Abstract

The invention belongs to the technical field of building materials and particularly relates to a cement fiber board additive. The cement fiber board additive comprises the following raw materials in parts by weight: 0.05-1 part of sorbitan fatty acid ester, 1-3 parts of sodium hydroxide, 0.025-0.5 part of hexafluoroacetylacetone, 0.025-1 part of silicone oil, 0.5-5 parts of calcium stearate, 1-5 parts of cellulose ether and 1-10 parts of a plant cellulose film. According to the cement fiber board additive, the unit weight and the cost of a cement fiber board can be lowered, and the prepare cement fiber board is unlikely to crack and has good water resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cement fiberboard additive. Background technique [0002] At present, existing fiberboard products that use cement as a bonding agent, such as wooden cement particleboard, have a high density and are limited in use. The adhesives used in the production process of cement fiberboard are mostly resins or isocyanates, etc. During the production process, harmful gases are likely to be generated or production costs are high. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the invention provides a cement fiberbo...
