Problems solved by technology

In the past, antistatic coatings mostly used carbon-based fillers (graphite, carbon black and carbon fiber), metal-based fillers (silver, copper, nickel, zinc and iron alloys, etc.), metal oxides, etc. as the main conductive fillers. Deep, not easy to disperse, unstable electrical properties, single variety, limited use, difficult to meet the decorative requirements of modern coatings

Embodiment 1

[0028] According to Example 1 in Table 1, according to the formula weight ratio, add deionized water into the dispersion tank, add dispersant, extender pigment, titanium dioxide, and bamboo charcoal powder under stirring, disperse at high speed for 30-40 minutes, and grind to a fineness of 30 μm to form a slurry material; put the grinding slurry into the paint mixing tank, add acrylic acid emulsion, silver-plated glass beads, quaternary ammonium methacrylate under medium speed stirring, and then add film-forming aids, defoamers, thickeners Rheological agent, stirring to adjust viscosity and pH value, that is, to prepare a white multifunctional antistatic water-based paint.

Embodiment 2

[0030] According to Example 2 in Table 1, according to the formula weight ratio, add deionized water into the dispersion tank, add dispersant, extender pigment, titanium dioxide, and bamboo charcoal powder under stirring, disperse at high speed for 30-40 minutes, and grind to a fineness of 30 μm to form a slurry Put the grinding slurry into the paint mixing tank, add styrene-acrylic emulsion, silver-plated glass microspheres, methoxy polyethylene glycol methacrylate under medium speed stirring, and then add film-forming aids, disinfectant Foaming agent, thickening rheological agent, stirring to adjust viscosity and pH value, that is, a white multifunctional antistatic water-based paint is prepared.

Embodiment 3

[0032] According to the formula weight ratio of Example 3 in Table 1, add deionized water into the dispersion tank, add dispersant, extender pigment, titanium dioxide, and bamboo charcoal powder under stirring, disperse at high speed for 30-40 minutes, and grind to a fineness of 30 μm to form a slurry material; pour the grinding slurry into the paint mixing tank, add silicone acrylic emulsion, silver-coated talc powder, quaternary ammonium methacrylate, water-based color paste under medium speed stirring, and then add film-forming aids and defoaming agents at a uniform speed agent, thickening rheological agent, stirring to adjust the viscosity and pH value, that is, a colorful multi-functional antistatic water-based paint is prepared.

Abstract

The invention relates to a preparation method of an infinite-color multifunctional antistatic water-based paint, which is composed of: 10%-30% of emulsion, 5%-20% of titanium dioxide, 15%-35% of extender pigment, and 3%-6% of bamboo charcoal powder , Conductive material 3%~10%, Permanent antistatic agent 5%~10%, Propylene glycol 2%~6%, Color paste 0%~10%, Auxiliary agent 3%~8%, Deionized water 15%~35% %; the conductive materials are silver-coated glass beads and silver-coated talc powder, and the permanent antistatic agent is (meth)acrylate copolymer containing quaternary ammonium salt and methoxy polyethylene glycol methacrylate copolymer; In addition to fully complying with the indicators stipulated in GB / T9756-2009, the infinite-color multifunctional antistatic water-based paint also has permanent antistatic properties, antibacterial disinfection, temperature regulation and environmental protection, and air purification. It can be widely used in computer rooms and classrooms. , offices, hospitals, factories and other interior wall coating that require antistatic requirements.

Description

technical field [0001] The invention relates to a preparation method of an antistatic paint, in particular to an infinite-color multifunctional antistatic water-based paint suitable for various indoors. Background technique [0002] Antistatic coatings are a group of special functional coatings with a volume resistivity within a certain range. With the development of modern technology, some places with walls and floors that require cleanliness and antistatic requirements, such as in electronic and electrical workshops, computer rooms, There are more and more applications in hospitals, printing factories, textile factories and pharmaceutical factories, and antistatic coatings are getting more and more extensive and in-depth attention. [0003] With the development of society and the improvement of living standards, people's awareness of environmental protection and health has been significantly enhanced, and the requirements for the comfort and safety of the living environmen...
