Abstract

The invention discloses fire-retardant and thermal-insulation mortar. The mortar consists of the following raw materials in parts by weight: 30-40 parts of high-alumina cement, 40-50 parts of glass bead, 10-15 parts of carborundum, 0.5-1 part of hydroxypropyl methyl cellulose, 2-4 parts of viny acetateethylene emulsion (VAE) re-dispersible emulsion powder, 1-3 parts of polypropylene fiber, 0.5-1.5 parts of wood fiber, 5-10 parts of heavy calcium powder, 3-6 parts of seaweed powder, 4-8 parts of brucite powder, 3-5 parts of mica powder, 8-12 parts of kaolin, 5-10 parts of gypsum, 0.3-0.5 part of polycarboxylic water reducer and 4-6 parts of thermal insulation particles. The fire-retardant and thermal-insulation mortar disclosed by the invention is excellent in fire retardant performance, good in flame retardant property, good in thermal insulation and heat preservation performance, high in binding strength, strong in adhesive force, excellent in crack resistance and weather fastness, low in cost and wide in application prospect and is convenient to construct, and fire retarding grade reaches A grade.

Description

technical field [0001] The invention relates to a fire-resistant and heat-preserving mortar, which belongs to the field of building materials. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is mainly used to construct building surface insulation As a kind of building material, it has the characteristics of energy saving and waste utilization, thermal insulation, aging resistance, low price and convenient construction, etc., and has a wide market demand. At present, there are many kinds of thermal insulation mortars on the market, and their properties are uneven. Most thermal insulation mortars still have the disadvantage of poor fire resistance, which seriously affects the fire performance of buildings. Contents of the invention [0003] The object of the present invention is to provide a...
