Preparation process of thermal insulation composite sheet material

Abstract

The invention discloses a preparation process of a thermal insulation composite sheet material, which comprises the steps of: preparing materials, mixing, milling, calendering into sheets, compounding, rolling and packaging. The invention has the advantages of simple preparation process, low production cost and low processing difficulty, effectively improves the sheet sound insulating quantity, photo-thermal radiant reflectance and coefficient of heat conductivity, enhances the product performance, provides effective safeguard for the building thermal insulation, integrates compounding and calendering steps into a whole, saves working procedures and the investment in production equipment, reduces the production cost for the industries, and increases the additional value of products.

Description

technical field

[0001] The invention relates to a preparation process of a waterproof building material, in particular to a preparation process of a thermal insulation composite sheet. Background technique

[0002] Environmentally friendly and energy-saving high-tech products are currently the leading products that are being vigorously developed by all countries. Among them, thermal insulation products are one of the important products for energy conservation, especially various thermal insulation sheets or coils currently used in construction projects, such as: various types of auditoriums, theaters, concert halls, conference halls Building facilities such as national defense military facilities and scientific research institutions all have higher requirements for heat preservation and heat insulation. In winter, industrial or civil water supply and drainage pipes are attacked by severe cold, and the water flow in the pipes often freezes, freezes, bursts, etc., which bring...
