Embodiment 1

[0028] (1) Grinding each component: 44 parts by weight of waste powder of optical fiber preform, 17 parts by weight of quartz sand, 13 parts by weight of wollastonite powder, 13 parts by weight of dispersible latex powder, 3 parts by weight of starch ether, Put 8 parts by weight of titanium dioxide into a powder grinder for mixing and grinding, and pass through a 300-mesh sieve after grinding to obtain a mixed powder.

[0029] (2) Preparation of mixed powder: Add 2 parts by weight of weighed nano-titanium dioxide into the mixed powder, then put it into a mixer and stir evenly to obtain an environment-friendly interior wall paint.

[0030] Add the prepared environment-friendly interior wall paint into 200 parts by weight of clear water, stir it and put it into the spray gun. It was observed that the coating had good sag resistance. After thorough drying, the surface has good flatness, fineness and smoothness, and there is no obvious scratch after being lightly polished with wa...

Abstract

The invention discloses an environment-friendly interior wall coating with waste generated during production of optical fibers as a base material. The environment-friendly interior wall coating is prepared from, by weight, 40-50 parts of pretreated optical fiber performing bar waste powder, 15-20 parts of quartz sand, 12-15 parts of wollastonite powder, 10-15 parts of dispersible latex powder, 1.5-2.5 parts of nanometer titania, 2-3 parts of starch ether and 8-15 parts of titanium oxide pigment, wherein the optical fiber performing bar waste powder is calcined for 20-60 min at 500-700 DEG C tobe pretreated, and TiO2 with visible-light photocatalytic activity is adopted for nanometer titania. The environment-friendly interior wall coating has the advantages of being capable of purifying air, good in paint film performance, small in construction difficulty and the like, and the problems that the environment is polluted when optical fiber waste is thrown about and an interior wall coating does not have functionality and environment protection performance simultaneously are greatly solved.

Description

technical field [0001] The invention belongs to the field of architectural coatings, and in particular relates to an environment-friendly interior wall coating prepared by using waste powder of optical fiber prefabricated rods. Background technique [0002] At present, the most widely used interior wall coatings in my country's market are latex paint and diatom mud. Although latex paint has the advantages of light weight, non-combustibility, convenient maintenance and renovation, and low energy consumption in production and application, because there are often some residual monomers in the base synthetic resin emulsion, it will inevitably bring some volatile organic compounds. Some latex paints contain volatile organic solvents, which will cause some indoor air pollution, which is very harmful to human health. However, diatom mud, another environmentally friendly inorganic coating widely used in the market, has extremely low content of volatile organic compounds and has the...
