High polymer molecule modified waterproof and anticorrosive resin mortar and preparation method thereof

Abstract

The invention provides high polymer molecule modified waterproof and anticorrosive resin mortar and a preparation method thereof, and relates to the field of resin mortar materials. The composition comprises the following components in parts by weight: 60-80 parts of POSS modified epoxy resin; 5-10 parts of liquid chloroprene rubber, 5-10 parts of liquid polysulfide rubber, 5-10 parts of carboxyl-terminated polybutadiene, 10-15 parts of talcum powder, 10-15 parts of modified clay, 1-5 parts of N550 carbon black, 4-8 parts of expanded and vitrified micro bubbles, 4-8 parts of expanded polyphenyl particles, 5-10 parts of polycrystalline aluminum oxide fibers, 1-3 parts of 2, 4, 6-tri (dimethylaminomethyl) phenol, 1-3 parts of polypropylene glycol diglycidyl ether, 0.1-1 part of aminosilane,0.1-1 part of vinyltriethoxysilane, 3-6 parts of polyethylene wax, 1-3 parts of hydroxyethyl cellulose, 1-3 parts of a thixotropic agent, 5-10 parts of a binding agent, 5-10 parts of a diluent and 1-2parts of a curing agent. The high polymer molecule modified waterproof and anticorrosive resin mortar has excellent mechanical properties and excellent crack resistance, impermeability, compression resistance, alkali resistance, acid resistance and salt corrosion resistance, and all the properties meet the use requirements.

Description

technical field [0001] The invention relates to the field of resin mastic materials, in particular to a polymer molecularly modified waterproof and anti-corrosion resin mastic and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, a large number of buildings have sprung up, but there are often cracks in the walls of the buildings. There are many reasons for this situation, such as uneven settlement of the foundation, and uneven wall materials caused by temperature changes. Rules bloated. Traditional caulking adhesives are generally added with organic solvents, which pose a potential threat to the human body and the environment, and their waterproof and anti-corrosion performance is poor, and they are easy to peel off after a period of time, or because the process is too cumbersome, it brings many problems to production and construction. the inconvenience. [0003] Resin cement is a kind of polymer molecular modifi...

AI Technical Summary

Problems solved by technology

Epoxy resin will form a highly cross-linked three-dimensional network structure during curing, and the molecular chains are not easy to slide, so that after curing, the internal stress is large, brittle, and cracks are easy to occur, and the impact resistance and crack resistance are poor. Lead to poor waterproof and anti-corrosion performance of epoxy cement made of it
