The invention discloses a nitrile rubber composition with high temperature resistance and compression set resistance and a preparation method thereof, and relates to the technical field of rubber compositions, and the nitrile rubber composition is prepared from the following components in parts by weight: nitrile rubber, zinc oxide, sodium stearate, an enhanced supplementary additive, nano cerium oxide, carbon black, methyl phenyl silicone oil, resin, an anti-aging agent, sulfur and an accelerant. The nitrile rubber composition prepared by the invention is rich in elasticity and rebound resilience; the sealing material has excellent mechanical strength including expansion strength, elongation, tear strength and the like, has the characteristics of good air tightness, high temperature resistance and excellent compression set resistance, and can be suitable for most sealing occasions.

The invention relates to a preparation method of benzoxazine tackifying resin, which comprises the following steps: mixing benzenediol with aniline and paraformaldehyde at 85-95 DEG C to react for 4-7 hours, thereby obtaining the benzoxazine tackifying resin, the benzenediol comprises one or more of resorcinol, catechol and hydroquinone. The benzoxazine tackifying resin can be used for tackifying a rubber composition and has good performance.

This application discloses a fabric for bags and a method for preparing the same, belonging to the technical field of bag fabrics. The bag fabric includes a base layer, an adhesive, and an abrasion-resistant layer. By weight, the abrasion-resistant layer comprises the following raw materials: 60-70 parts PE resin, 15-20 parts modified corn fiber, 4-8 parts coumarone resin, 10-18 parts modified diatomaceous earth, 2-4 parts dioctyl sebacate, 2-6 parts antioxidant, 0.5-1 part calcium stearate, and 1-1.5 parts rosin. The abrasion-resistant layer prepared by this application has good mechanical strength and abrasion resistance. When applied to the surface of the bag fabric, it is not easily worn or torn, thus extending the service life of the bag fabric.
