Problems solved by technology

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 brings troubles to people's production and life; at the same time, people living in modern high-rise buildings, The noise of the water flow in the downpipes produced by the intensive use of kitchen and bathroom drainage in the morning, middle and evening makes people living in the middle and low floors complain and suffer deeply, and cannot make people live in a relatively quiet and overflowing home living environment.
However, the performance of the current thermal insulation sheet is still unsatisfactory. How to improve the thermal insulation and thermal insulation performance of the thermal insulation sheet is an urgent problem that many building material manufacturers need to solve

Embodiment 1

[0019] The preparation process of thermal insulation composite sheet, the steps are as follows,

[0020] ①. Raw material preparation: prepare raw materials according to the following raw materials and parts by weight, wherein,

[0021]

[0022] ②. Mixing: Weigh the above raw materials according to the ratio and put them into a high-speed mixer to mix evenly. When mixing, the temperature in the high-speed mixer is controlled at 60-75°C;
