Embodiment 1
[0010] The invention is an improved cement anti-crack modifier, which is made of the following raw materials in parts by weight:
[0011] 2.5 parts of lead salt stabilizer, 3.3 parts of camellia saponin, 6.5 parts of butane tetracarboxylic acid, 7 parts of kaolin, 1.8 parts of silicon oxide, 2.2 parts of glycerol triglyceride, 2.7 parts of polyvinyl acetate and 3.6 parts of molybdenum red share.
Embodiment 2
[0013] The invention is an improved cement anti-crack modifier, which is made of the following raw materials in parts by weight:
[0014] 1.2 parts of lead salt stabilizer, 0.8 parts of camellia saponin, 3.5 parts of butane tetracarboxylic acid, 4 parts of kaolin, 1.5 parts of silicon oxide, 1.2 parts of glycerol triglyceride, 1.5 parts of polyvinyl acetate and 2.5 parts of molybdenum red share.
Embodiment 3
[0016] The invention is an improved cement anti-crack modifier, which is made of the following raw materials in parts by weight:
[0017] 3.2 parts of lead salt stabilizer, 3.6 parts of camellia saponin, 7 parts of butane tetracarboxylic acid, 8 parts of kaolin, 2.7 parts of silicon oxide, 2.8 parts of glycerol triglyceride, 3.5 parts of polyvinyl acetate and 4.2 parts of molybdenum red share.
[0018] Compared with the existing cement modifiers, the modifier of the present invention has low cost and better solves the technical problems of cement hardening, poor water resistance, small cohesive force, non-abrasion resistance, and non-freezing resistance; A large number of tests have verified that after adding the modifier of the present invention to ordinary cement, the above-mentioned properties of ordinary cement are greatly improved.

Abstract
The invention discloses an improved cement crack resistance modifier. The improved cement crack resistance modifier is prepared from the following raw materials in parts by weight: 1.2-3.2 parts of lead salt stabilizer, 0.8-3.6 parts of oil-tea camellia saponin, 3.5-7 parts of butane tetracarboxylic acid, 4-8 parts of kaolin, 1.5-2.7 parts of silica, 1.2-2.8 parts of glyceryl trioleate, 1.5-3.5 parts of polyvinyl acetate and 2.5-4.2 parts of molybdate red. Compared with the existing cement modifiers, the modifier disclosed by the invention has the advantages that the cost is low, and the technical problems of cement hardening, poor waterproofing property, low bonding power, no wear resistance, no freezing resistance and the like are better solved; verified by a large number of tests, the properties of normal cement are greatly improved after the modifier disclosed by the invention is added into the normal cement.
Description
technical field [0001] The invention relates to an improved cement anti-crack modifier, which belongs to the field of building materials. Background technique [0002] The cement currently used in construction is prone to hardening, mainly due to the condensation of calcium hydroxide, calcium silicate and water. Such cement is prone to cracking, which in turn leads to low tensile strength and low toughness of cement. In order to solve this problem, it is generally necessary to add a modifier to this type of cement to improve the hardening phenomenon of the cement. However, some ordinary cements also have defects such as poor water resistance, low cohesive force, no wear resistance, and no frost resistance while being easy to harden. Currently there is no effective way to solve these problems. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an improved cement anti-c...
