Abstract
The invention provides a concrete demoulding agent. The concrete demoulding agent is prepared from the following raw materials in parts by weight: 10-15 parts of vinyl alcohol, 4-7 parts of polyisobutylene succinimide, 3-6 parts of sepiolite texture, 8-12 parts of oleic acid, 12-15 parts of emulsified oil, 4-8 parts of talcum powder, 6-8 parts of sodium borate, 5-8 parts of epoxy resin, 1-3 parts of nonyl phenol polyoxyethylene ether, 5-7 parts of sodium alginate, 0.1-0.3 part of chitin and 2-4 parts of an anti-freezing agent. The demoulding agent disclosed by the invention is good in demoulding effect, the decoration effect of a concrete surface is not influenced after demoulding, frost crack cannot occur in winter, and the concrete demoulding agent can be recycled repeatedly, so that the using efficiency is greatly improved, and the cost is also reduced.
Description
technical field [0001] The invention relates to a release agent, in particular to a concrete release agent. Background technique [0002] Concrete is one of the most important civil engineering materials at present. It is prepared in a certain proportion from cementitious materials, granular aggregates, water, and admixtures and admixtures if necessary. In order to ensure that the appearance and shape of concrete are intact and To prevent the formwork from being damaged by knocking, a release agent is usually added to the concrete. Most of the release agents in the prior art are disposable products, which cannot ensure the decorative effect on the concrete surface, and are difficult to meet the quality requirements such as not polluting steel bars and concrete, and the release effect is not very satisfactory. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a concrete release agent which is convenient for demould...
