Preparation process of heat insulating material

Abstract

A preparation process of a heat insulating material includes the steps: S1 preparing foam plastics and placing depleted foam plastics in a crusher for crushing to prepare foam plastics with the size of 2-6mm for standby application; S2 preparing heat insulation fibers, throwing fiber depleted heat insulating materials into solution containing sulfonate surfactants, soaking and softening the fiber depleted heat insulating materials, powerfully tearing the materials by mechanical force and further loosening the fiber depleted heat insulating materials into fibers; S3 preparing mixed slurry; S4 placing the mixed slurry in a closed die, increasing the temperature of the die to 120-180 DEG C, sintering the die for 1-3 hours, cooling the die to room temperature and then releasing the die to obtain the heat insulating material. The prepared heat insulating material has the advantages of excellent heat insulating and flame-retardant performances and the like, environmental friendliness, huge market potential and wide prospect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a preparation process of thermal insulation materials. Background technique [0002] With the deepening of global energy and resource shortages and environmental pollution, saving energy and resources has become the only way for global economic development. The Chinese government has also publicly stated many times on various official occasions that energy conservation, emission reduction and sustainable development should be regarded as the basic national policy of China's economic development. According to reports, the energy consumption of housing construction accounts for about 25-40% of my country's total energy consumption. Therefore, doing a good job in energy saving and emission reduction of housing construction is of great significance to implement the basic national policy of energy saving, emission reduction and sustainable economic development pr...

Problems solved by technology

[0003] Construction is one of the fastest-growing sectors of energy consumption in my country, and its energy consumption has accounted for 27% of the country's total energy consumption, especially the insulation materials for building exterior walls. Affects energy consumption, so the main task of the construction industry as a large energy consumer is to reduce energy consumption and improve energy utilization while improving the insulation performance of materials; at present, the insulation materials used in external wall insulation projects are mainly based on Organic flammable materials represented by polystyrene foam have serious fire hazards

At the same time, it is prone to stress concentration, cracking, poor air permeability and other defects, and its life is limited, which is difficult to meet the use requirements
