Abstract

The invention discloses a waterproof and high temperature resistant sealant and a preparation method thereof. The waterproof and high temperature resistant sealant includes the following raw materials by weight: 50-80 parts of an acrylate emulsion, 5-10 parts of nitrile rubber, 10-20 parts of potato waste residue powder, 12-18 parts of talcum powder, 10-13 parts of expandable graphite, 1-3 parts of glass bead, 5-6 parts of gas phase white carbon black, 5-8 parts of nano calcium carbonate, 10-12 parts of epoxidized soybean oil, 0.5-1.5 parts of dibutyl tin diacetate, 3-5 parts of dibutyl phthalate, 5-10 parts of zinc borate, and 2-3 parts of pentaerythritol. The preparation method consists of: (1) subjecting potato waste residue to natural air dying and crushing, conducting soaking in dimethyl methylphosphate for 5-10h, carrying out separation and natural drying to obtain potato waste residue powder; and (2) mixing the raw materials according to the ratio in certain sequence to prepared the sealant. According to the invention, the potato starch waste, expandable graphite and talcum powder are mixed to obtain the biomass charring agent with flame retardant effect. And by applying the biomass charring agent into the sealant, the high temperature resistance, flame retardation and waterproofness of the sealant can be significantly improved, and at the same time the waste treatment cost of starch production enterprises can be reduced, thereby being beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of high-temperature resistant materials, in particular to a water-resistant and high-temperature resistant sealant and a preparation method thereof. Background technique [0002] It is used as a sealant for fireproof isolation of various openings formed when cables, air ducts, oil pipes, air pipes, etc. pass through walls and floors and for cable trays. Due to the requirements of special environments, the sealants used must be resistant to radiation, water, and Aging, high temperature resistance, flame retardant and other high performance. Existing sealants cannot have special properties such as water resistance, high temperature resistance, and radiation resistance at the same time. [0003] Potato waste residue is the residual waste produced in the processing and production of starch factories. It is mainly composed of starch, cellulose and hemicellulose, which is not only difficult to handle but also cau...
