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 unlimited-color multifunctional antistatic aqueous coating. The coating comprises 10-30% of an emulsion, 5-20% of titanium dioxide, 15-35% of an extender pigment, 3-6% of bamboo charcoal powder, 3-10% of a conductive material, 5-10% of a permanent antistatic agent, 2-6% of propylene glycol, 0-10% of a color paste, 3-8% of an assistant, and 15-35% of deionized water, wherein the conductive material is silvered glass microspheres and silvered talcum powder, and the permanent antistatic agent is a (meth)acrylate copolymer and methoxy polyethylene glycol methylacrylate copolymer containing a quaternary ammonium salt. The unlimited-color multifunctional antistatic aqueous coating completely accords with all indexes prescribed by GB/T9756-2009, has permanent antistatic performance, has the efficacy of preventing bacteria and disinfecting, adjusting the temperature and protecting environment, and purifying air, and can be widely applied in coating of interior walls having antistatic requirements of machine rooms, classrooms, office rooms, hospitals and factories.

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...
