Fireproof wall paint and preparation method thereof

Abstract

The invention provides fireproof wall paint. The fireproof wall paint comprises raw materials in parts by weight as follows: 30-40 parts of water, 0.5-1 part of a dispersing agent, 0.3-0.5 parts of a wetting agent, 0.5-1 part of a defoaming agent, 0.5-1 part of a preservative, 1-2 parts of an anti-freezing agent, 0.5-1 part of a scrubbing-resistant agent, 1-2 parts of quartz powder, 10-15 parts of modified talcum powder, 10-20 parts of titanium dioxide, 0.2 parts of a PH (potential of hydrogen) regulator, 1 part of a coalescing agent, 0.5-1 part of a thickening and flattening agent and 25-35 parts of a styrene-acrylic emulsion. The invention further provides a preparation method of the fireproof wall paint. The preparation method comprises steps as follows: the dispersing agent, the wetting agent, the defoaming agent, the preservative, the anti-freezing agent, the scrubbing-resistant agent, the quartz powder, the modified talcum powder and titanium dioxide are added to water sequentially and stirred uniformly at the stirring speed of 1,000 revolutions / min, the mixture is ground to reach the fineness of 25-35 mu m, the PH regulator, the coalescing agent, the thickening and flattening agent and the styrene-acrylic emulsion are added, the viscosity of the mixture is adjusted to 110 KU, the contrast ratio is 0.95, the PH value is 7-8, and a wall paint product is obtained. The wall paint has excellent stability.

Description

technical field [0001] The invention belongs to the technical field of wall coatings, and in particular relates to a firewall top coating and a preparation method thereof. Background technique [0002] With the further development of my country's economic construction, my country's architectural coatings have very broad development potential and promotion market. my country's wall coatings have a wide range of applications and a large demand, but general wall coatings have poor anti-fouling, wear-resistant and abrasion resistance, low hardness, easy aging of the coating film, short service life, and poor stability of general wall coatings. The fire performance is not good, so it cannot be used in some special fields. Contents of the invention [0003] In order to solve the above problems, the present invention provides a firewall finish, which is composed of the following raw materials in parts by weight: 30-40 parts of water, 0.5-1 part of dispersant, 0.3-0.5 part of wett...
