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.

Embodiment 1

[0023] Polymerization reaction: (1) According to the following percentages, mix the pretreated raw materials and additives in a tubular static mixer; waste felt paper 40%, waste polyethylene plastic 20%, waste tire 10%, waste lubricating oil 3 %, waste residue oil 10%, natural resin rubber 4%, polyisobutylene 4%, styrene-butadiene-styrene block copolymer 5%, polyimide 3.8%, formamide 0.2%; (2) will Put the mixed material into the liner reactor for heating and stirring at a stirring speed of 15-65 rpm; (3) heat up to 40-50°C, seal the feeding port of the reactor, stir at a stirring speed of 40-45 rpm, and vacuumize The pressure is -0.06-0.08mpa. As the temperature rises, the stirring speed is gradually increased to a maximum of 65 rpm. The vacuum pressure is -0.09-0.1mpa. Under the conditions of temperature 180°C and reaction pressure 0.03-0.04MPa, react for 4-5 hours; (5) After the reaction material becomes a paste-like viscous body, sample and test the product. When the softe...

Abstract

The invention discloses a method for producing environment-friendly modified macromolecular asphalt resin for road raw materials and waterproof coiled materials. The method comprises the following steps: (1) mixing pretreated raw materials and additives in a tubular static mixer according to percentage; (2) putting mixed materials in a lined reactor, and stirring while heating; (3) sealing a feeding port of the reactor, vacuumizing until the pressure is -0.06 to 0.08MPa, increasing the stirring speed along with temperature rise, vacuumizing until the pressure is -0.09 to 0.1MPa, removing moisture when the temperature rises to 100 DEG C, stopping vacuumizing, and reacting for 4-5 hours at the reaction temperature of 180 DEG C and the reaction pressure of 0.03-0.04MPa; (4) sampling and assaying a product after the reaction materials become a paste dilute sticky substance, and discharging, thereby obtaining an asphalt resin product. The method has the advantages that the environmental protection pressure is relieved effectively, solid chemical wastes are effectively recycled, the waste is changed into the valuable, energy is saved, emissions are reduced, and the environment is protected.

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...
