Problems solved by technology

The traditional demoulding material is to add diesel oil or waste engine oil, which is easy to pollute the concrete surface and cause different degrees of pollution to the environment
At present, the domestic release agents mainly include soap release agents, oil release agents, paraffin release agents and oil-based release agents, which generally have poor release effects, are difficult to remove after removal, and are easy to damage the concrete surface. Defects that cause damage, affect construction efficiency and increase construction costs

Abstract

The invention discloses nanometer titania reinforced concrete mold release agents, and relates to the technical field of concrete mold releasing. The nanometer titania reinforced concrete mold release agents comprise, by weight, 5-8 parts of nanometer titania, 80-90 parts of glycerol ester of rosin, 50-60 parts of polyether modified silicone, 15-20 parts of zeolite powder, 15-20 parts of volcanic soil, 12-18 parts of octadecanamide, 10-15 parts of polyamide resin, 10-15 parts of saponin powder, 10-15 parts of emulsified oil, 8-12 parts of spans, 6-10 parts of lubricating grease, 6-10 parts of rice bran wax, 4-7 parts of tartaric acid, 30-40 parts of mandarin oil and 300-350 parts of water. The nanometer titania reinforced concrete mold release agents have good mold release performance, enable a mold plate and concrete to be smoothly released, keep the surface of concrete smooth and keep edges tidy and undamaged.

Description

Technical field: [0001] The invention relates to the technical field of concrete mold release, in particular to a nano-titanium dioxide reinforced concrete mold release agent. Background technique: [0002] Concrete release agent, also known as concrete release agent or release lubricant, is a substance that is applied to the inner wall of the formwork to lubricate and isolate, so that the concrete can be smoothly separated from the formwork when the formwork is removed, and the shape of the concrete is kept intact. The traditional demoulding material is to add diesel oil or waste engine oil, which is easy to pollute the concrete surface and cause different degrees of pollution to the environment. At present, the domestic release agents mainly include soap release agents, oil release agents, paraffin release agents and oil-based release agents, which generally have poor release effects, are difficult to remove after removal, and are easy to damage the concrete surface. The ...
