Abstract
The invention relates to plastic wood taking garbage bags and pine sawdust as base materials, and a processing method of the plastic wood. The processing method comprises the steps of 1) preparing raw materials, and the like, wherein the raw materials of the plastic wood comprise the following components in parts by weight: 60-80 parts of plastic garbage bags, 90-100 parts of pine sawdust, 2-8 parts of coupling agent, 1-2 parts of lubricant, 10-15 parts of calcium carbonate, 1-1.5 parts of antioxygen and 10-15 parts of polyester fiber. Compared with the prior art, the plastic wood and the processing method have the beneficial effects that wastes are recycled; the plastic garbage bags and the pine sawdust are converted into serviceable materials; the plastic wood is long in service life and can be used repeatedly; the service time of the plastic wood is above 5 times longer than that of wood; and the manufacturing cost of the plastic wood is one second to one third of that of the pure wood.
Description
Technical field
The present invention relates to a kind of plastic-wood material technical field, especially belong to a kind of and make the plastic-wood material technical field based on kitchen-can bag and the remaining pine sawdust of manufacturing rosin.
Background technology
Moulding wood is a kind of material of construction of very environmental protection, can successfully waste and old resource be utilized again.Plastic-wood floor has also become building materials industry to develop the waterproof and dampproof high environmental protection of new direction, plastic wood sheet, combine the plurality of advantages of vegetable fibre and plastics macromolecular material, can substitute timber in a large number, can effectively alleviate China's Forest Resources poorness, wood supply contradiction in short supply, be a kind of low-carbon (LC), green, renewable ecological plastic-wood material capable of circulation that has development prospect.
Kitchen-can bag, it is white pollution, it is the environmental pollution that global urban all has, can both see a large amount of depleted plastics everywhere in various public places, they come from nature, make by the mankind, but be difficult for when finally ascribing the Nature to being dissolved, thereby influenced the ecotope of the Nature by nature.From the angle that economizes on resources because the plastics main source is to face exhausted petroleum resources, should reclaim as far as possible, but since present stage the production cost that reclaims again far above direct production cost, under existing condition of market economy, be difficult to accomplish.
Pine sawdust is the residual waste behind the processing rosin, generally all adopts the processing that abandons or fill up.How with kitchen-can bag and pine sawdust after the proportioning combination of science, in addition routine is moulded wooden processing and manufacturing technology again, can become a kind of novel plastic-wood material.
Summary of the invention
The present invention has solved the problems referred to above just, provides a kind of and moulds wooden material based on kitchen-can bag and the remaining pine sawdust manufacturing of manufacturing rosin.
The present invention is by realizing to foretell technical scheme.
A kind of with refuse bag, pine sawdust be base-material mould wood and working method thereof, step of the present invention is,
