Abstract

The invention relates to a toughened enhanced phenolic foam insulation material. The material is characterized by mainly comprising the following raw materials: 100 parts of phenolic resin, 2-10 parts of phenolic resin fluidity improver, 5-15 parts of emulsifying agent, 4-8 parts of foaming agent, 1-10 parts of toughening-enhancing agent, and 6-55 parts of reactivity acid curing agent. The reactivity acid curing agent in high additive amount is adopted so that the cost is lowered, and the system residual acid is small and the corrosivity is small. The glass fiber powder and diatomite are used as the toughening-enhancing agent so that the foam flame retardation is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a preparation method of a toughened and reinforced phenolic foam insulation material, which belongs to the category of synthetic polymer materials. The toughened and enhanced phenolic foam heat insulation material prepared by the invention can be used for heat insulation of building exterior walls, ventilation pipes, petrochemical pipes, electrical appliances, instruments and other industries. Background technique [0002] Foam plastics such as polystyrene, polyethylene, and polyurethane are widely used in the fields of thermal insulation of building exterior walls, ventilation pipes, and petrochemical pipeline insulation due to their low thermal conductivity, light weight, and convenient construction. However, several foam plastics widely used at present, such as polyurethane and polystyrene, have shortcomings such as flammability, large smoke generation, high toxicity, and low heat-resistant temperature, making them widely us...
