Abstract
The invention relates to a preparation method of environmentally friendly rubber softening agent, including the following steps: (1) 40-50 parts of white oil is fed into a closed end kettle by a pump, 25-35 parts of wax melted by heating is fed into the same kettle, the temperature in the kettle is controlled to be 25-35 DEG C at the moment, and uninterrupted stirring is carried out for 60-90 minutes, so that the white oil and the wax are mutually dissolved into wax oil; (2) 20-30 parts of liquid chlorine is fed into the closed end kettle filled with the wax oil, the temperature in the kettleis controlled to be 55-80 DEG C, stirring is carried out for 3-4 hours, the temperature is reduced to 35-55 DEG C, 4-6 parts of stabilizing agent diethylene glycol diglyciol ester is added, and stirring is carried out for 60-90 minutes, thus obtaining the environmentally friendly rubber softening agent. The invention adopts totally closed technology, and rubber softening agent with the content ofpolyaromatic hydrocarbon more than 50% is reduced to the rubber softening agent with benzo (a) pyrene (BaP) less than 1mg/kg and total content of eight PAHs less than 10mg/kg in polyaromatic hydrocarbon, thus causing the product to completely meet the technical standard of EU PAHs requirement.
Description
Technical field
The present invention relates to a kind of preparation method of Rubber Softener.
Background technology
Present existing Rubber Softener is a kind of aromatic hydrocarbons base class high product that contains, the highest aromatic hydrocarbons amount can reach more than 50%, the too high harmful HUMAN HEALTH of aromaticity content, wherein 8 kinds of (PAHs) elements exceed standard and can make the people carcinogenic, so EU Committee has issued 2005/69/EC " about the instruction of restriction polycyclic aromatic hydrocarbons (PAHs) " in 2005, also claim European Union green rules.
Summary of the invention
Technical problem to be solved by this invention provides a kind of environmental requirement that reaches, and useful human health meets the preparation method of environment-friendly rubber softening agent of standard-required of " PAHs " of EU Committee issue.
The present invention adopts technical scheme:
The present invention adopts following components by weight portion: white oil 40-50 part, paraffin 25-35 part, liquid chlorine 20-30 part, stablizer ethylene glycol diglycidylether 4-6 part; Employing is prepared as follows method steps: remain silent white oil in the reactor with the pump input earlier (1), the paraffin that to heat again after melting is imported in the same reactor, the interior temperature of reactor this moment is controlled between 25-35 ℃, uninterruptedly stirred 60-90 minute, white oil and paraffin are dissolved into paraffin oil mutually; (2) liquid chlorine is equipped with in the reactor of remaining silent of paraffin oil by the input of chlorine vaporizer, reactor temperature is controlled at 55-80 ℃, stir after 3-4 hour, temperature is reduced to add the stablizer ethylene glycol diglycidylether between 35-55 ℃ and stir and promptly to make after 60-90 minute.
Beneficial effect of the present invention:
EU Committee has developed and published the technological standard and the requirement of the green rules of 2005/69/EC " about the instruction of restriction polycyclic aromatic hydrocarbons (PAHs) " abbreviation European Union in order to protect EU member country's human health and environmental safety; for technological standard and the requirement of satisfying PAHs; the present invention adopts Totally closed production technology; with the polycyclic aromatic hydrocarbons amount is that 50% above Rubber Softener is reduced to benzo in the polycyclic aromatic hydrocarbons (a) pyrene (BaP) and is lower than 1mg/kg; 8 kinds of PAHs total contents are lower than the following Rubber Softener of 10mg/kg, thereby make product reach the technological standard requirement of the PAHs of European Union fully.
Product of the present invention is called for short the green rules of European Union through EU Committee's " about instruction of restriction polycyclic aromatic hydrocarbons (PAHs) ", and China detects general headquarters and detects conformance with standard, and benzo (a) pyrene (BaP) is lower than 1mg/kg, 8 kinds of PAHs total contents are lower than 10mg/kg.It is as shown in the table for examining report:
