Abstract

The invention discloses a concrete release agent with isolation and bonding functions and a preparation method of the concrete release agent. The concrete release agent with the isolating and bondingfunctions is prepared from engine oil, sodium hydroxide, an OP-10 emulsifier, a styrene-acrylate emulsion, a melamine water reducing agent, hydroxypropyl methyl cellulose, tributyl phosphate and waterthrough mixing and stirring. In this way, the invention discloses the concrete release agent with isolation and bonding functions and the preparation method thereof. According to the invention, the steel formwork and the concrete can be well isolated, the binding power of the fish plastering mortar can be increased, and secondary decoration is not affected after demolding; the method is suitablefor secondary processing of the surface of the concrete, the concrete adhesion amount is not larger than 0.2 g / m < 2 >, and the binding strength ratio is not smaller than 1.5.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete release agent with both isolation and bonding functions and a preparation method thereof. Background technique [0002] Concrete release agent refers to a substance applied on the construction formwork before concrete pouring, so that the formwork will not stick to the concrete surface after pouring, it will not be easy to remove the formwork, or affect the smoothness of the concrete surface. Its main function is to form a film on the formwork and concrete surface to isolate the two, so it is also called release agent. Concrete release agent is widely used in various steel formwork, wood formwork, bamboo plywood, plastic board and concrete countertops in concrete engineering construction. However, existing concrete release agents have problems such as good demoulding effect but poor secondary decoration, or good secondary decoration and poor demoulding effect. Cont...
