A new type of inorganic heat insulation flame retardant material and its preparation method

Abstract

The invention belongs to the field of heat insulation and flame retardant materials, and discloses a novel inorganic heat insulation and flame retardant material and a preparation method thereof. In parts by weight, it is made of the following raw materials: 2-20 parts of unsaturated resin, 0.02-0.05 parts of initiator, 0.5-5 parts of coupling agent, 20-50 parts of fiber material, and 100 parts of hollow glass microspheres. The new inorganic thermal insulation and flame retardant material prepared by the present invention also ensures good mechanical properties on the basis of thermal insulation and flame retardant properties; compared with traditional organic thermal insulation and flame retardant materials, it has more obvious advantages, that is, more Low density and good compressive properties; compared with airgel and other inorganic thermal insulation materials, it effectively reduces the problem of particles falling off easily on the basis of ensuring excellent thermal insulation properties.

Description

technical field [0001] The invention belongs to the field of heat-insulating and flame-retardant materials, and in particular relates to a novel inorganic heat-insulating and flame-retardant material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of construction, petrochemical, shipbuilding and other industries, materials with light weight, fire resistance and low toxicity have gradually attracted attention. At present, in the construction industry, thermal insulation materials have been used in central air-conditioning systems in a large number of national and local key projects, saving a lot of energy and making up for the shortcomings of traditional thermal insulation materials in terms of durability, environmental protection and fire prevention; The basic economic industry requires a large number of various pipelines to support a series of processes. In order to meet production requirements, save energy, and im...

Problems solved by technology

[0003] At present, the heat insulation and flame retardant materials that dominate the market are mainly organic foam flame retardant materials, such as polystyrene foam, polyvinyl chloride foam, polyurethane foam, etc., which have low heat resistance temperature and release a large amount of heat after burning. A large amount of smoke and poisonous gas not only causes environmental pollution, but also becomes one of the main factors causing casualties in fires

Phenolic foam is a new type of foam developed in recent years. It has attracted extensive attention in the industry for its heat insulation, sound insulation, and high-temperature stability.

Among inorganic thermal insulation materials, airgel is currently the material that has received widespread attention. Although it can meet the requirements of the industry, its high cost and powder drop during use limit its large-scale application.
