Concrete demolding agent

Abstract

The invention discloses a concrete demolding agent prepared from the following raw materials in parts by weight: 9-15 parts of polyvinyl alcohol, 3-9 parts of solid paraffin, 7-11 parts of nonylphenol polyoxyethylene ether, 2-6 parts of molasses, 5-9 parts of rosin pyrolytic polymer, 7-10 parts of sepiolite fabric, 3-8 parts of polyisobutylene succinimide, 3-5 parts of polyanionic cellulose, 6-9 parts of graphene oxide, 3-8 parts of polyester rubber powder, 1-5 parts of rosin, 9-16 parts of tributyl phosphate, 0.2-1 part of ammonia water and 2-6 parts of stearic acid. The concrete demolding agent disclosed by the invention has the beneficial effects of being nontoxic and tasteless, having a good demolding effect, and being very good in waterproof and antirust effects and low in cost.

Description

technical field [0001] The invention relates to a concrete release agent. Background technique [0002] Aiming at the problems of concrete products and construction industry formwork storage in the market that are easy to rust, air bubbles on the concrete surface, easy to pollute the concrete surface, and difficult to remove and clean the mold, people have developed a release agent. Traditional concrete release agents such as waste engine oil and waste diesel oil , Emulsified engine oils, modified resins and saponified oil feet. Waste engine oil and waste diesel oil contain impurities and a lot of water, and the concrete surface after demoulding is polluted by waste oil, which is not environmentally friendly and not beautiful. At the same time, it is difficult to remove on the template, and the template is not well maintained. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to ...

Problems solved by technology

[0002] Aiming at the problems of concrete products and construction industry template storage in the market, which are easy to rust, have air bubbles on the concrete surface, easy pollution on the concrete surface, and difficulty in demoulding and cleaning, people have developed a release agent. The traditional concrete release agent is waste engine oil and waste diesel oil. , emulsified engine oils, modified resins and saponified oil feet

Waste engine oil and waste diesel oil contain impurities and a lot of water, and the concrete surface after demoulding is polluted by waste oil, which is not environmentally friendly and not beautiful

At the same time, it is difficult to remove on the formwork, and it is not effective in the maintenance of the formwork
