Description

(1) Technical field

[0001] The invention relates to a thermal insulation board and a production method thereof, in particular to a phenolic foam thermal insulation board and a forming method thereof. (2) Background technology

[0002] According to statistics, an important reason for modern fires at construction sites is that the welding slag splashed by electric welders during construction causes the burning of insulation materials, and most of the fire casualties are caused by the dense smoke and poisonous gas produced by the fire. Among the EPS, XPS polystyrene foam, glass wool, mineral wool and polyurethane insulation boards currently on the market, only phenolic resin has the properties of flame retardant, low toxicity and low smoke. The thermal effect is also 2 to 3 times higher than that of ordinary roofing materials. After installing phenolic foam insulation boards on the outer walls and roofs, the heat insulation performance of the house is greatly enhanced, and the ...

Examples

Embodiment Construction

[0052] Examples see figure 1 As shown, the composite phenolic foam insulation board for construction has an upper coating 2 on the upper surface of the phenolic foam insulation board 1 and a lower coating 3 on the lower surface of the phenolic foam insulation board.

[0053] There are raw materials according to the following mass ratio in the composite phenolic foam insulation board:

[0054] [1] 100 parts of foamable phenolic resin.

[0055] [2] Any value between 10 and 25 parts of polyurethane.

[0056] [3] Any value between 0.5 and 5 parts of epoxy resin; the above-mentioned epoxy resin is any one of GEBR-440A80, ​​GEBR-450A80 or GEBR-500A80 special resin for copper foil laminates.

[0057][4] Any value between 10 and 20 parts of the flame retardant; the above-mentioned flame retardant is one or more of tetrabromobisphenol A, chlorinated paraffin, antimony trioxide and flame retardant HT-102 in a mixture.

[0058] [5] Any value between 0.5 and 2 parts of surfactant; the...
