Flexible composite silicate thermal insulation board material and preparation method

Abstract

The invention discloses a flexible composite silicate insulation board material and a preparation method thereof, belonging to the technical field of insulation materials. The flexible composite silicate insulation board material of the present invention is mainly made of volcanic rock fiber and sepiolite, and is compounded by adding silicon dioxide, binder, flexible agent and surfactant. The composite silicate insulation board material prepared by the invention does not contain asbestos and does not pollute the environment; it is bendable and convenient for construction; it has light weight, good flexibility, high rebound rate, good thermal stability, low thermal conductivity, and good thermal insulation performance Etc. It is suitable for heat preservation of equipment, containers, pipelines and other products in chemical, petroleum, thermal power and other enterprises and institutions. The method of the invention has the advantages of low cost, simple operation, easy large-scale industrialization and the like.

Description

technical field [0001] The invention relates to a flexible composite silicate insulation board material and a preparation method thereof, belonging to the technical field of insulation materials. Background technique [0002] my country's economy has grown rapidly, and various constructions have made great achievements, but it has also paid a huge amount of energy consumption. In energy consumption, heat loss accounts for a considerable proportion. Therefore, thermal insulation materials have developed rapidly in recent years, and their demand in chemical, petroleum, electric power, metallurgy, transportation, national defense, construction and other industries is increasing. Thermal insulation materials can be generally divided into organic thermal insulation materials and inorganic thermal insulation materials according to their composition. Although organic thermal insulation materials such as polystyrene and polyurethane have low thermal conductivity, they are easy to bu...

Problems solved by technology

However, these traditional silicate thermal insulation materials are prone to convective heat dissipation due to the unsealed internal space of the molding material, resulting in unsatisfactory thermal insulation effects, and also have defects such as short service life, easy cracking, and great harm to the human body.
