Abstract
The invention relates to a method for preparing coumarone resin. The method includes the steps that 1, 90% ethylene grease treated to release from a stable water-in-oil state, 9% waste mineral oil and 1% concentrated sulfuric acid are added into a stirred tank type reactor; 2, the pressure in the stirred tank type reactor is kept at 0.1-0.3 Mpa, and the temperature of the stirred tank type reactor is 156 DEG C-165 DEG C; 3, the stirring speed of the stirred tank type reactor reaches 20-40 r/min, and the reaction is kept for 0.8-1.2 h until a drawn-filament-shaped product appears. The method has the advantages of being good in effect, free from by-products and low in cost, and the product is high in added value and environmentally friendly.
Description
Technical field
The present invention relates to a kind of method making coumarone indene resin.
Background technology
Coumarone, also known as indene resin, coumarone-indene resin, coumarone resin, cumarone resin, is commonly called as coal tar resin.Coumarone indene resin obtains through catalytic polymerization for raw material with ethylene bottom oil, carbon nine, and product appearance is yellow, brown, black blocks of solid, has good intermiscibility, water tolerance, resistance to acids and bases, antirust and electrical specification.Feature of environmental protection material coumarone petroleum resin are widely used in the industries such as rubber, tire, wire belt, conveying belt, paint, ink, waterproof, sebific duct, the performance of its uniqueness, and won common concern and the accreditation of rubber synthesis circle personage, produce market is very wide.But there is long reaction time in existing coumarone indene resin making processes, the problems such as the raw materials cost height of needs.
After its stable water-in-oil state abolished by ethene " butter ", gained oil phase main component be C8 ~ C16 containing oxygen unsaturated hydrocarbons, directly can do fuel, but its economic use value is low, novel coumarone indene resin method processed can be used in by processing further, can rise in value to ethene " butter " after process.
Summary of the invention
The object of the invention is to a kind of method that novel coumarone indene resin processed is provided for prior art Problems existing.The inventive method have effective, low without byproduct, cost, product increment is high and the feature of product environmental protection.
Technical scheme of the present invention is:
A method for coumarone indene resin processed, comprises the steps: the first step: by 90% through removing the ethene " butter " after its stable water-in-oil state processing, the useless white oil of 9%, the vitriol oil of 1% be put in stirred-tank reactor; Second step: the pressure in stirred-tank reactor is remained 0.1-0.3Mpa, temperature is 156-165 DEG C; 3rd step, makes the stirring velocity of stirred-tank reactor reach 20-40r/min, keeps reaction 0.8 hour-1.2 little of there being wire drawing shape product to stop.。
Preferably, the pressure in described second step in stirred-tank reactor remains 0.1-0.2Mpa, and temperature is 160 DEG C.
Concrete, in described 3rd step, the stirring velocity of stirred-tank reactor reaches 30r/min, keeps reaction 1 hour.
The beneficial effect of sulfur method provided by the invention is: it is short that 1 coumarone indene resin processed compares the tradition coumarone indene resin time processed, and tradition coumarone indene resin processed needs at high temperature 2-3h, and method coumarone indene resin method provided by the invention only needs 0.5-1h; 2 costs are low, and required several raw materials are cheap starting material, and tooling cost is also low; Product value-added effect is good, using being originally used as the low ethene " butter " of the economic use value of fuel as the raw material of novel coumarone indene resin method processed, improves its economic use value; Raw material makes full use of utilization, and the isolated front-end volatiles of reaction can make light oil and use, and that stays reactor directly makees ethene " butter ", produces without by-product and direct refuse, environmentally friendly.
Embodiment
Embodiment 1

Embodiment 2
Remain 0.1Mpa with embodiment 1 unlike by the pressure in stirred-tank reactor, temperature is 165 DEG C; 3rd step, makes the stirring velocity of stirred-tank reactor reach 40r/min, and keep reaction 1.2 little of there being wire drawing shape product to stop, product meets the requirements.
Embodiment 3
Remain 0.3Mpa with embodiment 1 unlike by the pressure in stirred-tank reactor, temperature is 156 DEG C; 3rd step, makes the stirring velocity of stirred-tank reactor reach 20r/min, and keep reaction 0.8 little of there being wire drawing shape product to stop, product meets the requirements.
