Abstract

The invention belongs to the technical field of manufacturing of a heat-insulating material, and provides a composite heat-insulating material and a preparation method thereof. The heat-insulating material comprises the following components: 80 to 90 parts of modified glass cotton, 10 to 20 parts of polyphenyl granules, 4 to 10 parts of white carbon black, 0.5 to 1.1 parts of a penetrating agent, 0.3 to 1.5 parts of aluminum silicate wool, 0.6 to 1.9 parts of an adhesive and 0.9 to 2.5 parts of an excitant; the modification method of the modified glass cotton comprises the steps of soaking with a modifier for 30 to 60 minutes and curing; the modifier comprises the following raw materials: 30 to 70 parts of a sodium silicate solution, 4 to 20 parts of barium hydroxide, 4 to 10 parts of melamine, 2 to 5 parts of propyl alcohol, 2 to 4 parts of antimonous oxide, 2 to 5 parts of chlorinated paraffin and 1 to 3 parts of a curing agent. The preparation method of the composite heat-insulating material is simple in process; the cement loving property of the prepared heat-insulating material is improved, the volume weight is small, the heat-conducting coefficient is small, and the fire-resistant capability is high.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material manufacturing, and in particular relates to a composite thermal insulation material and a preparation method thereof. Background technique [0002] Insulation materials can be divided into three categories: metal insulation materials, organic insulation materials, and inorganic insulation materials. [0003] Metal insulation materials, but the supply of this material is very small and the price is very expensive. As a building insulation material, it will greatly increase the cost and cannot be widely used. [0004] Organic thermal insulation materials are easy to burn, easy to produce toxic gas at high temperature, and have poor aging resistance and fire resistance. These shortcomings limit the wide use of organic thermal insulation materials. [0005] At present, cement, aerated concrete, benzene board, glass wool board, phenolic foam insulation board, etc. are widely used i...
