Abstract

The invention relates to a heat and sound insulating material, in particular to a production method and application of a heat and sound insulation explosion preventing film. The heat and sound insulation explosion preventing film comprises three layers of materials, wherein the middle layer is polyvinyl chloride, and both side layers are polyvinyl butyral; an infrared absorbing agent, an ultra-violet absorbing agent, a hindered amine light stabilizer and an antioxidant are respectively added into the middle layer and both side layers; and the infrared absorbing agent is a mixture of nano titanium dioxide and nano calcium hexaboride. In the preparation method, the film is obtained on the basis of a multi-layer coextrusion casting film extruding technology by optimizing the process condition. The heat and sound insulation explosion preventing film is mainly used for being made into laminated glass. The explosion preventing film has favorable heat and sound insulating function and overcomes the defect of easy shrinkage and deformation in the production of traditional plastic films.

Description

technical field [0001] The invention relates to the field of preparation of heat-insulating and sound-insulating materials, in particular to a production method and application of a heat-insulating, sound-insulating and explosion-proof film. Background technique [0002] With the progress of human life and the development of science and technology, people have higher and higher requirements for the quality of life. On the other hand, due to the increasingly significant impact of the global greenhouse effect, the temperature rise is particularly obvious. Furthermore, the development of industrialization has brought Therefore, people are looking for efficient heat and sound insulation materials. At present, there are many materials with heat insulation and sound insulation functions, and there are many forms. Among them, there are relatively few reports on explosion-proof membranes with heat insulation and sound insulation functions. Contents of the invention [0003] Aimin...
