Problems solved by technology

It has the advantages of fast vulcanization speed and good scorch resistance; due to the characteristics of reclaimed rubber itself, its current main use is still limited to the rubber product industry, and there are also some applications in other industries, but they are relatively few, and its application fields still need to be developed
[0006] Making reclaimed rubber into foamed materials can greatly improve the utilization rate of reclaimed rubber. However, at present, the use of reclaimed rubber to prepare foams is mainly molded products, which has low production efficiency, high labor intensity, and unstable product performance. The production capacity of continuous vulcanization and foaming, so it is of great significance to study a method of producing foam materials from reclaimed rubber with low production cost, good product performance and stable quality

Embodiment 1

[0035] The tire reclaimed rubber microwave continuous foaming board was prepared by the following process steps.

[0036] (1) Adjust the roller distance of No. 1 mill to 0.3mm, put in the reclaimed rubber material and pass it thinly, make a triangle bag, and pass it 4 times; then adjust the roller distance of No. 1 mill to 3mm, and put in the The rubber material processed in the step is covered with rolls, and the surface is smooth and free of bubbles, and the film is lowered to make a film; the film is forced to cool to room temperature with an industrial fan, and parked for more than 24 hours;

[0037] (2) Mix the cooled film and aromatic oil according to the ratio of 8 parts of aromatic oil per 100 parts of rubber, and put it into No. 1 internal mixer for mixing, so that the reclaimed rubber and aromatic oil are fully mixed; when No. 1 internal mixer When the temperature reaches 80°C, add 0.8 parts of paraffin, 1 part of stearic acid, and 1 part of polyethylene glycol-4000 ...

Abstract

A microwave continuous foaming plate of tire reclaimed rubber is made from material which comprises reclaimed rubber, sulfur powder, zinc oxide, accelerating agent, paraffin, stearic acid, polyethylene glycol-4000, antioxidant, and foaming agent. The preparation method comprises the following steps: a. thinning reclaimed rubber material, then adding the processed rubber and aromatic oil in an open mill to mix; (b) adding paraffin, stearic acid and polyethylene glycol into the rubber in turn at 70-90 degree Celsius, and the processed rubber discharging, calendering at 110-130 degree Celsius, and then cooling, (c)adding sulfur powder, zinc oxide and other additives in the rubber in turn to mix, and then calendering. The processed rubber is foamed and vulcanized in a microwave hot air circulating oven. The plate is cheap, and good in performance. The preparation method which can be done continuously has high yield and low labor intensity.

Description

technical field [0001] The invention relates to the application of reclaimed rubber, in particular to a foam produced by using reclaimed rubber and a preparation method thereof, belonging to the technical field of reclaimed rubber utilization. Background technique [0002] In the field of polymers, the application of foam materials has become more and more extensive, such as polystyrene foam board, polyvinyl chloride foam insulation board, polyurethane foam glue, etc. Due to the porosity of the foam material, it can absorb high energy during the compression process, so it is widely used in packaging, protection and other fields. However, there are still some defects in the preparation of some foam materials, such as environmental protection defects, continuous production of products and other problems, which make the development of foam materials subject to certain restrictions. [0003] For example, expanded polystyrene (EPS) was often used for packaging in the past, and E...
