Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the current acrylic paint relies solely on the action of chemical groups, loses the sticking effect, falls off, remains after aging, and causes surface pollution, and provides a microporous acrylic paint, which forms a microporous acrylic paint on the surface after curing. Holes for enhanced and longer sticking time

Embodiment 1

[0026] Add 1 part of glyceryl tristearate dispersant and 20 parts of sodium bicarbonate foaming agent to 20 parts of water, and disperse evenly with a high-speed mechanical disperser at a stirring speed of 1200 rpm for 30 minutes to prepare a foaming agent emulsion.

[0027] In 40 parts of acrylic resin, add 15 parts of titanium dioxide, 3 parts of white carbon black, and 1 part of glyceryl tristearate dispersant, disperse evenly with a high-speed disperser, stir at a speed of 2000 rpm, and stir for 30 minutes. The foaming agent emulsion is added slowly under high-speed stirring. During the dispersion process, the dispersion temperature should not exceed 50°C.

[0028] Wherein, the acrylic resin can be a product whose hardness is less than 2H after curing.

[0029] Use PET as the base material, apply it on the base material, and use the steel plate as the paste object. The measured 180°peel strength is 13g / inch, and there is no change after 24 hours of UV (wavelength 340nm) i...

Embodiment 2

[0031] (1) Add 1 part of glyceryl tristearate dispersant and 10 parts of azo compound foaming agent to 20 parts of water, disperse evenly with a high-speed mechanical disperser, stir at a stirring speed of 1200 rpm, and stir for 30 minutes to make a foam agent emulsion.

[0032] Add 16 parts of titanium dioxide, 2 parts of white carbon black, and 1 part of N,N'-hexylene bisstearamide dispersant to 50 parts of acrylic water-based pressure-sensitive adhesive, and disperse evenly with a high-speed disperser, stirring speed 2000rpm, stirring time After 30 minutes, slowly add the foaming agent emulsion prepared therein under high-speed stirring. During the dispersion process, the dispersion temperature should not exceed 50°C.

[0033] Among them, the preparation method of the acrylic water-based pressure-sensitive adhesive: add the solvent, part of the mixed monomers, and the initiator into the reaction device, and add the remaining mixed monomers dropwise when the temperature rea...

Abstract

The invention discloses a microporous acrylic paint and a preparation method thereof. The paint comprises the components of, by weight, 40-60 parts of an acrylic elastomer, 5-30 parts of titanium dioxide, 1-20 parts of a foaming agent, 1-2 parts of a dispersing agent, 1-20 parts of water, and 1-5 parts of white carbon black. When the paint is set, an acrylic coating material providing a physical adsorption manner can be formed. When the coating contacts a flat surface and is slightly pressed, residual air in the micro-pores are discharged, and certain negative pressure is generated, such that the bonding of other interfaces which do not completely contact the flat surface can be promoted. Therefore, the entire coating can be completely bonded with the flat surface. The paint provided by the invention has the characteristics of low cost and aging resistance, and can be repeatedly used.

Description

technical field [0001] The invention relates to the field of acrylic paint, and more specifically relates to a microporous acrylic paint and a preparation method thereof. Background technique [0002] At present, the materials used as surface protection film include acrylic acid, epoxy resin, polyurethane, silicone materials and hybrid materials, etc. Among them, acrylic acid is an important material in the traditional coating industry, with good adhesion, low cost and easy manufacture. Take and other features. These materials are semi-cured by heat, light and other curing methods, have a certain chemical viscosity, and can be pasted on the surface to be protected to play a protective role. However, since these adsorption effects are derived from the force of chemical groups, these chemical groups will lose their sticking effect after aging, resulting in falling off, or even remaining, and polluting the surface. The existing acrylic protective films basically use chemical ...
