Abstract

The present invention belongs to the field of building material technology, in the concrete, it relates to a waste rubber powder flexible acrylic acid water-base joint-filling material and its preparation method. It is made up by using rubber powder obtained by processing waste tyre as aggregate, and mixing it with the chemical raw materials of acrylic acid elastic emulsion, sodium hexametaphosphate, sodium benzoate, ethylene glycol, propylene glycol, polydimethylsiloxane, methyl cellulose, calcium carbonate and colouring agent according to a certain mixing ratio.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a flexible acrylic water-based joint filling material of waste rubber powder and a preparation method thereof. Background technique [0002] With the development of economy, the development of urban construction has been brought about. At present, in the field of urban construction, on the one hand, with the rapid development of municipal construction, various new energy-saving and environmentally friendly building materials are called for. Because the promotion and application of many new energy-saving building materials requires the combination of many supporting materials to become an application system that is easy to use and has perfect performance. Some new wall building materials often encounter splicing joints, shrinkage joints, external wall insulation and heat insulation after using energy-saving materials, etc., which require the application of n...
