Problems solved by technology

It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc. PVC products are made of PVC rubber It is processed and made, but there are still deficiencies in the existing formula of PVC rubber production. In the process of producing PVC rubber, the best flame retardant effect is very poor, and the rubber is easy to white and foam. As a result, the quality of subsequent PVC products is poor, such as low flame retardant effect, etc.

Abstract

The invention relates to the technical field of modified flame-retardant PVC sizing materials, in particular to a formula of a modified flame-retardant PVC rubber material. A method comprises the following steps: S1, selection: selecting raw materials of the modified flame-retardant PVC rubber material: SG-5 PVC resin, DINP diisononyl phthalate, a stabilizer, a TD-350 filler, a flame retardant, EP-18 epoxy resin, calcium stearate, light calcium carbonate, antimonous oxide, magnesium hydroxide and titanium dioxide; and S2, weighing: weighing the selected modified flame-retardant PVC rubber formula raw materials in parts by weight by using instruments respectively: SG-5 PVC resin, DINP diisononyl phthalate, a stabilizer, a TD-350 filler, a flame retardant, EP-18 epoxy resin, calcium stearate, light calcium carbonate, antimonous oxide, magnesium hydroxide and titanium dioxide. The SG-5 PVC resin and the DINP powder diisononyl phthalate are blended, the TD-350 filler is used, the antimonous oxide and the magnesium hydroxide flame retardant are matched to achieve the optimal flame retardant effect, and the rubber material does not whiten or foam.

Description

technical field [0001] The invention relates to the technical field of modified flame-retardant PVC rubber, in particular to a formula of modified flame-retardant PVC rubber. Background technique [0002] PVC used to be the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc. PVC products are made of PVC rubber It is processed and made, but there are still deficiencies in the existing formula of PVC rubber production. In the process of producing PVC rubber, the best flame retardant effect is very poor, and the rubber is easy to white and foam. As a result, the quality of subsequent PVC products is poor, such as low flame retardant effect. [0003] To sum up, the present invention proposes a modified flame-retardant PVC compound formula to solve th...
