,2,4-trimethylammonium-1,3-pentanediol list isopropylformic acid fat is combined to form composite film former, wherein the component of each membrane-forming agent is A5%-20%, B5%-20%, C15%-30%, D20%-30%, E20%-40%.
Major advantage of the present invention: have preferably cohesive force, opacifying power, alkaline-resisting, water-fast, brushing resistance, an advantage such as time of drying is fast, cost is low, early stage waterproof ability is strong, overcome the deficiency of BC-01 coating, product performance are more superior than BC-01 coating, cost is lower than like product, occupies leading domestic level.Have certain social benefit, economic benefit and scientific value.Pollution-free in process of production, be a product that less investment, instant effect are worthy to be popularized.Its compound emulsion recombination mechanism is: because the BC-01 emulsion is a kind of high molecular polymer, can be dispersed in and forms emulsus in the water.Unstable easily coagulation when development coating; in the BC-01 emulsion, add VAC emulsion and PVA resin solution after micronize, emulsification; can form a kind of protection adsorption layer on the polymer particles surface; prevent emulsion particle mutually near and coagulation; can improve compound emulsion cohesive force, alkaline-resisting, water-fast, brushing resistance; add composite film former and can improve early stage waterproof ability, accelerate time of drying.Change packing variety and can prevent easily grinning effect of brushing back, this compounding technology has improved the over-all properties of coating greatly.This coating is mainly used in external wall, and less investment, cost are low, excellent property, good development prospect is arranged.
