Abstract
The present invention provides a varnish formula, wherein components in the formula comprise, by mass, 55-63% of a 3060 resin, 20-25% of a 3901 resin, 2-4% of butyl ester, 10-15% of xylene, 1-3% of butanol, 0.03-0.05% of a 331 auxiliary agent, 0.20-0.30% of a 358 auxiliary agent, and 2-4% of an epoxy resin. According to the present invention, the 3060 resin (hydroxyl acrylic resin) is adopted as the raw material, and has characteristics of high weathering resistance, no ultraviolet ray absorption, melting resistance even under outdoor exposure weather, and varnish cross-linking density increase so as to increase varnish hardness and enhance varnish solubility resistance; and the epoxy resin is adopted, such that the varnish can achieve a corrosion resistance purpose, and adhesion of the varnish can be increased. The produced varnish has good use performances.
Description
Technical field
The present invention relates to a kind of varnish, particularly relate to a kind of formula and preparation method of varnish.
Background technology
At present, varnish is as a kind of Clear paint, because of its good luster, become mould fast, and can form smooth film after being coated in the body surface drying, demonstrates the original texture of object plane, thereby welcome widely.But traditional varnish poor heat resistance, can produce the phenomenon of thawing in hot summer, this brings great inconvenience to industrialized application, and varnish also will brush after melting repeatedly, has both affected attractive in appearancely, wastes raw material again.And the varnish be coated on furniture is easily mouldy, and sticking power is poor, easily peels off, thereby caused the damage to article.
Summary of the invention
The formula that the purpose of this invention is to provide a kind of varnish solves traditional varnish poor heat resistance, can produce the phenomenon of thawing in hot summer, this brings great inconvenience to industrialized application, and also will repeatedly brush after the varnish thawing, both affected attractive in appearancely, wasted raw material again.And the varnish sticking power be coated on furniture is poor, easily peels off, thereby caused the problem to the damage of article.
Technical solution of the present invention is: the invention discloses a kind of formula of varnish, the mass percent of each component is:
3060 resins 55 ~ 63%
3901 resins 20 ~ 25%
Butyl ester 2 ~ 4%
Dimethylbenzene 10 ~ 15%
Butanols 1 ~ 3%
331 auxiliary agents 0.03 ~ 0.05%
358 auxiliary agents 0.20 ~ 0.30%
Epoxy resin 2 ~ 4%
Further improve and be: the composition by following concrete mass percent forms:
3060 resins 57.40%
3901 resins 21.15%
Butyl ester 3.08%
Dimethylbenzene 13.22%
Butanols 1.77%
331 auxiliary agents 0.04%
358 auxiliary agents 0.26%
Epoxy resin 3.08%
A kind of method for preparing acrylic varnish according to above-mentioned formula, concrete steps are as follows:
Step 1: butyl ester, butanols, dimethylbenzene are added to stirring tank, and controlling the stirring tank temperature is 30 ~ 40 ℃, stirs 30 ~ 40 minutes, obtains mixing solutions;
Step 2: 3060 resins, 3901 resins and epoxy resin are added in the mixing solutions of step 1 gained, and again stir 30 ~ 40 minutes with stirring tank, it is stirred;
Step 3: go out still in high speed dispersor, in 30 ~ 40 ℃, carry out strong stirring;
Step 4: stir on limit, and limit slowly adds 358 auxiliary agents, 331 auxiliary agents;
Step 5: with dispersion machine, stir, viscosimetric;
Step 6: the discharging packing, survey the physical and mechanical propertiess such as solid content, sticking power, snappiness, the qualified rear packing warehouse-in of indices.
Beneficial effect of the present invention: it is Hydroxylated acrylic resin that the present invention adopts 3060 resins, as raw material, has high-weatherability, do not absorb ultraviolet ray, even the weather be exposed to the sun out of doors also is difficult for melting, and can improve the cross-linking density of varnish, thereby the hardness of varnish is improved, and anti-dissolubility strengthens.Adopting again 3901 resins is the unsaturated polyester ester epoxy resin, and adds in addition epoxy resin in production formula again, can make varnish reach the rot-resistant purpose, and improves the sticking power of varnish.And make varnish there is higher chemicals-resistant, resistance to salt water and alkali-resistivity.Therefore, the varnish of producing has good use properties, is suitable for the application of industrialization each side.
