A three-dimensional embossed graphene PU tire manufacturing method and equipment

Abstract

The invention discloses a method and equipment for manufacturing a three-dimensional embossed graphene PU tire. According to the method, a polyurethane material is mixed with a certain amount of graphene; two extruders are used for plastifying a graphene and PU composite material; the tire body is coated for four times; the first layer of a contact rim is a graphene and PU mixed material; after the first layer is extruded out, a flow concentrator is supplied with a certain amount of supercritical nitrogen; foamed graphene PU inside which tiny air bubbles are formed is prepared by using a laminator by means of mixing and extrusion; the first layer is adhered with a second layer and a third layer, wherein the second layer and the third layer are made from the foamed graphene PU material; the four layers are made from the graphene PU material; during a material adhesion process of the four layers, an upper pressing roller and a lower pressing roller are used for compacting each layer; finally a hot pressing plate with tread patterns is driven by an oil cylinder in order to emboss the tread patterns on the tire body. The manufacturing method and the manufacturing equipment disclosed by the invention can be used for manufacturing a graphene PU foamed tire; the polyurethane material is mixed with a certain amount of graphene and supercritical nitrogen tiny air bubbles, so the prepared PU tire is elastic, capable of conducting heat and more comfortable.

Description

technical field [0001] The invention mainly relates to the field of tire preparation, in particular to a method and device for manufacturing a three-dimensional embossed graphene PU tire, where PU is polyurethane. Background technique [0002] With the rapid development of the modern automobile and aviation industries, the requirements for tire performance are also constantly increasing. Traditional tires mainly use rubber materials, such as radial tires and bias tires. However, due to its own characteristics, traditional pneumatic tires inevitably have some problems, such as punctured tires, complicated manufacturing and molding processes, and inability to resist the impact of light weapons in the military field. Contradictions, multi-objective optimization cannot be achieved. Some polyurethane tires gradually appear on the market. At present, polyurethane tires mostly adopt solid structures. The manufacturing methods of polyurethane tires disclosed in Chinese patents (pu...

However, due to its own characteristics, traditional pneumatic tires inevitably have some problems, such as punctured tires, complicated manufacturing and molding processes, and inability to resist the impact of light weapons in the military field. Contradictory, can not achieve multi-objective optimization

Some polyurethane tires gradually appear on the market. At present, polyurethane tires mostly adopt solid structures. The manufacturing methods of polyurethane tires disclosed in Chinese patents (publication numbers CN103786290A, CN105330811A) are all casting molding. speed, prone to damage; at the same time, polyurethane solid tires have poor elasticity, which affects the driving comfort of tires
