Abstract

The invention relates to a phenolic foam insulation material improved by glass fiber powder and sericite. The insulation material is characterized by being mainly prepared from the following raw materials: 100 parts of phenolic resin, 2-10 parts of a phenolic resin fluidity improver, 0.5-5 parts of foam stabilizer, 1-10 parts of toughening / reinforcing agents, 6-15 parts of a foaming agent and 6-55 parts of a reactive acid curing agent. The insulation material disclosed by the invention, which adopts polyoxyethylene grafted or blocked water-based methyl silicone oil as the foam stabilizer, is delicate and uniform in foam cells, low in heat conductivity coefficient and good in insulation performance; and the insulation material, by taking the glass fiber powder and the sericite as the toughening / reinforcing agents, can be used for reducing the cost, improving the flame retardation of foam and reducing the smoke density.

Description

technical field [0001] The invention relates to a preparation method of a phenolic foam insulation material, which belongs to the category of synthetic polymer materials. The phenolic foam thermal insulation material prepared by the invention can be used for thermal insulation of building exterior walls, ventilation ducts, petrochemical pipelines, 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 used in building exterior walls, ship pi...
