Problems solved by technology

[0003] Connectors need to be replaced after their service life is reached, and the replaced scrapped connectors need to be destroyed. The existing connector shells are generally made of non-degradable plastics, because the non-degradable plastics of the connector shells contain A large amount of toxic substances, directly discarded into nature will produce a large amount of toxic substances, which are not easy to degrade and will pollute the atmosphere and soil. Therefore, we propose a process for making connectors from degradable materials

Abstract

The invention discloses a process for making a connector by degradable materials. The process comprises the following steps: S1, ingredients: polylactic acid, starch, cellulose, a resin material, andan additive; and S2, mixing the ingredients: weighing polylactic acid, starch, cellulose, the resin material and the additive according to proportion, adding starch, cellulose and the resin material to a plastic mixer, starting the plastic mixer, successively adding the additive, polylactic acid and cellulose, and performing thorough mixing. The process uses polylactic acid, starch, cellulose andother components as the plastic raw materials for making the connector for production, and the connector can be self-degraded after being scrapped since polylactic acid, starch and cellulose are all degradable materials. Moreover, the degradable plastic made of polylactic acid, starch and cellulose does not cause pollution when being degraded, and the produced connector has all the characteristicsand properties of an original connector, and is degradable and non-pollution after degradation.

Description

technical field [0001] The invention relates to the technical field of connector production, and more specifically relates to a process for making connectors from degradable materials. Background technique [0002] The connector is composed of two parts, namely the plug-in and the connector, which can be completely separated under normal conditions. The similarity between the switch and the connector lies in the change of the contact state of the contact pair to realize the conversion of the connected circuit. The essential difference is that the connector has only two states of insertion and removal, the switch can realize the conversion of the circuit on its body, and the connector can also be called a connector. With the progress of society, electrical appliances are used in people's daily life and Production continues to increase. With the increase of electrical functions, there are more and more internal wire connections. As a convenient and fast connector, connectors a...
