Light mass and thermal-insulation heat-preservation material and preparation method thereof

Abstract

The invention discloses a light mass and thermal-insulation heat-preservation material and a preparation method thereof. The preparation method comprises the following steps: putting 40-50 parts of waste glass, 20-30 parts of waste fibers, and 15-25 parts of sorbitol into a ball mill, performing powder grinding, and performing mixing to obtain a mixed powder material; putting the mixed powder material into a mould, adding 10-15 parts of hydrogen peroxide and 3-6 parts of high-iron bauxite, and performing a reaction under stirring for 5-10min under a temperature of 100-120 DEG C; adding 3-5 parts of ammonium carbonate, 2-4 parts of potassium hexatitanate whiskers and 3-6 parts of silicon carbide, raising a temperate to 400-500 DEG C at a temperature raising speed of 3-5 DEG C / min, and keeping the temperature for 15-25min; raising a temperature to 1050-1150 DEG C at a temperature raising speed of 10-15 DEG C / min, and keeping the temperature for 1-3h; and performing cooling, performing demoulding, and performing cutting to obtain the light mass and thermal-insulation heat-preservation material. According to the invention, strength and flame retardant performance of the light mass and thermal-insulation heat-preservation material are improved, meanwhile waste is turned into wealth, and resources are saved.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, in particular to a lightweight thermal insulation material and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, glass is not only widely used in housing construction and people's daily life, but also developed into an indispensable new material for scientific research, production and cutting-edge technology. At the same time, it is inevitable to produce a lot of glass waste and form a large amount of waste glass. Take the glass factory as an example, under normal production conditions, the corner glass cut from the original plate glass accounts for about 15%-25% of the total glass production, and a considerable part of the waste glass is the waste glass produced by regular shutdown. It accounts for about 5%-10% of the total glass production. Occasional fluctuations in the...

Problems solved by technology

[0003] At present, in my country, traditional thermal insulation materials such as rock wool, glass wool, and expanded perlite still occupy the main market. Although these materials are relatively low in price, they have high density and poor thermal insulation performance (thermal conductivity is 0.065-0.090W / m· K), problems such as thick laying, large material loss, high moisture absorption, poor shock resistance and environmental protection performance, if these insulation materials are used, energy-saving standards cannot be met

In addition, building insulation materials such as asbestos and glass wool itself contain a large amount of harmful substances, which cannot meet the health requirements of human beings.

At present, the output of new foam plastic insulation materials (such as EPS, XPS, PUF, PET, etc.) in my country only accounts for 40% of the total insulation materials. Compared with traditional insulation materials, the thermal conductivity of foam plastics (such as Airex, etc.) Low coefficient, good thermal insulation effect, light weight, low water absorption, good chemical stability, convenient construction, but due to the relatively high price of foam plastics, it limits its large-scale use in China
