Abstract

The present invention relates to the technical field of construction chemicals, and in particular relates to efficient building waterproof powder. The building waterproof powder comprises the following materials by weight: 10-30% of fly ash, 10-20% of quick lime, 10-20% of superfine mineral powder, 8-15% of coconut oil, 5-10% of calcium hydroxide, 5-10% of zinc stearate, 1-2% of a polycarboxylate superplasticizer, 1-2% of sodium sulfate, 0.5-2% of a surfactant and 1-3% of an anticorrosion sustained-release agent. Object of the present invention is to provide low-cost environmentally-friendly practical efficient building waterproof powder.

Description

technical field [0001] The invention relates to the technical field of building chemical industry, in particular to a high-efficiency building waterproof powder. Background technique [0002] At present, there are phenomena such as leakage and seepage in both old and new buildings in China. Capillary pores, settlement gaps, and shrinkage cracks in concrete members are the main water seepage channels. Water repellent has the functions of water repellency, waterproof, increasing the fluidity of concrete for easy pumping, micro-expansion, and plastic retention. Therefore, water repellent is the main material to improve and prevent water seepage of concrete. Currently, concrete waterproofing agents are generally in the form of water and powder. Water-based water-based water-based waterproofing properties are poor in acid and alkali resistance, have a pungent smell, and are prone to cracks when poorly maintained. Powder form, high cost, difficult to popularize and use. Conten...
