Abstract
The invention provides a preparation method of acid and alkali resistant acrylic lacquer. The preparation method of the acid and alkali resistant acrylic lacquer comprises the following steps: carrying out copolymerization on 1226 parts by weight of butyl acrylate and 223 parts of maleic anhydride, so that a first component is obtained; carrying out reaction on 68.6 parts by weight of diisopropanol amine, 38.5 parts by weight of isobutyraldehyde and 94.3 parts by weight of polyisocyanates, so that a second component is obtained; carrying out polymerization on 3000 parts of 3-methylacrylic acid propyl trimethoxy silane, 600 parts of methyl methacrylate and 400 parts of butyl acrylate, so that a third component is obtained; grinding the first component, the second component and the third component, and uniformly mixing, so that the acid and alkali resistant acrylic lacquer is obtained. The acid and alkali resistant acrylic lacquer can be coated on a coloured or undercoated base material just like common lacquer, has good acid and alkali corrosion resistance, can resist 6% sulphuric acid, 6.1mol/L potassium hydroxide and methyl ethyl ketone and can be applied to a table board of a laboratory.
Description
Technical field
The present invention relates to the making method of coating, be specifically related to a kind of making method of acrylic varnish of acid and alkali-resistance.
Background technology
Current varnish acid and alkali-resistance ability is all bad, or acidproof separately, and what have is alkaline-resisting separately, but does not also have a kind of varnish can be simultaneously to the equal endurance of soda acid ability.
Summary of the invention
The object of this invention is to provide a kind of making method of acrylic varnish of acid and alkali-resistance, solve one or more problem of the prior art.
According to an aspect of the present invention, providing a kind of making method of acrylic varnish of acid and alkali-resistance, is that the butyl acrylate of 1226 parts and the MALEIC ANHYDRIDE copolymerization of 223 parts obtain the first component by parts by weight; Be that the diisopropanolamine (DIPA) of 68.6 parts, the isobutyric aldehyde of 38.5 parts, the polyisocyanates reaction of 94.3 parts obtain second component by parts by weight; Be that the 3-methacrylic acid propyl trimethoxy silicane of 3000 parts, the methyl methacrylate of 600 parts, the butyl acrylate copolymerization of 400 parts obtain the 3rd component by parts by weight; The first component, second component, the 3rd component are mixed to the acrylic varnish that obtains acid and alkali-resistance after grinding.
The invention provides a kind of making method of acrylic varnish of acid and alkali-resistance, the modified acroleic acid varnish of making is identical with general varnish usage, can be coated on coloured or have on the base material of priming paint, the present invention has good acid-alkali-corrosive-resisting ability, sulfuric acid, 6.1mol/L potassium hydroxide and the methylethylketone of ability 6%, can apply to the table top in laboratory.
Specific implementation method
The invention provides a kind of making method of acrylic varnish of acid and alkali-resistance, the MALEIC ANHYDRIDE copolymerization of the butyl acrylate of 1226g and 223g is obtained to the first component; The polyisocyanates reaction of the isobutyric aldehyde of the diisopropanolamine (DIPA) of 68.6g, 38.5g, 94.3g is obtained to second component; The butyl acrylate copolymerization of the methyl methacrylate of the 3-methacrylic acid propyl trimethoxy silicane of 3000g, 600g, 400g is obtained to the 3rd component; The first component, second component, the 3rd component are mixed to the acrylic varnish that obtains acid and alkali-resistance after grinding.
The invention provides a kind of making method of acrylic varnish of acid and alkali-resistance, the modified acroleic acid varnish of making is identical with general varnish usage, can be coated on coloured or have on the base material of priming paint, the present invention has good acid-alkali-corrosive-resisting ability, sulfuric acid, 6.1mol/L potassium hydroxide and the methylethylketone of ability 6%, can apply to the table top in laboratory.
More than statement is only optimal way of the present invention, it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, within these also should be considered as protection scope of the present invention.
