Problems solved by technology

[0002] The existing anti-static non-flammable terrazzo has the problems of unsustainable performance and high repair rate after long-term use, and its anti-static materials and non-flammable aggregates have relatively large defects in physical and chemical properties
First of all, the conductive powder (such as graphite, etc.) that undertakes the anti-static function is easily oxidized in the air and loses its conductive function. Under the catalysis of alkaline media such as cement, the oxidation-reduction reaction is accelerated. Generally, the anti-static test will take 10-16 months. Does not meet national standards
Secondly, the dolomite used in non-pyrophoric aggregates is light and brittle. The principle of non-pyrophoric use is to use this characteristic. In practical applications, even if there is a slight friction and collision, the ground will crack and sand and cause damage. , its non-fire function is also lost

Abstract

The invention provides an antistatic misfire graphene millstone. The antistatic misfire graphene millstone comprises, by weight, 90-100 parts of ordinary Portland cement, 2-5 parts of graphene, 3-5 parts of polycarboxylate, 20-40 parts of a pigment, 3-5 parts of an ethylene-vinyl acetate copolymer, 2-5 parts of oyster shells, 0.5-0.7 part of dispersible latex powder, 2-5 parts of sodium acetate and 180-200 parts of dolomite. The antistatic misfire graphene millstone has the advantages of stable electric conductivity, high compressive strength, good wear resistance and good misfire property.

Description

technical field [0001] The invention belongs to the field of grinding stones, in particular to a graphene antistatic and non-flammable grinding stone. Background technique [0002] The existing antistatic non-flammable terrazzo has the problems of unsustainable performance and high repair rate after long-term use, and its antistatic materials and non-flammable aggregates have relatively large defects in physical and chemical properties. First of all, the conductive powder (such as graphite, etc.) that undertakes the anti-static function is easily oxidized in the air and loses its conductive function. Under the catalysis of alkaline media such as cement, the oxidation-reduction reaction is accelerated. Generally, the anti-static test will take 10-16 months. Does not meet national standards.
