Description
Technical field
It is especially a kind of with thermoplastic polyurethane coating the present invention relates to a kind of pvc coating cloth technical field
The processing method of paste polyvinyl chloride cloth.
Background technology
Coating cloth is primarily referred to as on the basis of cloth being coated with one layer of material with specific function using special process, makes
Cloth adds special function, so also referred to as functional coat fabric.Polyvinyl chloride abbreviation PVC, is being triggered by vinyl chloride
The thermoplastic resin being polymerized under agent effect, is the homopolymer of vinyl chloride, PVC is the white powder of impalpable structure, branched
Degree is smaller.PVC has the characteristics that fire-retardant, solvent resistant, heat-resisting, comprehensive mechanical property is good, is widely used in packaging material, artificial
The hard product such as the soft goods such as leather, plastic products and tubing, profile shapes, plate, but PVC is poor to the stability of light and heat, 100
More than DEG C or through a long time exposure in sunshine, it will decompose and produce hydrogen chloride, and further autocatalysis is decomposed, and causes discoloration,
Physical mechanical property also declines rapidly, must be added to stabilizer in practical applications to improve the stability to temperature and light.It is existing
Some pvc coating cloth is in order to increase the folding abrasion-proof and cold-resistant of cloth, and add has thermoplastic polyurethane, i.e. TPU more, and TPU is simultaneous
Have a physical mechanical characteristic of plastic processing performance and rubber, TPU have high intensity, high-modulus, high elongation rate and high resiliency,
The characteristic such as excellent wear-resisting, oil resistant, low temperature resistant, ageing-resistant, coordinates PVC to be used as mixed coating very universal.
