The invention discloses a new kind of environment-friendly plant softener cottonseed oil regenerated from waste rubber, which is brown viscous liquid. It is detected by infrared spectroscopy, nuclear magnetic resonance spectroscopy and gas phase mass spectrometry. The main components are linoleic acid 51.3%, palmitic acid 23.2%, oleic acid 19.1%, stearic acid 2.8%, and cotton phenol 1.2%. The analysis of thermal weight loss shows the main components. For the unsaturated acid with large molecular weight, the boiling point is above 240 C. The invention has the following advantages: the cottonseed residuum does not contain the carcinogenic polycyclic aromatic hydrocarbons, which conforms to the EU REACH regulation; its regenerated rubber as a softener can greatly retain the mechanical and high elastic properties of the waste rubber; it can quickly soften the waste rubber powder and get the regenerated adhesive suitable for the Mooney viscosity; the cottonseed residuum is softened as softening. The regenerated adhesive has excellent aging resistance, and the 2.8% stearic acid can form synergistic effect with the reactivator 510, and the cottonseed residue composite softener overcomes the disadvantages of high Mooney viscosity and big rebound.

一种用于废旧橡胶再生的环保植物软化剂棉籽渣油
本专利技术涉及一种用于废旧橡胶再生的环保植物软化剂棉籽渣油,属于再生橡胶
技术介绍
利用废轮胎等橡胶制品生产再生橡胶,目前再生胶企业大多采用动态脱硫罐在高温(200至300℃)下脱硫,在脱硫工艺过程中产生了大量有毒的废气和废水,这些废气主要来自于污染严重的煤焦油等软化剂,影响身体健康,特别是影响企业操作工人的身体健康,严重时还有可能引发癌症。有一些大型再生胶企业投入了大量资金治理废气和废水,环保虽然达标,但仍有少量臭气。现有再生助剂体系中,软化剂用量占有很重的比例。市场上通用的常用软化剂有煤焦油和石油抽出物等,尽管其软化效果好,生产的再生胶门尼粘度适中,拉伸强度和扯断伸长率较高。但因其粘度大(需加热处理),不易称量与输送。且其成分复杂,气味大,是污染的主要来源。目前大多数再生胶企业已经不再使用。大豆油、环烷油和地沟油等,表现为粘度小,无需加热即可称量和输送,软化效果较好,但是其作为软化剂的再生胶拉伸强度较低,扯断伸长率损失较大。松焦油和妥尔油都来源于植物残渣,无污染,它们作为软化剂的再生胶拉伸强度和扯断伸长率 ...
