Problems solved by technology

At present, the main way to use rubber to improve road performance is to add waste rubber powder to asphalt concrete. There is no use of recycled rubber latex to modify cement pavement and replace asphalt to improve the weather resistance, durability, strength and elasticity of pavement. and plasticity

Embodiment 1

[0030] Preparation of reclaimed rubber latex: 100 parts by mass of reclaimed rubber and 5 parts by mass of polyethylene (density 910kg / m3) were masticated and blended on a rubber mixer, at 55°C for 30 minutes to obtain a reclaimed rubber / polyethylene blend 100 parts by mass of reclaimed rubber / polyethylene blend was mixed with 15 parts by mass of dispersant sodium stearate, masticated and blended on a rubber mixer, at 80°C for 40 minutes, dispersed with water to obtain solid content maintenance In 45% recycled rubber latex. The prepared regenerated rubber latex has a black appearance, fine and uniform, and has not been demulsified after standing for one year. The solidification point of the latex is -1°C, and the particle size is between 0.01 and 1 micron.

[0031] Application of rubber-modified concrete pavement: Mix 100 parts of sulfur, 0.2 parts of potassium hydroxide, 50 parts of activator zinc oxide, 100 parts of anti-aging agent A, 100 parts of accelerator DZ, 25 parts o...

Abstract

The invention discloses a preparing method, application and application method of reclaimed rubber latex. The reclaimed rubber latex is prepared with the emulsion dispersion technology on the basis of the rubber-plastic blending technology. The polyethylene-modified reclaimed rubber is prepared with the rubber-plastic blending technology, performance complementation is achieved, the defect that reclaimed rubber is independently used is overcome, and a novel reclaimed rubber material for improving the performance of the cement road surface is provided for persons. By means of an application of the reclaimed rubber latex in the rubber-modified concrete road surface and an application method thereof, the reclaimed rubber latex can be suitable for the functional modification of the rubber-modified concrete road surface, asphalt is replaced with the reclaimed rubber latex to improve the weather resistance, the durability, the strength, the elasticity and the plasticity of the road surface.

Description

technical field [0001] The invention relates to a preparation method and application of regenerated rubber latex, belonging to the field of waste recycling in the field of environmental protection. Background technique [0002] my country is a big rubber consumption country, and its annual consumption of rubber ranks first in the world for 11 consecutive years; it is also a country with a shortage of rubber resources. Today, when natural resources are increasingly scarce and energy is extremely scarce, take the road of recycling waste rubber in China, recycle waste rubber, make good use of it, turn waste into treasure, turn harm into profit, and use its products and extended products as important regeneration Resources are widely used in the fields of rubber, transportation and construction, and it has become a very serious problem to realize the circular economy and sustainable development of my country's rubber industry, which has important practical significance. [0003]...
