preparation example Construction

[0036] The preparation method of the elastic rotating body of the present invention is carried out according to the following specific steps:

[0037](1) Internal mixing: POE, EPDM rubber, anti-shrinkage agent, filler, EVA, stearic acid, zinc stearate, zinc oxide, crosslinking agent, foaming agent, flow agent, masterbatch pigment Add it into the internal mixer for mixing and stirring, then put the stirred material into the internal mixer for 8 to 12 minutes at a temperature of 80-100°C, put it into the open mixer for uniform tableting, and then granulate. Among them, the kneading temperature is controlled within the range of 45-65°C, the kneading time is controlled within the range of 5-8 minutes, and the granulation temperature is controlled within the range of 80-100°C;

[0038] (2) Plasticizing processing: input the above granulated materials into the barrel of the injection machine for plasticizing processing, and the temperature is controlled within the range of 70-100°C;...

Abstract

The invention discloses a production formula and a preparation method for an elastic rotator, which belong to the technical field of road transportation equipment. The formula comprises the following specific components: 10 to 20 percent of ethylene-octene copolymer (POE), 40 to 60 percent of EVA (ethylene-vinyl acetate copolymer), 10 to 20 percent of ethylene-propylene-diene monomer, 5 to 10 percent of anti-shrinking agent, 1 to 3 percent of filler, 0.6 to 1.6 percent of dispersed lubricant, 1 to 2 percent of zinc oxide, 0.7 to 1.2 percent of cross-linking agent, 1.5 to 2.5 percent of foaming agent, 1.5 to 2.5 percent of flowable agent and 2 to 4 percent of color masterbatch pigment, and the total weight is 100 percent. The POE, the ethylene-propylene-diene monomer and the EVA are mixed and refined, and are added with a variety of additives, so that the three types of materials keep respective properties and complement one another, the elasticity of the prepared elastic rotator is high, moreover, after foaming, the texture is dense, the weight is light, the good anti-aging property of the elastic rotator is ensured, the elastic rotator cannot be easily cracked when receiving impact force, and the service life of the elastic rotator is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of road traffic equipment, and more specifically relates to a production formula and a preparation method of an elastic rotating body. Background technique [0002] With the rapid development of economy, automobiles are widely used as a convenient means of transportation. In my country, the speed limit of different roads is also different. For example, the general speed limit of urban roads is 40 kilometers per hour, the general speed of ordinary roads is 40-80 kilometers per hour, and the general speed limit of expressways is 60-120 kilometers per hour. Therefore, traffic accidents in urban areas are mostly rear-end collision accidents. On ordinary roads or expressways, traffic accidents occur frequently due to excessive speed of vehicles. On the guardrail, and these guardrails are made of concrete bricks or concrete blocks arranged at intervals and cross rails connecting adjacent blocks, or are composed of ...
