Problems solved by technology

In particular, small chemical companies and small refineries refine oil from waste tire rubber, waste plastics, waste lubricating oil, and waste residue oil. The quality of finished gasoline, diesel, fuel oil, etc. is not up to standard, and the content of sulfur, nitrogen, oxygen, etc. is high, which not only causes economic losses to the society but also has adverse effects on the environment.

Abstract

The invention discloses a production method of an environment-friendly modified polymer asphalt resin for road material waterproof coiled material. The method comprises the following steps: (1) according to the following percentages, the pretreated raw materials and additives are statically mixed in a tubular Mixing in the container; (2) Put the mixed material into the liner reactor for heating and stirring; (3) Seal the feeding port of the reactor, vacuumize the pressure at -0.06-0.08mpa, gradually increase the stirring speed as the temperature rises, and vacuumize The pressure is -0.09-0.1mpa, and when the temperature rises to 100°C, remove the water, stop vacuuming, and react for 4-5 hours at a reaction temperature of 180°C and a reaction pressure of 0.03-0.04MPa; (5) The material to be reacted becomes After the paste-like viscous body, the product is sampled and tested, and the asphalt resin product is obtained when the material is discharged. The invention effectively alleviates the pressure of environmental protection, effectively regenerates and recycles solidified waste, "turns waste into treasure", saves energy and reduces emissions, and protects the environment.

Description

1. Technical field [0001] The invention belongs to the technical field of resin synthesis, and in particular relates to a production method of an environment-friendly modified polymer asphalt resin for road raw materials and waterproof coiled materials. 2. Background technology [0002] Solidified waste, such as waste coils, waste plastics, waste rubber, waste lubricating oil, waste rubber, and waste oil, the government invests a lot of money every year in deep burial and incineration. Deep burial is not only a serious waste of precious land resources, but also a large amount of accumulation will cause Carbon monoxide is produced, and in severe cases, a huge explosion may occur. Incineration not only enters a large amount of harmful gases such as sulfide into the atmosphere and directly destroys the ozone layer, but also increases the pollution of air particulate matter with a pH value of 2.5, which is an important source of pollution. In particular, small chemical companie...
