Abstract
A composite square material used in building operations comprises a plastic outer shell and a multi-layer bearing body. The composite square material is characterized in that the multi-layer bearing body is filled in the plastic outer shell and the plastic outer shell and multi-layer bearing body are both integral structures through one-step molding. The preparation method of the square material comprises the following steps: mixing 70-90% of waste plastic and 10-30% of wood fibre or bamboo fiber, placing the mixture in a container to heat to 210-180 DEG C and melt the mixture and preparing plastic strips; preparing the multi-layer bearing body by processing the waste wood products and bamboo to strips and then binding the strips to form an integral structure according to the set length, width and thickness; separately placing two plastic strips and the multi-layer bearing body in a trough section shaper and pressing to form the product with a hydraulic machine under the pressure of 20-50KN, wherein the multi-layer bearing body is arranged between the two plastic strips. The composite square material of the invention has low production cost, easy preparation, convenient construction and use, lower construction cost, good economic efficiency and significantly social efficiency.
Description
(1) technical field:
The present invention relates to a kind of building materials, particularly a kind of compound square bar of processing by waste plastics.
(2) background technology:
Along with Chinese economic development, urban construction is more and more flourishing, and the building of various patterns is rised sheer from level ground, and like rain the back spring bamboo, has beautified our living space.At present, because timber is in light weight, is prone to saw and digs, it is convenient to construct, the general user's carpentery workshop of building engineering construction template keel and decorative engineering back cord material.But a large amount of harvest of forest trees must aggravate natural environment deterioration, and China's forest reserves per capita has only 20% of world's per capita share.The forest reserves lack, and cutting is greater than output.This is a kind of disaster to the China that the forest reserves lack really, because China is Shaolin country, so the protection forest resourceies, development forest substitute is the construction industry development inexorable trend.In addition, the lumps of wood receives wind and scrapes the Exposure to Sunlight meeting and the strain cracking phenomenon occurs, influences the shaping structures quality.
(3) summary of the invention:
It is simple that the technical problem that the present invention will solve provides a kind of production technology, the compound square bar that uses in a kind of building operations that waste or used plastics capable of using, woodwork or bamboo product leftover pieces are processed.
The technical scheme that adopts is:
The compound square bar that uses in a kind of building operations comprises polymer shell body and multilayer supporting mass, and its main points are that the multilayer supporting mass is filled in the polymer shell body, and polymer shell body and multilayer supporting mass are one-time formed overall structure.
The manufacturing approach of the compound square bar that uses in a kind of building operations is:
1,,, dries that to remove moisture content subsequent use like PEF polybag and polypropylene plastic bottle etc. with the waste or used plastics goods that reclaim; With waste and old wood, mao bamboon or bamboo product processing growth 20mm, the wood fibre of diameter 2-0.5mm is subsequent use;
2, the wood fibre of above-mentioned two kinds of raw materials with the waste plastics of 70-90%, 10-30% mixed, after putting into container and being heated to 210 ℃ of-180 ℃ of fusings, process the rectangular sheet of polymer, temperature is controlled at 150 ℃-120 ℃.Above-mentioned percentage is weight percentage.
3, the multilayer supporting mass is that waste and old woodwork or bamboo are processed strip respectively, is bonded to an overall structure by preseting length, width and thickness again.
4, two polymer strip sheets and multilayer supporting mass are placed respectively in the rectangle and trapezium channel section shaper, and the multilayer supporting mass is folded in the middle of two polymer strip sheets, compresses moulding at the 20KN-50KN hydraulic press by pressure.Force cooling with cold water in the forming process, can accomplish the one-shot forming process in 10 minutes.
Polymer shell body primary raw material of the present invention is that waste plastics is food waste bag, woven bag, plastic toy, instant noodles plastic casing etc., helps beautifying the environment, and eliminates white pollution.The food-packaging bag that abandons at present, instant noodle box etc., because can not cracking, being seen everywhere, people are referred to as white pollution, have become headachy public hazards.Discarded food bag is reclaimed, process the plastic building flitch, can turn waste into wealth, benefit the nation and the people.
Multilayer of the present invention supporting obturator is to adopt waste and old bamboo or used timber leftover pieces, the growth cycle of bamboo will be far away faster than the growth cycle of trees, so, can save a large amount of timber, help forest conservation.
The present invention has simple and compact for structure, and low cost of manufacture, making easily are convenient to construction and are used, and reduce building costs, good economic benefit is not only arranged, and have remarkable social benefit.
(4) description of drawings:
Fig. 1 is an embodiment of the present invention structural representation.
Fig. 2 is a sectional structure sketch map of the present invention.
(5) specific embodiment:
The compound square bar that uses in a kind of building operations comprises polymer shell body 1 and multilayer supporting mass 2, and multilayer supporting mass 2 is fixedly installed in the polymer shell body 1, and polymer shell body 1 is one-time formed overall structure with multilayer supporting mass 2.
The compound square bar manufacturing approach of using in a kind of building operations is:
Waste or used plastics goods with reclaiming dry and remove moisture content.Then, with waste and old woodwork processing growth 20mm, the wood fibre of diameter 1mm.Above-mentioned two kinds of raw materials are mixed (above-mentioned percentage is weight percentage) by 80% waste plastics, 20% wood fibre, put into container be heated to 180 ℃ dissolve after, process the rectangular sheet of polymer, temperature is controlled at 130 ℃.A plurality of waste and old veneers are processed strip respectively, and the cementation connection successively respectively of a plurality of waste and old veneer.Above-mentioned two polymer strip sheets that are prepared into and multilayer supporting mass are placed respectively in the rectangle and trapezium channel section shaper, and the multilayer supporting mass is folded in the middle of two polymer strip sheets, compresses moulding at the 20KN-50KN hydraulic press by pressure.Force cooling with cold water in the forming process, can accomplish the one-shot forming process in 10 minutes.
