Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0038] see Figure 1-2 Shown, the present invention is the production technology of nitrile butadiene rubber scrap recycling, comprises the following steps:
[0039] S1: The leftover material weighs 30kg, puts it on the material rack 4, and pushes the material rack 4 to the feeding conveyor belt assembly 3;
[0040]S2: Workers put the leftover material on the material rack 4 into the feeding conveyor belt assembly 3, and transport it to the feeding hopper 2 through the feeding conveyor belt assembly 3. After being rolled by the rolling mechanism 7, the leftover material falls on the discharge conveyor On the belt assembly 8, it is transported out of the chassis 1 through the discharge conveyor belt assembly 8, and then falls on the feed conveyor belt assembly 3 through the in...

The invention discloses a production process for recycling nitrile butadiene rubber leftover materials, and relates to the technical field of chemical raw material regeneration. The method comprises the following steps of S1, weighing 30 kg of leftover materials; S2, after the leftover materials are circularly rolled for five times through a rolling mechanism, adding 0.7 kg of regenerated raw material rubber materials and 100 g of foaming raw materials; S3, then circulating rolling through the rolling mechanism; S4, stopping rolling after the surface of the material is exposed to light and ispervious to light; and S5, storing for 2 days, and extruding and filtering impurities through a filtering extruder. The invention adopts a process ratio of 30 kg of leftover materials, 0.7 kg of regenerated raw material rubber materials, 100 g of foaming raw materials, 75 kg of nitrile rubber new materials and 8 kg of plasticizers, and further discloses a nitrile rubber leftover material recyclingdevice, the new materials and old materials are mixed and repeatedly rolled to obtain regenerated raw materials, so that the nitrile rubber leftover materials can be utilized, the production cost isreduced, and the utilization of resources is increased.
Description
technical field [0001] The invention belongs to the technical field of chemical raw material regeneration, and in particular relates to a production process for recycling scraps of nitrile rubber, and also relates to a recycling device for scraps of nitrile rubber. Background technique [0002] Nitrile rubber is nitrile rubber. Nitrile rubber is made from butadiene and acrylonitrile by emulsion polymerization. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, and heat resistance. Good sex, strong adhesion. Nitrile rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms and large oil bags, etc. It is also used to make rubber sheets and wear-resistant parts. It is mainly used in automobile, aviation, printing, textile and machinery manufacturing industries abroad. Due to the development of modified varieties of nitrile rubber, the application ...
