Embodiment 1

[0021] A composite thermal insulation board is composed of silica aerogel, polyurethane, cement, high-efficiency flame retardant, flame retardant, antioxidant D, and expanded perlite through mixed processing. The above-mentioned expanded perlite has a bulk density of 100~150㎏ / m3, and the particles with a particle size of less than 5 mm should be above 90%. The manufacturing method is to take 1kg of silica aerogel, 30kg of polyurethane, 5kg of cement, 2.4kg of high-efficiency flame retardant, 0.8kg of flame inhibitor, D0.2kg of antioxidant, and 30kg of expanded perlite according to the weight ratio. Put them into a mixing tank and mix them for 5 minutes; after they are evenly mixed, they will be transported to the prefabricated mold for foaming and forming. Then, the shaped plates will be sent to the drying kiln. After being dried for 24 hours, they will be pushed out as the finished product.

Embodiment 2

[0023] The second embodiment is basically the same as the first embodiment. The difference is that 0.5 kg of silica aerogel, 25 kg of polyurethane, 4 kg of cement, 2 kg of high-efficiency flame retardant, and 0.5 kg of flame inhibitor are taken according to the weight ratio. , 0.1kg of antioxidant D and 25kg of expanded perlite are respectively put into a mixing tank and stirred evenly, after pre-foaming, then drying to prepare.

Embodiment 3

[0025] Example 3 is basically the same as Example 1. The difference is that 1.5kg of silica aerogel, 35kg of polyurethane, 6kg of cement, 3kg of high-efficiency flame retardant, 1kg of flame inhibitor, 0.3kg of antioxidant D and 35kg of expanded perlite are respectively put into a mixing tank and stirred evenly, after pre-foaming, and drying to prepare.

Abstract

A compound heat preservation plate is characterized in that the compound heat preservation plate is composed of silica aerogel, polycarbamate, cement, efficient flame retardant, flame retardant, antiager D and expanded perlite in an evenly mixing and stirring mode. The compound heat preservation plate comprises, by weight, 0.5-1.5 kilograms of silica aerogel, 25-35 kilograms of polycarbamate, 4-6 kilograms of cement, 2-3 kilograms of efficient flame retardant, 0.5-1 kilogram of flame retardant, 0.1-0.3 kilogram of antiager D and 25-35 kilograms of expanded perlite which are respectively placed into a stirring pot to be evenly stirred. After prefabricated foaming, the compound heat preservation plate is prepared through drying. The compound heat preservation plate is small in hygroscopicity, low in heat conductive coefficient, extensive in temperature range, light in material quality, firm, durable and convenient to use, and completely conforms nationally advocated requirements such as fireproofing, heat preservation, environmental protection and energy saving.

Description

Technical field [0001] The invention relates to a building board, in particular to a composite heat-preserving board that not only has energy-saving and heat-preservation effects, but also has fire-proof performance. Background technique [0002] Building energy conservation is a major national policy, and the task of energy conservation and emission reduction is very arduous. The new indicators of building energy conservation have been included in the national "Twelfth Five-Year Plan". It is a hard task that must be completed and is also a need for the development of a low-carbon economy. With the continuous deepening of the country's wall material reform, the application ratio of new wall materials and energy-saving insulation materials has increased year by year, but new requirements have been put forward for the performance requirements and construction methods of insulation materials. At present, the commonly used thermal insulation materials are organic thermal insulation m...
