Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes. The chlorination degree of CPs can vary between 30 and 70 wt%. CPs are subdivided according to their carbon chain length into short chain CPs (SCCPs, C10–13), medium chain CPs (MCCPs, C14–17) and long chain CPs (LCCPs, C>17). Depending on chain length and chlorine content, CPs are colorless or yellowish liquids or solids.

The invention provides a wear-resistant anti-aging waterproof tarpaulin and a preparation method thereof, and belongs to the technical field of tarpaulin. The wear-resistant anti-aging waterproof tarpaulin comprises a base cloth layer and a PVC (polyvinyl chloride) coating coated on the base cloth layer, wherein the PVC coating is prepared from the following raw materials: 70 to 90 parts of PVC paste resin, 5 to 15 parts of a composite plasticizer, 10 to 30 parts of TiO2-HNTs powder, 3 to 5 parts of chlorinated paraffin, 8 to 12 parts of an additive and 80 to 100 parts of a solvent. The titanium dioxide and the halloysite nanotubes are compounded, the titanium dioxide is loaded on the halloysite nanotubes, agglomeration of the titanium dioxide is prevented, and the mechanical property and wear resistance of the tarpaulin can be effectively enhanced by adding the halloysite nanotubes.

Non-chlorine system gear shaving process oil composition and preparation method and application thereof
The invention discloses a non-chlorine system gear shaving process oil composition. The raw materials include, by mass, 75% to 85% of mineral base oil, 2% to 10% of anti-wear agent, 2% to 10% of extreme pressure agent, 5% to 10% of oiliness agent, 0.1% to 0.5% of antioxidant, 0.4% to 1% of rust inhibitor, 0.1% to 0.5% of corrosion inhibitor, and 20-50 ppm of anti-foaming agent. The non-chlorine system gear shaving process oil composition has the same excellent lubricating extreme pressure performance as a chlorinated paraffin system without using chlorinated paraffin or other chlorine agents, solves the practical problem of chlorinated paraffin being commonly used in gear shaving process oils, has better lubricity and service life, and improves the processing precision of gear shaving parts.
