Problems solved by technology

[0003] However, the lack of toughness of the existing calcium silicate board products makes the calcium silicate board fragile and easy to break; and the loss of raw materials for making calcium silicate board is large, and raw materials such as cement are lost during the production process, which causes The increased concentration of back slurry will seriously affect the quality of the finished product of calcium silicate board

Abstract

The invention provides a preparation method of a special reinforcing aid for construction and building materials, wherein the preparation method comprises the steps: adding 20% sodium chloride duringpolyacrylamide preparation, preparing a solution, using an iron medicine dissolving tank, controlling the water temperature of the solution to be 20-30 DEG C, and controlling the stirring time to be 60-90 minutes and the rotating speed to be 200-400 revolutions per minute. Through oxidation reaction and hydrolysis chemical behaviors of iron ions contained in water, molecular bonds of residual polyacrylamide in flocculated water are broken, reduction of the elasticity modulus of a polyacrylamide solution is accelerated, the wire drawing diameter of the polyacrylamide solution is reduced, and the wire drawing time is shortened; finally, the chain entanglement opportunity among molecules of polyacrylamide is reduced, the entanglement degree is weakened, the molecules become easy to flow, theviscosity value of a silicic acid cover plate can be reduced after the polyacrylamide is added into a calcium silicate plate as a building material reinforcing aid, the toughness of the calcium silicate plate is improved, and the problems that the calcium silicate plate is fragile and easy to break are solved; the loss of raw materials such as cement in the production process is reduced, so that the returned slurry concentration is reduced, and the quality of the carbonic acid cover plate is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of reinforcing aids, in particular to a preparation method of special reinforcing aids for construction and building materials. Background technique [0002] At present, in related technologies, calcium silicate board is a new type of green and environmentally friendly building material. In addition to the functions of traditional gypsum board, it also has the advantages of superior fire resistance, moisture resistance, and long service life. It is widely used in the ceiling of industrial and commercial engineering buildings. And partition walls, home decoration, furniture linings, billboard linings, warehouse sheds, network floors, and tunnels and other indoor projects. [0003] However, the lack of toughness of the existing calcium silicate board products makes the calcium silicate board fragile and easy to break; and the loss of raw materials for making calcium silicate board is large, and ...
