Problems solved by technology

[0003] Although the current preparation formula and method of sealants have improved various conventional properties to a certain extent, they still cannot meet the increasingly stringent production requirements. Research on shortening the drying time of sealants and improving the strength, hardness and viscosity is very important for improving the current Productivity is intuitive

Abstract

The invention discloses a modified kaolin waterproof sealant and a preparation method thereof. The modified kaolin waterproof sealant is prepared from the following raw materials in parts by weight: 22 to 36 parts of hydrophobic modified kaolin, 11 to 16 parts of bisphenol A epoxy resin, 8 to 13 parts of palmitic acid, 9 to 14 parts of EPA, 11 to 15 parts of lignoceric acid, 7 to 13 parts of silicone oil, 10 to 15 parts of glass fiber, 4 to 7 parts of porcelain powder, 5 to 9 parts of asbestos powder, 3 to 7 parts of quartz powder, 4 to 17 parts of mica powder, 1.5 to 5 parts of plasticizers,1 to 4 parts of curing agents, 1.2 to 3 parts of anti-freeze agents, 2 to 4.5 parts of antioxidants, 1 to 3 parts of coupling agents and 1.5 to 3 parts of accelerants. The modified kaolin waterproof sealant is prepared through the steps of pulping, crosslinking reaction, precipitation, vacuum reaction, stirring, cooling, packaging, sealing and the like. The modified kaolin waterproof sealant has the advantages that the surface drying time and the gelation time are short; the strength and the hardness are high; the viscosity is high.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a modified kaolin waterproof sealant and a preparation method thereof. 【Background technique】 [0002] Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the configuration gap and play a sealing role. It has anti-leakage, waterproof, anti-vibration and sound insulation. heat insulation etc. Sealants are usually based on dry or non-drying viscous substances such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, and inert fillers such as talcum powder, clay, carbon black, titanium dioxide and asbestos. It is made by adding plasticizer, solvent, curing agent, accelerator, etc. It is generally divided into three categories: elastic sealant, liquid gasket and seal putty, and is widely used in construction, tra...
