Abstract

The invention discloses an environment-friendly tire regenerated rubber softener. In order to overcome the deficiencies of toxic and harmful substances and pungent odor in the softener used in the existing tire reclaimed rubber, the present invention mixes cottonseed oil pitch 40 and soybean oil pitch 10 in the reaction vessel in sequence, and heats up to 80°C. , 60 revolutions per minute and vacuum stirring for 30 minutes, then add slick pitch 28, fennel oil 11, and tall oil 10 to the reaction kettle in turn, and vacuum stir for 30 minutes, and finally add rosin 1 to the reaction kettle, mix, and heat to 120°C. Stirred under vacuum for one hour to obtain the product. The invention is used as a softener for environment-friendly tire regenerated rubber. It is non-toxic, tasteless, environmentally friendly, has good plasticity, does not migrate and does not change color, has good softening effect, and can increase product gloss, viscosity, plasticity and tensile strength.

Description

technical field [0001] The invention relates to a tire regenerated rubber softener, in particular to an environment-friendly tire regenerated rubber softener. Background technique [0002] The softening agent used in existing tire reclaimed rubber is coal tar, aromatic hydrocarbon oil, pine tar, etc., and its disadvantage is that it contains toxic and harmful substances such as benzene, naphthalene, phenol, anthracene, pyridine alkyl aromatic hydrocarbons and asphalt, and has strong The pungent smell, harsh processing environment, affect work efficiency and product quality, poor environmental plasticity, migration and discoloration, poor softening effect, and unsatisfactory gloss, viscosity, plasticity and tensile strength of the product. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned deficiencies and provide a kind of environment-friendly tire regenerated rubber softener, which is non-toxic, tasteless, environment...
