Description
Technical field:
The present invention relates to a kind of method and resulting material of this method that utilizes straw to make wood plastic composite, the method and the resulting material of this method of the wood plastic composite that the residual film of straw that contains residual once visited place film that is reclaimed under the northern mulching film planting pattern of especially a kind of main utilization and waste or used plastics is made.
Background technology:
A large amount of stalks that agricultural production is at present produced, the one, chopping and returning as fertilizer sources, but the long-term use of this kind processing method can increase the possibility that crop pest takes place, and the value of its utilization is also lower; The 2nd, act as a fuel, the value of its utilization greatly reduces, and what also have then is as offal treatment, like burning disposal, has both caused the waste of resource, again contaminated environment.
Someone is used to make the conpressed fibers plate; And owing to technologic reason; As adding a large amount of adhesives, especially wherein contain a certain amount of formaldehyde, will form harm to human body and be used for building materials for civilan use; Moreover because its intensity of reasons is generally lower, purposes is restricted.
The somebody utilizes straw as paper making raw material; But at present a lot of agriculture producing region, especially dry area in north china use the mulching film planting pattern in a large number, and residual once visited place film also mixes in wherein in a large number when reclaiming stalk; For papermaking is fatal problem; It is separated very difficulty, almost be impossible according to present process, thereby make it can't be used for papermaking.
In the mulching film planting process, also produce simultaneously a large amount of residual films, reclaiming back one at present is that plastic processing enterprise utilizes as reclaimed materials again, but owing to the separation difficulty of a large amount of foreign material of unworthily occupying a place among them is difficult to utilize.
Meanwhile, also can produce a large amount of waste or used plastics in our daily life, its regeneration
Therefore a kind ofly can effectively utilize straw; Especially utilize utilizing method and utilizing the high-intensity ep-type material of this method manufacturing of the straw that contains residual once visited place film that reclaimed under the northern mulching film planting pattern, the ep-type material that especially can be applied to civil buildings just arises at the historic moment.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly can effectively utilize straw, especially utilize the straw that contains residual once visited place film that is reclaimed under the northern mulching film planting pattern to make the method for construction material and the composite architectural materials that utilizes this method to produce.
