Problems solved by technology

[0004] But CN99114968.8 described "distillation range components below 120 DEG C are used as softening agent in rubber industry", through practical application, it is found that there is a serious odor defect: because when the rubber industry uses this softening agent to produce rubber products, when rubber products In the thermal vulcanization process, it will always be molded into the mold with a heating range of 140°C to 180°C, then this kind of softener, which is a distillation range component below 120°C, will overflow from the blended product, resulting in thermal vulcanization in rubber product companies. The workshop and the surrounding environment are filled with unpleasant odors
[0005] The oil obtained by thermal cracking of waste rubber / waste plastics should be used, and the oil should be mixed into rubber / plastics as a softener. The thermal vulcanization process does not overflow; the oil that can meet this requirement has not been seen in the literature or on the market

Abstract

The invention provides a waste rubber / plastic pyrolysis oil applicable to rubber / plastic softening or / and as tackifier and a preparation method of the waste rubber / plastic pyrolysis oil. The waste rubber / plastic pyrolysis oil is characterized in A or / and B, to be specific, A, the characteristics of a low temperature distillate limit under 1 atmospheric pressure ranging from room temperature to 140DEG C or 190 DEG C belong to one, or a combination of more than one, of I, II and III, with I, the weight ratio of the distillation fraction heated in the distillation range of 180 DEG C or 190 DEG Cbeing equal to or less than 5%, II, the weight ratio of the distillation fraction heated in the distillation range of 165 DEG C or 175 DEG C being equal to or less than 5%, III, the weight ratio of the distillation fraction heated in the distillation range of 140 DEG C or 160 DEG C being equal to or less than 5%; B, a sample of 3-5 g is kneaded by mixing pure rubber or / and plastic with the weightratio of the same to the waste rubber / plastic pyrolysis oil being 100:15 according to the formula, polyester films are added above and below the sample respectively, and then the sample is placed ona vulcanizer or a mooney viscometer and heated for 10 minutes at 180 DEG C or 160 DEG C or 140 DEG C, and is taken out and placed for 5 minutes at room temperature, then the polyester films above andbelow the sample are uncovered and overlapped, and then moved to a fluorescent lamp for observing, and the characteristics of dyeing shallower than 101 C or 601 C belong to one, or a combination of more than one, of IV, V and VI, with IV being 180 DEG C, V being 160 DEG C, and VI being 140 DEG C.

Description

technical field [0001] The invention proposes a waste rubber / plastic pyrolysis oil used as a rubber / plastic softening agent or a viscosifier and its preparation method, which relates to product innovation through thermal cracking process of waste rubber / waste plastic; it belongs to waste rubber / waste plastic pyrolysis Method to extract oil or coupled with the technical scope of the business model. technical background [0002] The thermal cracking and oil extraction of waste rubber / waste plastics is becoming more and more popular in recent years. Although there are reports in the literature, the oil extracted can be used as fuel, as coal washing flotation agent to replace diesel oil, as Rubber softener, etc. [0003] However, the rubber / plastic pyrolysis oil obtained by pyrolysis always contains wax or / and colloid, etc. If this oil is used as fuel, it will emit black smoke and pollute the air, and it will make the engine piston easy to deposit carbon; If the oil is reused ...
