Problems solved by technology

However, it also has poor film-forming properties and poor crack resistance; at the same time, due to insufficient diffusion between latex particles, the internal cross-linking property is poor, and it is easy to form pulverization and powder removal; in addition, the poor cross-linking degree makes its hardness low and easy to Scratches; In addition, there are technical defects such as easy cracking

Abstract

The invention discloses water-based mirror back paint and a processing technology thereof. The water-based mirror back paint is prepared from the following raw material components in parts by weight: 50 to 70 parts of styrene-acrylic emulsion with a shell-core structure, 10 to 20 parts of filler, 2 to 10 parts of deionized water, 0.3 to 0.6 part of a dispersing agent, 0.2 to 0.4 part of a wetting agent, 0.1 to 0.3 part of a defoaming agent, 2 to 8 parts of a film-forming agent, 1 to 5 parts of color paste, 0.1 to 0.2 part of a sterilizing agent, 0.5 to 1 part of a pH value regulator and 0.1 to 0.15 part of a thickening agent. The water-based mirror back paint has the beneficial effects that carbon nanotubes are introduced into the core of the shell-core-structured styrene-acrylic emulsion, so the mechanical capacity of a formed paint film is effectively enhanced, and crack resistance is improved; and dimethylaminoethyl methacrylate and 3-isopropyl-dimethyl benzyl isocyanate are introduced into the shell of the shell-core-structured styrene-acrylic emulsion, so the film-forming property of high-concentration styrene-acrylic in the application of the water-based mirror back paint is ensured, crosslinking is increased, the phenomenon of pulverization is inhibited, and crosslinking toughness is increased through combination with 1,4-butanediol diglycidyl ether in the film-forming agent.

Description

technical field [0001] The invention relates to the technical field of water-based mirror back paint, in particular to a water-based mirror back paint and a processing technology thereof. Background technique [0002] Traditional mirror back paint uses organic solvents such as benzene, toluene, and xylene as diluents or dispersion media, so that it produces high VOC content during production and application, has a large pungent odor, and is prone to environmental pollution. Pollution can cause serious harm to human health. Therefore, out of the people-oriented development concept and the green development of environmental protection, people are more inclined to choose water-based mirror back paint to meet the increasingly stringent environmental laws and regulations. However, compared with oil-based mirror back paint, water-based mirror back paint cannot meet the requirements in terms of film formation due to the limitation of water-based materials, and cannot replace oil-b...
