Benefits of technology

This patented technology uses two types of materials: rare earth or metallic stabilizers with specific chemical structures for better heat dissipating properties during manufacturing processes while also improving their overall durability against environmental factors such as sunlight exposure over time. Chlorination polymers are used instead of traditional rubber elastomer components like styrene/butadiene rubbers (SBR) which help prevent degrading these products due to long term outdoor storage conditions at high temperatures. Additionally, it suggests adding certain compounds called chlorineized polythiols and vinyl laurate dimmers may further enhance its effectiveness by reducing melting point and increasing flexural rigidity. Overall, this combination makes the material more resistant to damage from extreme environments than previously possible without added ingredients.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the properties of polymer compositions like vinylchloride without compromising their physical integrity or being harmful for human health. Existing solutions have limitations with regards to flexibility, durability, weather resistance, chemical stability, cost effectiveness, etc., making them difficult to meet these standards required for various applications where they may require strong mechanical support while maintaining good barrier characteristics against moieties like gases.

Abstract

The invention relates to the technical field of polyvinyl chloride (PVC) composite materials, in particular to an ultraviolet-proof environmental-friendly PVC modified material and a preparation method of the ultraviolet-proof environmental-friendly PVC modified material. The modified material is composed of, by weight, 80-120 parts of PVC resin, 30-70 parts of filling agents, 41-80 parts of plasticizer, 1-10 parts of fire retardant, 1-10 parts of stabilizer, 5-15 parts of impact modifier, 0.2-2 parts of lubricating agents, 0.5-1.5 parts of light stabilizer and 0.2-1 part of antioxidant. The preparation method comprises the steps of weighing the raw materials according to the parts by weight, mixing the raw materials, after stirring, extruding prills through a twin-screw extruder, and obtaining the modified material. The modified material has the advantages of ultraviolet protection and oxygen resistance, service life of the PVC material exposed in air is greatly improved, environment is protected, strength is high, a fire retardant effect is good, compression performance and toughness are strong, processability is good, and an overall property is good.
