Embodiment Construction

[0010] A refractory and thermal insulation mortar, which is composed of the following raw materials by weight (kg): high alumina cement 36, vitrified microbeads 42, corundum 10, hydroxypropyl methylcellulose ether 0.6, VAE redispersible latex powder 3, poly Propylene fiber 2, wood fiber 0.8, heavy calcium powder 7, seaweed powder 4, brucite powder 6, mica powder 4, kaolin 10, gypsum 8, polycarboxylate water reducer 0.4, heat preservation particles 5;

[0011] The preparation method of the heat preservation particles is as follows: a. Weigh dolomite, coke gemstone, sillimanite, and volcanic rock in a weight ratio of 6:4:2:1, mix them evenly, pulverize them, wet ball mill for 24 hours, dry them, and place them in 880 Calcined at ℃ for 2 hours, cooled to room temperature, then added to a hydrochloric acid solution with a concentration of 15%, heated to 90℃ in a water bath, kept for 20min, washed with distilled water until neutral, dried, and then calcined at 1220℃ for 0.5 h, wate...

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...
