3D blowing membrane

Abstract

The invention discloses 3D blowing membrane. The 3D blowing membrane comprises an annular membrane body, wherein the annular membrane body comprises a TPU membrane layer, an anti-corrosion layer is attached to the upper end of the TPU membrane layer, an anti-impact layer is attached to the upper end of the anti-corrosion layer, a high-tenacity layer is attached to the upper end of the anti-impactlayer, a high-elasticity layer is attached to the upper end of the high-tenacity layer, a low temperature resisting layer is attached to the upper end of the high-elasticity layer, a high temperatureresisting layer is attached to the upper end of the low temperature resisting layer, an antibacterial layer is attached to the upper end of the high temperature resisting layer, and an flame retardinglayer is attached to the upper end of the antibacterial layer. According to the 3D blowing membrane, a common PVC material is replaced by a TPU material, so that the comprehensive performance of theblowing membrane is improved, and the TPU material is non-poisonous and environmentally friendly, has incomparable characteristics compared with other plastics and natural materials, can significantlyenhance characteristics of the strength, the tenacity, wear resistance, ageing resistance, weather change resistance and the like of the blowing membrane and products of the blowing membrane, and then is more suitable for being used for production and lives.

Description

technical field [0001] The invention relates to the technical field of blown films, in particular to a 3D blown film. Background technique [0002] With the development of the times, the improvement of human living standards and the constant pursuit of materials, a variety of inflatable products have been developed, such as 3D products, inflatable toys, balloons, inflatable mattresses, and water inflatable products. Some blown products are mostly made of PVC material. The main component of PVC is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products...

AI Technical Summary

Problems solved by technology

Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings, leather and inflatable products. It is easy to become brittle and difficult to preserve, so its scope of use is limited, and with the improvement of environmental protection awareness, the traditional PVC film is toxic, not cold-resistant, easy to damage after repeated folding, and poor air tightness , poor anti-ultraviolet performance and poor waterproof performance, etc., resulting in poor overall performance, which is not suitable for daily production and use, and is not conducive to the production of blown products. Therefore, we propose a 3D blown film to solve the above problems
