Embodiment 1

[0094] according to figure 1 Process, with 50 parts by weight of major ingredient natural vegetable oil (10 parts by weight of camellia oil, 15 parts by weight of cottonseed oil, 15 parts by weight of linseed oil, 10 parts by weight of palm oil), auxiliary material biochemical oil (comprising stalks biochemical oil and shell biochemical oil (10 parts by weight of coconut shell, 10 parts by weight of pine nut shell, 5 parts by weight of peanut shell>) 50 parts by weight, after mixing and stirring, add 11.42 parts by weight of a phthalate ester catalyst were used to catalyze and synthesize a softener; the softener index is shown in Table 1 below. When in use, the whole (outer) tire rubber powder is recovered for every 1000 parts by weight. The fineness of the rubber powder is 20 meshes. 20 parts by weight, heated and stirred evenly; using high-temperature dynamic desulfurization (temperature 200 degrees Celsius, pressure 2.2Mpa, desulfurization time 80 minutes) process, the tech...

Embodiment 2

[0096] Main ingredient natural vegetable oil (10 parts by weight of tea oil, 30 parts by weight of cottonseed oil, 30 parts by weight of flax oil) 70 parts by weight, auxiliary material biochemical oil (comprising 5 parts by weight of straw and shell biochemical oil ) 35 parts by weight, after mixing and stirring, add 12 parts by weight of phthalate catalyst, Carry out catalytic synthesis softening agent; The softening agent index is as shown in table 1 below. When in use, recover the whole (outer) tire rubber powder per 1000 parts by weight. The fineness of the rubber powder is 30 meshes. 25 parts by weight, heated and stirred evenly; high-temperature dynamic desulfurization (temperature 200 degrees Celsius, pressure 2.2Mpa, desulfurization time 70 minutes) process, the technical indicators of the reclaimed rubber thus obtained are: moisture10Mpa, elongation at break>390%, Mooney viscosity<70ML. Exceeding the national tire reclaimed rubber premium product level.

Embodiment 3

[0098] 70 parts by weight of natural vegetable oil (40 parts by weight of cottonseed oil and 30 parts by weight of palm oil), auxiliary materials biochemical oil (including straw and shell biochemical oil ) 25 parts by weight, after mixing and stirring evenly, 10.85 parts by weight of phthalate catalyst is added to catalyze the synthesis of softening agent; the softening agent index is shown in Table 1. When in use, the whole (outer) tire rubber powder is recovered for every 1000 parts by weight. The fineness of the rubber powder is 30 meshes. 30 parts by weight, heated and stirred evenly; adopt high-temperature dynamic desulfurization (temperature 210 degrees Celsius, pressure 2.5Mpa, desulfurization time 75 minutes) process, the technical indicators of the reclaimed rubber thus obtained are: moisture content 10.5Mpa, elongation at break>400%, Mooney viscosity<68ML. Exceeding the national tire reclaimed rubber premium product level.

Abstract

The invention provides a reclaimed rubber softening agent. The reclaimed rubber softening agent is obtained by reacting a softening agent main material with a softening agent auxiliary in the presence of a catalyst; the softening agent main material comprises a natural vegetable oil ingredient, while the softening agent auxiliary comprises a natural biochemical oil ingredient, and the catalyst is a phthalate; the natural vegetable oil ingredient is a natural vegetable oil and / or natural vegetable oil foots; the natural biochemical oil ingredient is a natural biochemical oil and / or natural biochemical oil foots. The reclaimed rubber softening agent is a composite product prepared by compounding the natural vegetable oil and the biochemical oil and refining the mixed oil under the catalytic action of phthalate. The softening agent passes the PONY test of the international authoritative detection mechanism, meets the requirements of the European Union REACH environmental protection laws and regulations and passes the authentication of China Quality Certification.

Description

technical field [0001] The invention relates to the field of reclaimed rubber, in particular to a reclaimed rubber softener and a preparation method thereof, more specifically to an EU environment-friendly reclaimed rubber softener and a preparation method thereof. Background technique [0002] According to the figures released by the National Development and Reform Commission in the "Annual Report on China's Comprehensive Utilization of Resources (2014)", in 2013 my country produced 10.8 million tons of waste tires, surpassing the United States and becoming the world's largest producer of waste tires. This does not include a large number of waste rubber products such as rubber hoses, tapes, rubber sheets, motorcycle tires, electric tires, bicycle tires, rubber shoes, etc., which are scrapped every year, and the amount is also several million tons. The amount of waste rubber produced in my country every year is conservatively estimated at more than 15 million tons. With the...
