A method of recycling waste plastics to prepare fillers

Abstract

The invention relates to a method for preparing a filler by recycling waste plastic. The method comprises: (1) weighing 9-20 parts of a modifier, 20-40 parts of plastic powder, 26-50 parts of an adhesive, 45-100 parts of stone powder, and 1-15 parts of wood powder; (2) carrying out stirring mixing on the modifier and the plastic powder, standing for 15-30 min, adding the adhesive, the stone powder and the wood powder, and continuously carrying out mixing stirring to obtain a mixture for spare; and (3) adjusting the pH value of the mixture with citric acid to 5.5-6.5 so as to obtain the filler. According to the present invention, the recycled waste plastic is adopted to process into the filler, the filler provides the good filling effect on the holes on the Eucalyptus wood plate surface, the Eucalyptus wood plate is slightly acidic, and the prepared filler and the Eucalyptus wood plate have the similar characteristic and are easily bonded so as to achieve the filling purpose; and the recycled plastic is adopted as the filler, such that the method is the process with characteristics of turning of waste into treasure and environmental protection, the filler production cost is reduced, and the problem that the plastic in the garbage is difficultly treated is solved.

Description

technical field [0001] The invention relates to a method for preparing fillers, in particular to a method for recycling waste plastics to prepare fillers. Background technique [0002] With the continuous development of society, more and more garbage is produced in cities, among which discarded plastic products account for more than 50% of the total garbage. Due to the slow degradation of polymer material products, poisonous and harmful gases will be produced by incineration, so discarded plastic products have become a difficult problem to deal with in garbage. [0003] Eucalyptus is one of the main plantation fast-growing tree species in my country. It takes 1 year to mature, 3 years to mature, and 5 years to harvest and utilize. Eucalyptus wood has been mainly used for the production of wood chips and pulp for a long time, and the production of eucalyptus hardboard and particleboard has a relatively long history. In recent years, a large number of fast-growing eucalyptus...

AI Technical Summary

Problems solved by technology

Because there are many holes in the surface layer of eucalyptus board, if it is directly used to make melamine board, the product quality will be poor and the material will be lost

The quality effect of the produced triamine board is not good, which makes the production efficiency of finished products extremely low

Gradually people began to use putty powder to fill the holes on the board surface, but the cost of putty powder is relatively high, and if some holes are too large, a large amount of putty powder will be used, which consumes materials and costs more
