Abstract
The invention discloses high-strength and high-toughness PVC covering cloth. The high-strength and high-toughness PVC covering cloth is formed by coating both sides of woven fabric with a PVC coating. The raw material formula of the PVC coating comprises the following ingredients (by weight): 80 parts of PVC paste resin, 10-30 parts of chlorinated polyethylene, 40-85 parts of dicapryl phthalate, 1-8 parts of titanium dioxide, 1-35 parts of carapace milled powder, 1-4 parts of rubber powder, 3-6 parts of a stabilizing agent and 1-6 parts of an adhesive. According to the high-strength and high-toughness PVC covering cloth, the carapace milled powder, which can adsorb chlorine free radical generated by thermal decomposition of PVC so as to inhibit PVC decomposition subsequently triggered by the chlorine free radical, is added into the PVC coating formula. Therefore, heat stability of the PVC covering cloth is raised, and the PVC covering cloth has lasting strength. In addition, brittleness of the PVC covering cloth is overcome due to the rubber powder added in the formula. The prepared PVC covering cloth has characteristics of high strength and high toughness.
Description
Technical field
The present invention relates to a kind of high-strength and high ductility PVC tarpaulin。
Background technology
PVC tarpaulin is base fabric coated on both sides PVC paste resin。Compared with general PE tarpaulin, PVC tarpaulin rain proofness is much better than PP, PE paulin, all has been widely used in fields such as paulin room, automobile, train, storages。It addition, PVC cost is low, abundance, nontoxic, it is a kind of membrane material being worthy to be popularized。But due to the shortcoming of PVC light, thermally-stabilised difference, PVC tarpaulin in use, particularly uses under sky enthusiasm condition, it is easy to problem of aging occur, affect the intensity of PVC tarpaulin。Although the formula of existing PVC tarpaulin can add light, heat stabilizer to delay this catabiosis, but the addition of light, heat stabilizer is limited, therefore lasting resistant function is not had for the aging of PVC tarpaulin, cause that the intensity of tarpaulin is weakened severely。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of high-strength and high ductility PVC tarpaulin。
For realizing the purpose of the present invention, the technical scheme is that a kind of high-strength and high ductility PVC tarpaulin, it is made up of woven fabric double-coated PVC coating, and the composition of raw materials of described PVC coating includes following components according to parts by weight: PVC paste resin 80 parts, chlorinated polyethylene 10～30 parts, dioctyl phthalate 40 ~ 85 parts, titanium dioxide 1 ~ 8 part, carapace grounds travel 1～35 part, rubber powder 1～4 part, stabilizer 3 ~ 6 parts, binding agent 1 ~ 6 part。
Preferred technical scheme is, the particle diameter of described carapace grounds travel is below 5000 orders。
Preferred technical scheme is, described rubber powder is neoprene, and particle diameter is less than 2 microns。
Preferred technical scheme is, described binding agent is vinylpyridine system binding agent or polyvinyl butyral cementing agent。
Preferred technical scheme is, also comprises uv-resistant agent 0.1 ~ 0.8 part in the composition of raw materials of described PVC coating。
Prior art is compared, high-strength and high ductility PVC tarpaulin of the present invention adds carapace grounds travel in PVC coating formula, it can adsorb the chlorine radical that PVC thermal decomposition produces, suppress the follow-up decomposition causing PVC of chlorine radical, thus improving the heat stability of PVC tarpaulin, PVC tarpaulin is made to have lasting intensity；The rubber powder additionally added in formula overcomes the fragility of PVC tarpaulin；Obtained PVC canopy cloth has the feature of high-strength and high ductility。
