Description
Technical field
The present invention relates to technical field of coatings, particularly to the water borne soft-feel coating and preparation method thereof of a kind of Diamond Search.
Background technology
Being presently used for product surface and acting the elastic handfeel coating decorated with protective effect is oiliness elastic handfeel paint (elastic rubber paint), and due to the structure of oiliness elastic handfeel paint, the UV resistant performance causing oiliness elastic handfeel is very poor, can only be in indoor use；And easily " after-tacking ", after " after-tacking " is i.e. painting film production complete a period of time, again there occurs that film has similar not dry adhesion；Service life is typically at about 2 years.The shortcoming of above-mentioned oiliness elastic handfeel paint greatly limit the range of application of this series products.
Oiliness elastic handfeel paint is extremely sensitive to water, if the raw material moisture content of coating oiliness elastic handfeel paint is bigger, or when in wet weather and air, moisture content is higher, the problems such as paint film is moist often occurs in product.
The crocking resistance (RCA) of oiliness elastic handfeel paint is poor, and in the case of ensureing that product has preferable feel, RCA cannot be more than 50 times, and this performance also limit the use occasion of product.And traditional oil paint is inflammable and explosive, producing, transports, store the aspects such as use and all there is bigger potential safety hazard, and oil paint contains the toxic solvents such as stupid mostly, relatively big to harm, also bring more serious problem of environmental pollution.
The open a kind of oily wall coating of the patent of invention that notification number is CN101775251A of on 07 14th, 2010 bulletins, it is 30 containing percentage composition～the organosilicon modified crylic acid resin of 35% and pentanediol that percentage by weight is 15～20%, dipropylene glycol ethyl ether or dipropylene glycol ethyl ether acetate high boiling solvent, possibly together with 12～20% titanium dioxide, 10～20% Pulvis Talci, 4～6% silica filler, 0.5～the 714 type silicon class dispersants of 1%, 5.6～the zinc stearate of 6.0%, 6～the dimethyl carbonate of 7%, 2.5～the 345 type silicon class hand feeling agents of 3%, 1.2～the 469 type oiliness levelling agents of 1.5%, 0.5～the fine hair powder of 1% and 0.5～1% oiliness wax slurry；Though this kind of oily wall coating has good feel, but with high boiling organic solvent as solvent, volatile go out toxic organic compound, affect health and environmental pollution to a certain extent.It is thus desirable to the coating that a kind of volatile organic content is extremely low.
Summary of the invention
The technical problem to be solved in the present invention is to provide water borne soft-feel coating of a kind of Diamond Search and preparation method thereof, solve the product of coating oiliness elastic handfeel paint of the prior art mostly containing toxic solvents such as benzene, relatively greatly and more serious environmental pollution and oil product is brought to be only used for indoor harm, the problem that service life is shorter.
