Problems solved by technology

[0004] However, the melting temperature of polyvinyl chloride is not high, and its molding temperature is usually controlled between 150 and 180 degrees Celsius, so the temperature resistance of polyvinyl chloride is poor. In addition, the chemical composition of polyvinyl chloride is carbon, hydrogen, chlorine , when polyvinyl chloride is thermally decomposed, it will produce carcinogenic hydrogen chloride, which will affect human health

Embodiment Construction

[0025] The physical properties of polyurethane thermoplastic elastomer TPU (Thermoplastic Polyurethane) are between plastic materials and rubber materials, and various types of products have been manufactured through continuous research and development and different processes. TPU The nature of the product has been greatly improved and improved with the scope of use and product needs, such as mechanical strength, abrasion resistance, cold resistance, and biocompatibility, etc.; and the scope of application tends to be diversified, such as people’s livelihood, defense industry and medical Sanitary products and other uses.

[0026] If polyvinyl chloride (PVC) is blended with TPU, not only can it effectively reduce the overall chlorine content, but also because of its elasticity, it can replace the function of a plasticizer. The present invention utilizes this technology to produce flame-resistant composite tape.

[0027] Such as figure 1 As shown, the present invention includes a fi...

Abstract

The invention relates to a flame-retardant compound adhesive fabric and a manufacturing method thereof. The manufacturing method comprises the following steps: forming a paste on the surface of an oxidized fiber fabric, wherein the paste comprises 100 parts by weight of polyurethane and 5 parts by weight of isocyanate; then, feeding a compound adhesive containing polyvinyl chloride (PVC) and polyurethane (TPU) into an adhesive fabric machine, forming a compound adhesive film; and finally, bonding the compound adhesive film on the surface of the oxidized fiber fabric through the paste, thus finishing the manufacturing process. According to the invention, under the interaction between the oxidized fiber fabric and the PVC / TPU compound material, the flame-retardant effect is improved multiple times.

Description

Technical field [0001] The invention relates to a composite tape, in particular to a flame-resistant composite tape and a manufacturing method thereof. Background technique [0002] Polyvinyl chloride {PVC, {Poly(vinyl chloride)}} is the most important and most commonly used kind of man-made polymers, mainly because it has great variability and can be used in the process of manufacturing polyvinyl chloride products. According to different purposes and needs, various plasticizers and additives are added to change its physical or chemical properties. [0003] The biggest feature of polyvinyl chloride is that after adding liquid plasticizer, the glass transition temperature (Tg) point will begin to drop. Due to its plasticity, semi-hard to soft materials with a wide range of elasticity can be produced. This is a soft poly The reason why vinyl chloride is practical. Moreover, the processing range of polyvinyl chloride is very wide. By using different polymerization degrees with vario...
