Problems solved by technology

[0003] With the progress of society, the development of economy, and the advancement of science and technology, human beings have higher and higher requirements for the decorative effect of indoor ceilings and walls. Materials such as decorative plates, gypsum boards, and calcium silicate boards have high water absorption. The surface strength is low, and it is easy to cause yellowing, peeling, hollowing, cracking and other phenomena when scraping putty in batches. Therefore, the development of an anti-yellowing interface agent has great social and economic benefits

Embodiment 1

[0014] 200 kg of water, 3 kg of hydroxyethyl cellulose, 4 kg of dispersant, 1.5 kg of defoamer, 1.5 kg of bactericide, 20 kg of antifreeze, 1 kg of regulator, 60 kg of calcium carbonate, 40 kg of titanium dioxide, quartz 180 kg of sand, 22.5 kg of film-forming aids, and 460 kg of acrylic emulsion.

[0015]

[0016] When preparing, first put the above water into the mixing tank, slowly add hydroxyethyl cellulose under low-speed stirring, stir for 20 minutes, then slowly add dispersant, defoamer, bactericide, antifreeze, regulator, and stir for 15 minutes at low speed. Minutes, then slowly put calcium carbonate, titanium dioxide, and quartz sand into the mixing tank, stir at high speed for 30 minutes, then put in film-forming aids and acrylic acid emulsion, stir at low speed for 15 minutes, and take out the materials to obtain the new anti-yellowing interface agent.

Embodiment 2

[0018] Take 150 kg of water, 4 kg of hydroxyethyl cellulose, 3 kg of dispersant, 2 kg of defoamer, 1 kg of bactericide, 22 kg of antifreeze, 0.5 kg of regulator, 90 kg of calcium carbonate, 60 kg of titanium dioxide, quartz 160 kg of sand, 25 kg of film-forming aids, and 480 kg of acrylic emulsion.

[0019] When preparing, first put the above water into the mixing tank, slowly add hydroxyethyl cellulose under low-speed stirring, stir for 20 minutes, then slowly add dispersant, defoamer, bactericide, antifreeze, regulator, and stir for 15 minutes at low speed. Minutes, then slowly put calcium carbonate, titanium dioxide, and quartz sand into the mixing tank, stir at high speed for 30 minutes, then put in film-forming aids and acrylic acid emulsion, stir at low speed for 15 minutes, and take out the materials to obtain the new anti-yellowing interface agent.

Embodiment 3

[0021] Take 170 kg of water, 4.6 kg of hydroxyethyl cellulose, 4.5 kg of dispersant, 2.5 kg of defoamer, 2 kg of bactericide, 25 kg of antifreeze, 0.8 kg of regulator, 70 kg of calcium carbonate, 45 kg of titanium dioxide, quartz 170 kg of sand, 27 kg of film-forming aids, and 470 kg of acrylic emulsion.

[0022] When preparing, first put the above water into the mixing tank, slowly add hydroxyethyl cellulose under low-speed stirring, stir for 20 minutes, then slowly add dispersant, defoamer, bactericide, antifreeze, regulator, and stir for 15 minutes at low speed. Minutes, then slowly put calcium carbonate, titanium dioxide, and quartz sand into the mixing tank, stir at high speed for 30 minutes, then put in film-forming aids and acrylic acid emulsion, stir at low speed for 15 minutes, and take out the materials to obtain the new anti-yellowing interface agent.

Abstract

The invention relates to an interface agent, especially to an anti-yellowing interface agent. The anti-yellowing interface agent comprises components of hydroxyethyl cellulose, a dispersant, an antifoaming agent, a bactericide, an antifreeze agent, a conditioning agent, calcium carbonate, titanium dioxide, quartz sand, an acrylic acid emulsion and the like. The interface agent provided by the invention can effectively resist alkali releasing and yellowing of various wood-based panels, plasterboards, calcium silicate boards and the like with large water absorption and low surface strength, has good bidirectional softness, can be firmly combined with a putty layer, and can be used to prevent the putty layer from peeling, hollowing, cracking and the like.

Description

[0001] technical field [0002] The invention relates to an interface agent, in particular to an anti-yellowing interface agent. Background technique [0003] With the progress of society, the development of economy, and the advancement of science and technology, human beings have higher and higher requirements for the decorative effect of indoor ceilings and walls. Materials such as decorative plates, gypsum boards, and calcium silicate boards have high water absorption. The surface strength is low, and it is easy to cause yellowing, peeling, hollowing, cracking and other phenomena when scraping the putty. Therefore, the development of an anti-yellowing interface agent has great social and economic benefits. Contents of the invention [0004] The object of the present invention is to provide an anti-yellowing interface agent that can effectively resist yellowing, peeling, hollowing, and cracking of various base materials on indoor walls, and keep walls from yellowing for...
