Embodiment 1

[0011] The rubber tire softener is characterized in that it is prepared by the following process: adopting continuous acetone extraction and rapid distillation, according to the selectivity of acetone to different fractions, refining with acetone to extract tricyclic and polycyclic aromatic hydrocarbons, The remaining monocyclic bicyclic aromatic hydrocarbons and light components are softeners. After the acetone is preheated, it is pumped into the extraction tower from the top of the tower by a metering pump, and the feeding amount is controlled by the metering pump, while the raw material oil to be extracted is pumped into the extraction tower from the bottom of the tower. The acetone refining is to first measure the mutual solubility temperature of the oil to be tested and acetone at different agent-to-oil ratios, and then set the acetone extraction temperature according to the mutual solubility temperature for solvent refining. The determination method of described miscible...

Embodiment 2

[0013] The rubber tire softener is characterized in that it is prepared by the following process: adopting continuous N-methylpyrrolidone extraction and rapid distillation, according to the different selectivity of N-methylpyrrolidone to different fractions, through N-methylpyrrolidone Refining, extracting tricyclic and polycyclic aromatic hydrocarbons, remaining monocyclic bicyclic aromatic hydrocarbons and light components to obtain softener. The N-methylpyrrolidone is pumped into the extraction tower from the top of the tower by a metering pump after being preheated, the feeding amount is controlled by the metering pump, and the raw material oil to be extracted is pumped into the extraction tower from the bottom of the tower. The refining of N-methylpyrrolidone is to first measure the mutual solubility temperature of the oil to be tested and N-methylpyrrolidone at different agent-to-oil ratios, and then set the extraction temperature of N-methylpyrrolidone according to the m...

Abstract

The invention relates to a rubber tire softening agent. The technique is characterized by comprising the following steps: by adopting continuous solvent extraction and quick distillation, carrying out solvent refining to extract out tricyclic and polycyclic aromatic hydrocarbons, residual monocyclic and bicyclic aromatic hydrocarbons and light components according to different selectivities of solvent for different fractions, thereby obtaining the softening agent. The rubber tire softening agent belongs to an environment-friendly product. When the softening agent is used in the tire tread rubber, the rubber has the advantages of excellent aging resistance, excellent rolling resistance and favorable slippery resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber tire softener. Background technique [0002] Rubber softeners can be divided into petroleum-based, coal-tar-based, pine-tar-based, fatty oil-based filler oils and synthetic plasticizers according to their sources. Petroleum-based rubber softeners are mainly used in tire tread rubber, including aromatic oils, naphthenic oils, paraffinic oils, machine oils, heavy oils, asphalt oils, and petroleum resins. Traditional aromatic hydrocarbon oil is a rubber softener widely used in the rubber industry, but the content of polycyclic aromatic hydrocarbon compounds is relatively high. Aromatic oil is a commonly used rubber softener in rubber formulations, especially tire compound formulations. The hazards of aromatic oils to human health and environmental pollution have attracted great attention from various countries. Major tire companies have started to search for aromatic oils. ...
