Building-material foaming board

Abstract

The invention belongs to the technical field of building materials, and specifically provides a building-material foaming board. The foaming board is prepared through the following steps: mixing 45 to 50 parts of polyvinyl alcohol and 150 to 160 parts of water so as to prepare a glue, placing the glue in a high-speed shearing machine, adding 130 to 150 parts of sulphoaluminate cement and 4 to 5 parts of an amine-alcohol rust inhibitor, carrying out high-speed shearing under stirring, wherein the shearing speed is 7000 to 9000 RPM and the shearing time is 12 to 15 min, transferring the obtained mixture into a high-speed stirrer, adding 13 to 15 parts of Kasong stone, 7 to 9 parts of lignocellulose, 1.5 to 1.8 parts of an inorganic aluminium salt water-proofing agent, 1.7 to 2.5 parts of magnesium aluminum silicate, 2.0 to 2.1 parts of acrylic acid rubber powder and 3 to 5 parts of a high-alumina cement foaming agent, carrying out stirring with a rotating speed of 1200 to 1600 r / min and a stirring time of 15 to 17 min, then adding 7 to 8 parts of PVA chopped strands, carrying out stirring with a rotating speed of 1200 to 1300 r / min and a stirring time of 12 to 15 min, discharging the obtained material into a mold, wherein the interior of the mold is fully and squarely stacked with steel wire cages with a volume of 10 dm3, subjecting the material in the mold to standing until curing and shaping are completed, taking the material out of the mold, and carrying out drying until the water content is 11%. The foaming board provided by the invention is used for solving the problems of poor safety, instability, and environmental pollution due to release of harmful gas in the process of heating for a halogen foaming board in the prior art.

Description

technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a building material foam board. Background technique [0002] The traditional halogen foam board has poor fire resistance, easy to catch fire, return to halogen, easy to carbonize and deform at high temperature, and release harmful gas during high temperature heating, which seriously affects its service life, safety performance and stability, and is prone to accidents , and the release of harmful gases will pollute the environment, creating a bad working environment for the staff. Contents of the invention [0003] The purpose of the present invention is to provide a building material foam board, which is used to solve the problems that the current halogen foam board is not safe, unstable, and will release harmful gas to pollute the environment during the heating process. [0004] For realizing above-mentioned technical purpose, the technical scheme that ...
