Abstract

The invention discloses an anti-freezing type polycarboxylic acid high-performance water reducer and a preparation method thereof. The anti-freezing type polycarboxylic acid high-performance water reducer is prepared from the following materials in parts by weight: 25-35 parts of acrylic acid, 10-20 parts of mercaptoacetic acid, 30-50 parts of isopentenol polyoxyethylene ether, 1-10 parts of hydrogen peroxide, 1-10 parts of vitamin C, 1-5 parts of white sugar, 0.5-2 parts of sodium dodecyl sulfate, 1-10 parts of sodium nitrite, 1-5 parts of calcium chloride, 1-3 parts of air entraining agent and 25-60 parts of water. The invention further provides a preparation method of the water reducer. The production process in the invention is simple to operate, free of heating and pure water, low in energy consumption, green and environment-friendly, realizes zero pollution and zero emission in the production process, is a green synthesis method, and satisfies novel environment health requirements.

Description

technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a polycarboxylate high-performance water reducer with antifreeze and antirust properties. Background technique [0002] At present, there are many kinds of polycarboxylate superplasticizers on the market.
