Embodiment Construction
[0021] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments:
[0022] The present invention produces the process of wear-resisting, low-temperature, flame-retardant, corrosion-resistant and environment-friendly PVC rubber compound, and its production process is as follows:
[0023] (1) Select 30 parts of polymeric polymer plasticizer, first heat it in the container at a constant temperature of 50-60°C for 10-20 minutes, put the mass fraction of high-polymerization degree polyvinyl chloride resin 100 into the container, and then put the mass fraction Add the calcium zinc stabilizer 8 and stir at a medium speed for 3 to 8 minutes;
[0024] (2) Add the mass fraction of low-temperature resistant plasticizer 15, flame retardant 6, synergist 10, and slip agent 0.8 to the mixture in the first step, stir at high speed for 3-6 minutes, an...

Abstract
The invention discloses a production process for a wear-resistant low temperature-resistant flame-retardant anticorrosive environment-friendly PVC rubber compound. The process comprises the following steps: weighing 30 parts of a polymerized high-molecular plasticizer, heating the polymerized high-molecular plasticizer in a container under a constant temperature in a range of 50 to 60 DGE C for 10 to 20 min, putting 100% by mass of a PVC resin with a high degree of polymerization in the container, adding 8% by mass of a calcium-zinc stabilizing agent, and carrying out middle-speed stirring for 3 to 8 min; then adding 15% by mass of a low temperature-resistant plasticizer, 6% by mass of a fire retardant, 10% by mass of a synergist and 0.8% by mass of a lubricating agent into a mixture obtained in step 1, carrying out full stirring and heating an obtained mixture to a temperature of 120 to 150 DEG C; adding 15% by mass of the low temperature-resistant plasticizer and 15% by mass of a cold resistant agent into the mixture obtained in step 2 and carrying out low-speed stirring; and putting a mixture obtained in step 3 to an extruder for extrusion. The environment-friendly PVC rubber compound prepared by using the production process has the advantages of abrasion resistance, resistance to a low temperature of -65 DEG C, resistance to a high temperature of 135 DEG C, flame retardation, resistance to corrosion by gasoline, machine oil and diesel oil, environment friendliness, no o-benzene and no phosphorus.
Description
technical field [0001] The invention relates to a process for producing PVC rubber material, in particular to a process for producing a PVC rubber material capable of abrasion resistance, low temperature resistance, flame retardancy, corrosion resistance and environmental protection. Background technique [0002] PVC rubber is a material produced from vinyl polymers. In actual use, PVC rubber is often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact-resistant agents and other additives. It has non-flammability, high strength, resistance to climate change and excellent geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. PVC rubber material is widely used, with good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics, mainly used in the production of: cards, OEM, PVC wire, PVC curtains, PVC coated welded wire mesh, PVC foam board , p...
