Abstract

The invention relates to acrylic ester waterproof gasket cement and a preparation method thereof. The acrylic ester waterproof gasket cement includes a technology of environmental-friendly universal glass cement (the patent serial number is 200810083601.8) and comprises the following composition by weight: 30 parts of acrylic ester emulsion, 0.5-3 parts of dispersant, 2-10 parts of silica solution, 0.2-5 parts of coupling agent, 30-80 parts of filling, 0.1-2 parts of pH modifying agent and 0.5-2 parts of coalescing agent. The preparation method of the acrylic ester waterproof gasket cement comprises the following steps: adding one of a plasticizer, the coalescing agent and the coupling agent in a container to be mixed into liquid A, one of the silica solution, the coupling agent is added in another container to be mixed into liquid B, the acrylic ester emulsion is added in the containers, and the dispersant, the liquid A, the liquid B, the filing and the pH modifying agent are added in sequence during stirring the acrylic ester emulsion and the acrylic ester waterproof gasket cement is obtained after the mixture is evenly stirred. The invention overcomes the deficiencies that the aqueous gasket cement is not waterproof and has poor adhesiveness, the solvent-borne type gasket cement has good waterproof performance, but contains over 30 percent of VOC and pollutes the environment seriously, and most of organic solvent belongs to a petrochemical product and causes the waste of energy. The waterproof gasket cement is environmental-friendly and has good waterproof performance and adhesiveness.

Description

technical field [0001] The invention relates to a sealant and a preparation method thereof, in particular to a preparation method of an acrylate waterproof sealant. Background technique [0002] The waterproof sealant used in the market is basically a solvent-based butyl rubber sealant. Because the organic solvent of this product is as high as about 30%, it not only causes a waste of energy, but also seriously pollutes the environment. [0003] The existing acrylic acid building sealant products are water-based products, which are environmentally friendly and pollution-free, but have low technical content, simple production process, poor overall performance of the product, and basically no adhesion to smooth surfaces. Long-term water immersion (the People's Republic of China Building Materials Industry Standard JC / T484-2006) greatly limits its scope of use. Contents of the invention [0004] The purpose of the present invention is to provide a kind of production method of...
