Problems solved by technology

At present, the commonly used explosion-proof heat insulation film is generally composed of multiple layers such as polyester film layer, metal coating layer, adhesive layer, wear-resistant layer, etc. The production process is complicated, and the film layers are bonded by optical glue.
In the process of use, it is found that the adhesion between layers, peeling force and the quality of the overall film are not ideal, and often need to be replaced after a period of use
In addition, there are defects such as poor transparency, poor weather resistance, insufficient UV protection, poor heat insulation effect, and scratch resistance.

Abstract

The invention relates to the technical field of polyurethane synthetic materials, particularly to an explosion-proof heat-insulation TPU film for automobile glass, and a preparation method thereof. The explosion-proof heat-insulation TPU film is prepared from the following raw materials in percentage by mass: 70 to 88 percent of TPU master batch, 5 to 20 percent of polycarbonate, 5 to 10 percent of modified nano tin antimony oxide and 0.2 to 0.8 percent of an antioxidant. The explosion-proof heat-insulating TPU film of the invention has explosion-proof and scratch-resistant properties, is highin light transmittance and has heat-insulating and radiation-proof effects. The invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention belongs to the technical field of polyurethane synthetic materials, and in particular relates to an explosion-proof and heat-insulating TPU film for automobile glass and a preparation method thereof. Background technique [0002] With the rapid development of the modern automobile industry, the demand for explosion-proof insulation films for automobiles is increasing day by day. Automobile glass is an important guarantee for drivers to drive safely. The hot weather in summer will cause the interior of the car to heat up at a high speed in a short period of time. There are potential safety hazards and at the same time, it will also cause harm to health. The safety factor of automobile glass, energy saving and consumption reduction. Reduce heat loss in winter, maintain the temperature inside the car, effectively block ultraviolet rays, reduce glare, and ensure safe and comfortable driving. [0003] The car explosion-proof heat insulation ...
