Abstract

The invention discloses a process of producing novel environment-friendly TPU (thermoplastic polyurethane) awning. The TPU awning is obtained by carrying out film spraying on two sides of woven clothby using TPU film spraying liquid. The TPU film spraying liquid is prepared from the following components in parts by weight: 50 to 60 percent of TPU, 5 to 10 percent of fat diisocyanate, 10 to 15 percent of iso-octyl p-methoxycinnamate, 5 to 10 percent of anatase nanometer titanium dioxide, 3 to 8 percent of hydroxypropyl distarch phosphate ester, 1 to 3 percent of abelmoschus manihot gum, 3 to 8percent of alpha-cyclodextrin, 2 to 5 percent of butyl reclaimed rubber, 1 to 4 percent of paraffin oil, 0.5 to 1.2 percent of a lubricant and the balance of purified water. Two surfaces of the wovencloth are coated with glue, and are subjected to two-surface film spraying; the obtained TPU awning is pressed by an inverted L-shaped five-roller wheel group, thus obtaining the finished TPU awningproduct; the technological process is simplified, and the production efficiency is greatly improved; furthermore, the TPU awning has a flat and smooth surface, and is bubble-free, uniform in thickness, firm and durable; the butyl reclaimed rubber in the TPU film spraying liquid is obtained by processing and refining waste butyl rubber tires; waste utilization is realized; meanwhile, the TPU awningis economical and environmentally friendly and also has shock prevention and sound absorption effects.

Description

technical field [0001] This field relates to the field of textiles, in particular to a process for producing a novel environmentally friendly TPU tarpaulin. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) material is an environmentally friendly material that is odorless and easy to process. TPU has excellent characteristics of high tension, high tensile strength, toughness and aging resistance. It has a wide range of hardness (60HA-85HD), wear-resistant , oil resistance, transparency, good elasticity, widely used in daily necessities, sporting goods, toys, decorative materials and other fields. [0003] Such as figure 1 Shown is the traditional process flow chart of tarpaulin production. The weaving is arranged on the cloth rack, and it is transferred to the rubber wheels through the rollers. The adhesive is squeezed between the rubber wheels through the extruder, and the single The surface is coated with glue, after being dried and shaped by the t...
