Abstract
The invention discloses a kind of casting alcohol-based coating, formula includes following component：10 ~ 25 parts of refractory aggregate, 50 ~ 60 parts of carrier, 2 ~ 7 parts of binder, 10 ~ 15 parts of suspending agent, 8 ~ 49 parts of additives.A kind of casting alcohol-based coating of the present invention has excellent viscosity, brushability, sag resistance, levelability, permeability, suspension, being coated with property and thixotropy.
Description
Technical field
The present invention relates to a kind of technical fields of coating, and in particular to a kind of casting alcohol-based coating.
Background technique
Alcohol-base paint due to its with rate of drying fast, high production efficiency, low in cost, the with short production cycle, scope of application
The advantages that wide, has been used widely in China.Annual consumption is up to 3 ~ 40,000 tons, and usage amount shows a increasing trend, market prospects
It is wide.But there are many problems in the alcohol-base paint that China voluntarily produces, as suspension is poor, advection poor, easy in use
Volatilization, refractory aggregate sink to being formed " silent as the grave shallow lake " etc..Therefore, the research of casting alcohol-base paint has become current anxious to be resolved
One of the problem of.
Summary of the invention
Goal of the invention：The purpose of the invention is to provide a kind of casting alcohol-based coating, there is excellent viscosity, brush
Property, sag resistance, levelability, permeability, suspension, being coated with property and thixotropy.
The technical solution adopted by the present invention：A kind of casting alcohol-based coating, formula is by weight including following component：Fire resisting
10 ~ 25 parts of aggregate, 50 ~ 60 parts of carrier, 2 ~ 7 parts of binder, 10 ~ 15 parts of suspending agent, 8 ~ 49 parts of additives.
The refractory aggregate is one of silica flour, bauxite, zirconium English powder.
The suspending agent is organobentonite, lithium bentonite, attapulgite clay or nanoscale composite dispersed suspending agent.
The binder is phenolic resin or rosin.
The additives is defoaming agent, in coupling agent, wetting agent, levelling agent, nonionic surface active agent, preservative
It is one or more.
Beneficial effect：A kind of casting alcohol-based coating of the present invention, have excellent viscosity, brushability, sag resistance,
Levelability, permeability, suspension, being coated with property and thixotropy.
