Abstract

The invention discloses an insulation board taking waste plastics as raw materials. The insulation board is characterized by comprising the following components in percentage by mass: 25-36 percent of waste plastics, 18-27 percent of fiber, 26-40 percent of filler and 8-12 percent of flame retardant. The insulation board has good thermal insulation and flame retardant property and is safe, environmentally-friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a thermal insulation board made of waste plastics and a preparation method thereof. Background technique [0002] In order to reduce the energy consumption of buildings, thermal insulation materials are generally used on the surface of the maintenance structure of buildings, but for a long time, no thermal insulation materials suitable for building exterior walls have been found. The flammability is poor, and the blowing agent is expensive. Although the inorganic fiber rock wool and glass wool have good flame retardancy, they are very easy to absorb water and the thermal insulation performance drops sharply. Due to the huge amount of building exterior wall insulation materials used, it has been an urgent technical problem to be solved in the field of construction and materials to develop a low-cost, thermal insulation and flame-retardant building ext...
