Problems solved by technology

For example, an inorganic thermal insulation and energy-saving material described in the application number CN201310671117.8 is simple to manufacture, has good heat and sound insulation effects, and has high strength, but the mechanical processing performance of the inorganic material is poor. Insulation effect
The thermal insulation performance of organic thermal insulation materials is relatively good, but the high temperature resistance is poor, the strength is low, and it is easy to age, especially the fire resistance performance is poor.
Most of the composite materials are organic composite boards, which have good thermal insulation effect and high light weight, but the cost is relatively expensive, and surface treatment is often required for construction at the same time

Abstract

The invention relates to the technical field of energy-saving materials, in particular to a novel thermal-insulating energy-saving material and a preparation method thereof. The thermal-insulating energy-saving material is prepared from the following components in parts by weight: 20-30 parts of coal ash, 20-30 parts of slag, 5-10 parts of expanded perlite, 5-10 parts of aluminium dihydrogen phosphate, 8-15 parts of glass wool, 3-8 parts of sepiolite, 3-8 parts of aluminium silicate cotton, 3-5 parts of aerosil, 6-12 parts of foaming agent, 10-15 parts of polystyrene, 3-5 parts of cellulose ether and 2-5 parts of water repellent. The obtained novel thermal-insulating energy-saving material has the characters of inorganic materials and organic materials at the same time, the thermal insulation and energy saving performance is excellent, the heat resistance and the strength are high, and meanwhile, the obtained novel thermal-insulating energy-saving material has good mechanical processing performance and low water absorption.

Description

technical field [0001] The invention relates to the technical field of energy-saving materials, in particular to a novel thermal insulation and energy-saving material and a preparation method thereof. Background technique [0002] With the rapid development of economy and technology, a series of problems have appeared along with it. Environmental problems and energy problems have become more and more serious. Among them, the shortage of energy has been paid more and more attention by people. The shortage of oil and coal resources has made people Have to start thinking about energy saving and consumption reduction. The construction industry has developed rapidly in recent years, and energy consumption is a huge waste. Many researchers have begun to consider research and development of new building materials to save energy and reduce unnecessary waste. Energy-saving and thermal insulation building materials have emerged as the times require. pregnancy. [0003] Insulation ma...
