Embodiment Construction

[0016] The foam concrete insulation board used for the roof of the present embodiment is prepared from the following raw materials in parts by weight: 500 parts of electric furnace phosphorus slag, 100 parts of fly ash, 60 parts of kaolin, 40 parts of gypsum, 30 parts of polyvinyl alcohol, fat 4 parts of alcohol polyoxyethylene ether sodium sulfate, 12 parts of glacial acetic acid, 15 parts of hydrogen peroxide, 15 parts of vinyl acetate, 10 parts of diacetone acrylamide, 30 parts of cement, 8 parts of zinc stearate, 30 parts of trisilane, ammonium bicarbonate 40 parts, appropriate amount of water.

[0017] The foamed concrete insulation board used for the roof of the present embodiment is prepared by the following steps:

[0018] (1) Dry the phosphorus slag, fly ash, kaolin and gypsum in a 60°C drying oven for 30 hours, ball mill for 40 minutes, pass through a 200-mesh sieve, mix well and set aside;

[0019] (2) Add water equivalent to 6 times the weight of polyvinyl alcohol...

Abstract

A foam concrete insulation board for roofs is characterized by being prepared from raw materials in parts by weight as follows: 500 parts of electric furnace phosphorus slag, 80-100 parts of fly ash, 50-60 parts of kaolin, 30-40 parts of gypsum, 20-30 parts of polyvinyl alcohol, 3-4 parts of sodium fatty alcohol polyoxyethylen ether sulphate, 10-12 parts of glacial acetic acid, 12-15 parts of hydrogen peroxide, 12-15 parts of vinyl acetate, 8-10 parts of diacetone acrylamide, 20-30 parts of cement, 6-8 parts of zinc stearate, 20-30 parts of trisilane, 30-40 parts of ammonium bicarbonate and an appropriate amount of water. The foam concrete insulation board for roofs has the characteristics of being light in weight, low in cost, high in strength and prominent in heat preservation, thermal insulation and sound insulation effect and facilitates construction and installation.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a foam concrete insulation board for roofing and a preparation method thereof. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Foamed concrete is to introduce air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it forms a concrete with a large number of small closed pores and has considerable strength. products. [0003] Because foam concrete contains a large number of closed small pores, it has good thermal performance, that is, good thermal insulation performance, which is not available in ordinary concrete. Generally, t...
