Problems solved by technology

Although sisal fiber is a rigid fiber that can enhance the mechanical properties of wood-plastic composites, it is not conducive to the formation of good interfacial compatibility with polypropylene resin due to the large number of hydroxyl groups on the surface. Therefore, a certain amount of compatibilizer should be added to Improving Interfacial Compatibility Between Sisal Fibers and Polymer Groups

Abstract

The invention discloses a lubricant for a wood-plastic composite material and a preparation method of the lubricant. The lubricant is prepared from the following raw materials by weight: 10-20 g of 12-hydroxystearic acid, 5-10 g of pentaerythritol, 0.1-0.5 ml of dibutyltin dilaurate, 5-10 ml of toluene diisocynate, 50-100 ml of dimethylformamide and 100-150 ml of dimethylbenzene. The lubricant provided by the invention has the advantages of low cost, good chemical stability, low toxicity, excellent processability and the like. A sal hemp and polypropylene wood-plastic composite material modified by the lubricant provided by the invention can be widely applied to the industries and fields of automobile industry, construction industry, interior decoration, household appliances, transportation and the like.

Description

technical field [0001] The invention relates to a lubricant preparation technology, in particular to a lubricant for wood-plastic composite materials and a preparation method thereof. Background technique [0002] Because of its low price and excellent performance, wood-plastic composite materials are widely used in industries such as automobile industry, construction industry, interior decoration, home appliances and transportation. Combining the advantages of Guangxi sisal to develop sisal polypropylene wood-plastic composite materials is very beneficial for the in-depth development of Guangxi's agricultural product resources and the improvement of the added value of local products. Although sisal fiber is a rigid fiber that can enhance the mechanical properties of wood-plastic composites, it is not conducive to the formation of good interfacial compatibility with polypropylene resin due to the large number of hydroxyl groups on the surface. Therefore, a certain amount of ...
