Embodiment 1

[0020] A cement-based self-leveling antistatic floor material, comprising the following components calculated by weight ratio: 15 parts of aluminate cement, 20 parts of ordinary Portland cement, 3 parts of fly ash, 1 part of slag, cooked 1 part of gypsum, 1 part of ethylene / vinyl acetate copolymer latex powder, 0.4 part of silicone defoamer, 1 part of polycarboxylate superplasticizer, 56.05 parts of quartz sand, copper fiber (diameter 5 μm, length 0.5 cm ) 0.05 parts, copper powder (200 mesh) 1.5 parts. Weigh each component according to the weight ratio, add water and stir evenly after mechanical mixing; then pour the ground, self-leveling molding, and solidify into a ground material. The weight ratio of floor material to water is 1:0.15. The performance test is shown in Table 1.

Embodiment 2

[0022] A cement-based self-leveling antistatic floor material, comprising the following components calculated by weight ratio: 25 parts of aluminate cement, 10 parts of ordinary Portland cement, 1 part of fly ash, 3 parts of slag, cooked 3 parts of gypsum, 0.5 part of vinyl acetate / ethylene tertiary carbonate copolymer latex powder, 0.8 part of polyacrylic acid defoamer, 0.5 part of polycarboxylate superplasticizer, 54.0 parts of quartz sand, stainless steel fiber (diameter 30 μm, length 2cm ) 0.2 parts, stainless steel powder (800 mesh) 2 parts. After weighing and mixing according to the above weight ratio, add water and stir evenly before construction and use. The weight ratio of floor material to water is 1:0.25. The performance test is shown in Table 1.

Embodiment 3

[0024] A cement-based self-leveling antistatic floor material, comprising the following components calculated by weight ratio: 20 parts of aluminate cement, 20 parts of ordinary Portland cement, 2 parts of fly ash, 2 parts of slag, cooked 2 parts of gypsum, 0.8 part of acrylic polymer latex powder, 0.5 part of silicone defoamer, 0.5 part of polycarboxylate superplasticizer, 49.1 parts of quartz sand, 0.1 part of carbon fiber (diameter 10 μm, length 1 cm), conductive Muscovite (600 mesh) 3 parts. After weighing and mixing according to the above weight ratio, add water and stir evenly before construction and use. The weight ratio of floor material to water is 1:0.20. The performance test is shown in Table 1.

Abstract

The invention relates to the technical field of building materials, and aims at providing a cement-based self-leveling antistatic terrace material. The cement-based self-leveling antistatic terrace material comprises, by weight, 15-25 parts of aluminate cement, 10-20 parts of ordinary portland cement, 1-3 parts of fly ash, 1-3 parts of slag, 1-3 parts of calcined gypsum, 0.5-1 part of re-dispersible latex powder, 0.4-0.8 parts of an antifoaming agent, 0.5-1 part of a water reducer, 49.10-56.05 parts of quartz sand, 0.05-0.2 parts of a conductive fiber filler and 0.5-3 parts of a conductive powdery filler. Cooperative use of the fiber conductive filler and the powdery conductive filler in the invention facilitates formation of a conductive network structure, reduces the use amount of the conductive filler and reduces the electric resistance of the terrace material; the small use amount of the conductive filler has small influences on the fluidity and the mechanical performances of the self-leveling terrace material and has no influences on engineering use; and use of the conductive fiber material improves the shrinkage crack resistance of the terrace material.

Description

technical field [0001] The invention relates to a formula of a cement-based self-leveling antistatic floor material, which belongs to the field of building materials. Background technique [0002] Floor materials have a wide range of applications, and their functional requirements are getting higher and higher, and antistatic function is one of them. At present, the antistatic floor is mainly epoxy antistatic floor, which is composed of solvent-based epoxy resin, curing agent, and conductive filler. Due to the use of organic solvents as diluents, there are disadvantages such as polluting the environment and damaging human health. Moreover, the environment Oxygen antistatic floor also has defects such as poor surface wear resistance, short service life, and large amount of conductive fillers. [0003] Cement-based self-leveling floor is composed of cementitious material, fine aggregate, filler and additives, etc. It has good fluidity after mixing with water, and it can be au...
