Abstract
The invention provides a high-strength environmentally-friendly rubber plate prepared by directly utilizing waste rubber powder and a method for preparing the rubber plate. Components selected by theinvention and the proportion of the components ensure that the rubber plate has good mechanical properties. The tensile strength of the rubber plate is between 3.49 and 5.3, the elongation at break isbetween 94 and 150 percent, and the strength is 66 DEG. The method has the mainly characteristics of using the waste rubber powder to directly produce the rubber plate, and saving working proceduressuch as desulfurization and refining during the production of regenerated rubber. The method saves a large amount of special equipment, factory buildings, power and manpower, and can also save chemical raw materials such as a softening agent, a tackifier and the like; and in addition, no pollution of waste water, waste gas and flying dust generates in the technological process.
Description
Technical field;
The present invention relates to rubber item and preparation technology, specifically a kind of rubber plate that utilizes the waste old preparation and preparation method thereof.
Background technology:
At present, the main method of China's waste rubber utilization is to make reclaimed rubber, is about to waste old through operations such as pulverizing, desulfurization, pressure white silks, and the sulphur in the waste old is thoroughly taken off, and with the elasticity and the plastics of recovery rubber, thereby forms reclaimed rubber.And be the rubber item of feedstock production Cheng Xin with this reclaimed rubber.This method exists production energy consumption big, the shortcoming that production efficiency is low, the technological process of production is long, and limit in view of present technology and economic condition, all there is the topsoil of low-concentration organic exhaust gas in various degree in the scrap rubber desulfurization regeneration treating processes of China many reclaimed rubbers enterprise.
In order to address this problem, some enterprise has changed rubber powder over to from the reclaimed rubber utilization and has directly utilized the stage at present.There is a certain amount of unsaturated link(age) in vulcanized rubber powder after promptly utilize pulverizing, adds that directly to carry out vulcanizing mold after the sulphur promotor molded.This method technology is simple, cost is low, but can only produce the low grade products not high to mechanical property requirements such as all kinds of pads such as machine pad, roadbed pad, buffering and splash pan, sound absorbent material.
Summary of the invention;
Purpose of the present invention just provides a kind of high-strength environmentally-friendly rubber plate that directly utilizes the waste rubber powder preparation, and a kind of method for preparing this rubber plate is provided simultaneously.
The object of the present invention is achieved like this:
High-strength environmentally-friendly rubber powder rubber plate provided by the present invention is to be made by the component of following weight part ratio:
80～120 parts of waste rubber powders, 0.5～0.8 part of vulcanization accelerator, 0.5～0.8 part of vulcanization leveller, sulphur 1.5～1.7.
Wherein vulcanization accelerator can be selected captax, altax, promotor TT for use.
Vulcanization leveller can be selected zinc oxide or stearic acid for use.
The preferred vulcanization accelerator of the present invention is captax, altax.
The preparation method of high-strength environmentally-friendly rubber powder rubber plate provided by the present invention may further comprise the steps:
A, by weight than taking by weighing: 80～120 parts of waste rubber powders, 0.5～0.8 part 3 of vulcanization accelerator, 1.5～1.7 parts in sulphur.
B, with the waste rubber powder drying and dehydrating:
Mould is gone in c, adding vulcanization accelerator, vulcanization leveller, sulphur, stirring;
D, at 120～160 degree, pressure is～3.4kg f cm～condition under, vulcanized 10～20 minutes.
The component that the present invention is selected and the consumption proportion of each component have guaranteed that prepared rubber plate has the good mechanical performance.
The rubber plate that the present invention is prepared, its tensile strength are 3.49～5.3, and tensile yield is 94-150%, and intensity is 66 degree.
The characteristics of the inventive method maximum are utilized waste and old waste rubber powder direct production rubber plate exactly, can save operations such as desulfurization in the reclaimed rubber production process, refining.Saved a large amount of specific equipments, factory building, power and manpower, also can save industrial chemicals such as tenderizer, tackifier, in addition, there is not the pollution of waste water, waste gas, flying dust in technological process.Adopt its mechanical strength height of rubber plate of this method preparation.Water-permeable and air permeable is good and certain very property arranged.Can be used for preparing the high high-grade rubber item of rubber plate mechanical strength.
Embodiment:
By weight than taking by weighing:
80 kilograms of A, waste rubber powders, 0.8 kilogram of promotor, 0.8 kilogram in zinc oxide, 1.7 kilograms in sulphur.
B, with the waste rubber powder drying and dehydrating;
C, adding promotor, zinc oxide, sulphur stir, and go into mould;
D, 120 the degree, pressure is under the 3.4kg f cm condition, vulcanizes 10 minutes.
Embodiment 2:
A, take by weighing: waste rubber powder 120 kg, 0.5 kilogram of vulcanization accelerator, 0.5 kilogram of stearic acid, 1.5 kilograms in sulphur by proportion part ratio.
B, with the waste rubber powder drying and dehydrating.
C, adding promotor, stearic acid, sulphur stir.
D, at 160 degree, pressure is～3.4kg f cm～condition under, vulcanized 20 minutes.
