Abstract
To provide a type of phenol foam characterized by the fact that the phenol foam is formed by using a hydrocarbon as the foaming agent. The phenol foam has excellent heat-insulating performance, high compressive strength and other mechanical strengths, improved brittleness and is friendly to the environment of the earth.
Claims3
A type of phenol resin foam heat-insulating material, characterized by the following facts:
- the phenol foam has an independent porosity of at least 80%, an average pore size in the range of 10-400 mm, and a thermal conductivity of 0.025 kcal/mhr° C. or lower;
- the phenol foam is composed of a portion of pores filled with a gas containing C4-6 saturated hydrocarbon and a resin portion made of a phenol resin containing 0.01-5 wt % of at least one type of fluoroamine represented by the following formula (1):
- (CaFb)3N (1)
- In formula (1), a is a natural number of 4 or larger and b is 2a+1.
