Problems solved by technology

The slender particles are connected by weak chemical bonds to form a network structure, which is easily destroyed by external force. The inorganic thixotropic agent is LBCB-1 of Shijiazhuang Langbo Chemical, which is widely used in the construction and coating industries. The existing suspension thixotropic agent The amount of cellulose that needs to be used is relatively high, which makes the production cost relatively high, the water retention effect is relatively poor, and it is easy to precipitate, the storage period is not long, and it is difficult to meet the needs of building construction

Abstract

The invention discloses a preparation method of a suspension thixotropic agent. The following raw materials in parts by weight are used: 5-10 parts of magnesium aluminum silicate, 1-2 parts of natural lithium montmorillonite, 3-5 parts of cellulose thickening powder, 6-14 parts of composite mortar, 1-2 parts of a ceramic tile binding agent, 1-2 parts of a cement color gap filling agent, 3-5 parts of agar powder and 30-60 parts of water. The preparation method disclosed by the invention has the advantages that by adopting the magnesium aluminum silicate, an alkali-swelled organic thickening agent can be reduced, the usage amount of cellulose and the cost can be reduced, and a certain synergistic water retaining effect is realized; by adopting the natural lithium montmorillonite, a colloid can be formed or swelling is full, so that the viscosity of the coating is enhanced; and a solvated thin film is formed on the surface of a refractory base material or a stereoscopic reticular structure is formed, so that the refractory base material is supported and prevented from sinking, the suspension stability of the coating is improved, and further the coating has excellent thixotropy. The suspension thixotropic agent has stable viscosity, difficulty in precipitation, long storage period and relatively low production cost and is applicable to extensive popularization.

Description

technical field [0001] The invention relates to the technical field of thixotropic agents, in particular to a preparation method of a suspended thixotropic agent. Background technique [0002] When the grease is sheared, the consistency becomes smaller, and when the shear is stopped, the consistency increases again, that is, thixotropy. Thixotropy also known as thixotropy. It is a reversible sol phenomenon that occurs when the gel is subjected to mechanical forces such as vibration and compression. It was discovered by Freundlich (H.M.F. Freundlich 1928). The slender particles are connected by weak chemical bonds to form a network structure, which is easily destroyed by external force. The inorganic thixotropic agent is LBCB-1 of Shijiazhuang Langbo Chemical, which is widely used in the construction and coating industries. The existing suspension thixotropic agent The amount of cellulose that needs to be used is relatively high, which makes the production cost relatively ...
