Abstract

The invention relates to a preparation method of a high efficient and energy saving phenolic foam board, which includes the steps of: (1) preparing raw materials according to the following components and weight parts: 100 parts of expandable resol resin, 2-6 parts of a foaming agent, 5-15 parts of a fire retardant, 2-4 parts of a foam stabilizer, and 10-20 parts of a curing agent; (2) mixing above raw materials and stirring infirmly the raw materials at the high speed, pouring the raw materials into a die, sealing the die, and putting the die into a baking oven; and (3) controlling the temperature of the baking oven, carrying out staging foaming treatment on the die at different temperatures, taking out the die after the staging foaming treatment ends, namely preparing the high efficient and energy saving phenolic foam board. Compared with the prior art, the prepared product accords with high efficient, energy saving, and light characteristics. The thermal conduction coefficient may be low to 0.022W / m*K.

Description

technical field [0001] The invention relates to the field of thermal insulation materials for external walls, in particular to a method for preparing a high-efficiency and energy-saving phenolic foam board. Background technique [0002] With the continuous occurrence of fires of external wall insulation materials, more and more researches have been done on the use of external wall insulation materials in construction projects. Among many thermal insulation materials, phenolic foam foamed from phenolic resin is known as the "king of thermal insulation" as a new type of thermal insulation material. At the same time, it has the advantages of fire resistance, corrosion resistance, and environmental protection, and has been widely used abroad. Many countries specify that architectural design prefers phenolic foam as a building thermal insulation material. Because domestic research on phenolic foam started relatively late, many properties are far below foreign levels, so the use ...
