Abstract

The invention discloses a preparation method of plastic cement for the transport roller of a willow twig peeling machine. The preparation method comprises following steps: (1) mixing polyether glycol,polyether triol, and liquefied diphenyl methane diisocyanate, heating the mixture to a temperature of 80-85 DEG C, carrying out reactions for 2-3 hours, cooling to a temperature of 60-65 DEG C, adding 17 to 22 parts by weight of PB-403 water soluble high brightness casein, maintaining the temperature, and keeping on stirring for 40-50 minutes to obtain a polymer solution; and (2) sequentially adding hexamethylene diisocyanate trimer, a chain extender HER, isopropoxyboronic acid pinacol ester, lithionite powder, aluminum silicate fiber cotton, and 1 to 2 parts by weight of dispersant into 40 to 45 parts by weight of polymer solution, continuously stirring for 100-120 minutes, carrying out vacuum degassing, pouring the mixture into a die, and curing the mixture to obtain a finished product.The provided preparation method has the advantages that the generated waste gas, waste solids, and waste water are little, and the preparation method is green and environmentally friendly. The prepared plastic cement has excellent mechanical properties, stable chemical properties, and a strong grasping force on willow twigs. Moreover, the surface energy of the plastic cement is low, and thus theplastic cement is not easily dyed by willow twigs.

Description

technical field [0001] The invention belongs to the technical field of wicker treatment, and in particular relates to a method for preparing plastic used for conveying rollers of a wicker peeling machine. Background technique [0002] Willow weaving is one of the traditional folk handicrafts in China. In recent years, with the development of economy, the industry of willow weaving has developed rapidly, and the consumption of willow is gradually increasing. The wicker processing technology first needs to peel off its outer skin, but manual peeling is labor-intensive, time-consuming and time-consuming, and the wicker peeling machine can solve this problem very well. The wicker peeling equipment is mainly composed of feeding trough, conveying device, It is composed of peeling device, guiding mechanism and power transmission mechanism. The main part of the conveying device is the conveying roller, whose function is to grab wicker and provide power for it, so that it can overcom...
