The invention belongs to the technical field of chemical heat preservation materials, and is a fireproof and
flame-retardant phenolic heat preservation foam board, which consists of the following raw materials in parts by weight: 65-80 parts by weight of phenolic resin, 5-15 parts of
foaming agent, 5-10 parts of curing agent, and benzenesulfonate Acid 2.5-5,
benzoic acid 2.5-5, additives 1-5; during preparation, put phenolic resin,
foaming agent, and additives into a reaction kettle and keep warm at
room temperature, stir and mix evenly, and then add curing agent, benzenesulfon A closed-
cell rigid foam board made under the action of acid and
benzoic acid; the product of the present invention has the characteristics of light weight, non-
combustibility, low
smoke, high
temperature resistance, non-toxic, and no dripping. Due to the high closed-
cell rate of phenolic foam, the It has low
thermal conductivity, good heat insulation performance, and has
water resistance and
water vapor permeability. It is an ideal
thermal insulation and energy-saving material. The foam insulation material is light in weight and convenient in construction.
