High-molecular cement-surface moisture-proof agent formula

Abstract

The invention discloses a high-molecular cement-surface moisture-proof agent formula. All constituents comprise epoxy resin, a mixture of phenol-aldehyde amine and polyamide and solvent. The volume ratio of the epoxy resin to the mixture of the phenol-aldehyde amine and the polyamide is 7:3, and the volume of the solvent is the sum of the volume of the epoxy resin and the volume of the mixture of the phenol-aldehyde amine and the polyamide. The surface of the cement surface is coated with the moisture-proof agent prepared through the epoxy-resin high-molecular material and the like, the bonding effect can be achieved, and meanwhile a compact protective layer formed by the moisture-proof agent can have the moisture-proof effect, double purposes are achieved, and a series of problems caused by a traditional plastic track are thoroughly solved.

Description

technical field [0001] The invention belongs to the field of chemistry and chemical engineering, and in particular relates to a formula of a cement surface anti-moisture agent used in plastic runways. Background technique [0002] Plastic tracks are often seen in running competitions and exercises. The current plastic track is either placed on the asphalt surface or the cement surface, and the asphalt surface is very high in terms of construction difficulty and construction cost, so The current plastic runway plastic is still mostly placed on the cement surface. After the plastic layer is laid on the cement surface and used for a long time, the moisture and heat in the cement surface will easily evaporate and penetrate into the plastic layer. This will easily cause the plastic layer to peel, bulge, or even directly The damage can not be used, not only affects the normal use of the runway, but also increases the cost of use, if there is a material coated between the two, it c...
