Abstract

The invention discloses a heat preservation and insulation felt material which is composed of heat preservation sheets and reflection material which are pasted together alternately. Each heat preservation sheet mainly comprises asbestos-free manmade inorganic fiber, inorganic heat preservation particles, a reflection sheet, a dispersing agent, an adhesive agent and the like. The heat preservationand insulation felt material has the advantages of low heat conduction coefficient, good heat preservation property, high use temperature and wide application range; more important, the heat preservation and insulation felt material does not contain asbestos fiber while keeping the advantages of soft texture, no burning, low heat conduction coefficient, easiness of construction and the like. The heat preservation and insulation felt material meets the requirements of professional health protection and environment protection, and can be widely used for device and pipeline heat preservation.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a novel thermal insulation felt and a preparation method thereof. Background technique [0002] At present, thermal insulation materials produced industrially are mainly divided into two categories: inorganic thermal insulation materials and organic thermal insulation materials. [0003] Organic insulation materials are mainly various polymer foam materials, such as rubber and plastic foam, polyethylene foam, polystyrene foam, etc. The advantages of this type of insulation material are mature technology, large-scale production, low thermal conductivity, and good insulation effect , However, its fatal flaws are its low use temperature (most use temperatures are lower than 100°C), easy to burn, and low fire rating. [0004] Inorganic insulation materials can be divided into hard insulation materials and soft insulation materials. Hard thermal insu...
