Abstract

The invention discloses a flame-retardant cement-based cushion self-leveling, which is composed of the following raw materials in percentage by weight: 18-25% of cement, 10-20% of aggregate, 5-10% of fines, 0.15-0.2% of super-plasticizer, 15-25% of styrene-acrylic emulsion, 0.1-0.2% of water reducer, 0.1-0.25% of flame retardant, and the balance being water. The flame-retardant cement-based cushion self-leveling can solve the waterproof problems in the upstream face or downstream face of a building project, has the characteristics of firm adhesiveness, good flame retardant effect, simple production, convenience, and little investment, and has a good waterproof and flame retardant performance with a construction thickness of 3 to 4 mm.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a self-leveling cement-based cushion with a flame-retardant type. Background technique [0002] Self-leveling mortar includes cement-based self-leveling / self-leveling mortar / leveling mortar, etc., which are products with high technological content and complex technical links. It is a dry-mixed powdery material composed of multiple active ingredients, which can be used by mixing water on site. After a slight spread of the scraper, you can get a high level base surface. The hardening speed is fast, you can walk on it within 24 hours, or perform follow-up projects (such as laying wooden floors, diamond boards, etc.). The fast and simple construction is unmatched by traditional manual leveling. Self-leveling mortar is safe to use, pollution-free, beautiful, fast construction and put into use are the characteristics of self-leveling cement. It enhances the civilized construct...
