Description

The prescription of atomic lime putty

The present invention relates to pointing material before a kind of the priming, especially refer to automobile, lathe surface prime before the putty of pointing.

At present, automobile, in lathe and other the mechanical industry, pointing material commonly used is gesso (be with the alkyd ready-mixed paint base-material add the terra alba blending form) before the metallic surface spray-stain lacquer, but, because gesso solidifies slow (under 20 ℃ of temperature, need be through more than 24 hours, could solidify), poor adhesive force, difficulty adds mill and easy to crack, quality and working efficiency thereby influence is sprayed paint, in addition, also easy and other the various paint generation chemical reactions (as: nitro paint) of alkyd ready-mixed paint, therefore, suitability is restricted, and is especially inapplicable to the surperficial lacquer that sprays or be coated with of high-grade car crust.Although, recently having the people also to begin to manufacture experimently with the unsaturated polyester resin is the atomic lime putty (having another name called polymerization putty polyputty) of base-material, but, be main stuffing wherein with water-ground limestone (CaCO), polishing is hard, sticking power is poor again, solidifying agent adopts methylethyl ketone peroxide or benzoyl peroxide again, and curing performance is slow, preservation period is also short.

In view of this, the objective of the invention is to provide a kind of prescription of novel atomic lime putty, can help polishing, the mixture that strengthens sticking power, quick solidifying, long preservative period is arranged again.

The object of the present invention is achieved like this: it comprises host and solidifying agent, its host is base-material with the unsaturated polyester resin, it is characterized in that: the unsaturated polyester resin accounts for 20～30% by weight in the host, also have that styrene comprise 4～8%, methacrylic acid-β-Xiang ethyl ester account for 5～8%, N, the N-xylidene(s) accounts for 1%, Resorcinol accounts for 0.08%, phenylformic acid accounts for 2.5%, naphthoic acid cobalt accounts for the 0.5%(cobalt contents and be about 8%), talcum powder account for 50～60% and titanium dioxide account for 2.5%; Cyclohexanone peroxide in solidifying agent slurry accounts for 2%, permanent fixed yellow GG accounts for 0.5%.

The invention will be further described below in conjunction with embodiment.

Present embodiment comprises host and solidifying agent two parts, and host is base-material with 196# unsaturated polyester resin, adds strong solvent, initiator, promotor, cloudy poly-agent, dispersion agent, filler and stirs, grinds and form, and is the uniform thickness slurry of canescence; Solidifying agent is a base-material with the cycloethanone peroxide slurry, adding pigment stirs, grinds and form, be the orange starchiness, two parts's curing that is cross-linked with each other at normal temperatures, form hard solid, have quick solidifying, strong adhesion, easily polishing, smooth finish reach advantages such as high temperature resistant, oil resistant, shock-resistant, anti-nitro well, can be widely used in surperficial pointings such as automobile, lathe.

The prescription that present embodiment adopts is (by weight):

196# unsaturated polyester resin accounts for 30%
