Problems solved by technology

At present, most of the calcium silicate fiberboard release agents use diesel oil or lubricating oil or a mixture of diesel lubricating oil to release the mold, which has the problems of heavy odor, high cost, serious waste of resources and not conducive to environmental protection.
In addition, the use of emulsified paste as a release agent has problems such as high viscosity, difficulty in rolling coating, slow drying, and poor rust resistance.

Abstract

The invention discloses a calcium silicate fiberboard demolding agent, a preparation method and a use method thereof. The demolding agent comprises the following raw material components in parts by weight: 75-85 parts of a lubricating release agent, 10-20 parts of an emulsifier, 1.5-5 parts of an antirust agent, 1-5 parts of an antibacterial agent and 0.2-1 part of a stabilizer. According to the invention, the viscosity of the demolding agent can reach 2-4 CST, the dilution ratio is high, spray coating or roll coating is easy, and an oil film is evenly attached and rapidly dried; the demolding agent is rust-proof and non-corrosive to a template; after the calcium silicate fiberboard is cured and demolded, the surface is smooth, and edges and corners are complete; the surface of the template is clean, bright and rust-free, and the template can be continuously coated without being cleaned, so that the template can be quickly and repeatedly used, the yield and the working efficiency are greatly improved, and the labor intensity is reduced; and the demolding agent is low in odor, capable of well improving the working environment, good in environmental protection property and relatively low in cost.

Description

technical field [0001] The invention relates to a mold release agent, in particular to a calcium silicate fiber board mold release agent, a preparation method and a use method thereof. Background technique [0002] Calcium silicate fiberboard is a new generation of "green" building materials with excellent moisture-proof, fire-proof performance and environmental protection functions. It is a new type of building material that uses silicon powder and calcium powder as the main base material, natural wood fiber as the reinforcing material, and other auxiliary materials. Calcium silicate fiberboard is a white, hard new insulation material, which has the characteristics of light bulk density, high strength, small thermal conductivity, high temperature resistance, corrosion resistance, cutting and sawing, etc. It is widely used in electric power, metallurgy, petrochemical, Functions such as thermal insulation, fireproofing and sound insulation of equipment pipelines, walls and r...
