Abstract
The invention discloses a waste plastic building template, and by weight ratio, the building template comprises 13%-17% waste polyvinyl chloride particles with diameters of 2-3 mm, 18%-22% waste high-density polyethylene particles, 18%-22% line-shaped low-density polyethylene particles, 8%-12% low-density polyethylene particles, and 33%-37% polyvinyl chloride particles.
Description
Technical field
The present invention relates to building material technical field, especially a kind of waste or used plastics construction formwork and manufacture method thereof.
Background technology
At present, construction formwork is generally to adopt timber, bamboo and structural metal etc. to make.For the construction formwork that adopts plastics to make, be generally to utilize brand-new plastic grain production, its production prices are expensive.And, for this construction formwork that is made of plastics, due to the sex change of plastics, generally cannot recycle after use, thereby produce a large amount of pollutions.In addition, because the product hardness of new plastic particle is inadequate, therefore, the construction formwork that produces is also yielding.
Summary of the invention
In view of this, the invention provides a kind of waste or used plastics construction formwork and manufacture method thereof, and the problem that will cause a large amount of pollutions higher, yielding in order to the price that solves the construction formwork that plastics of the prior art make.
According to an aspect of the present invention, a kind of waste or used plastics construction formwork is provided, by weight percentage, the component of this construction formwork comprises: particle diameter is the waste polyvinyl chloride particle 13%～17% of 2-3 millimeter, waste and old high density polyethylene (HDPE) particle 18%～22%, linear low density of polyethylene particle 18%～22%, low density polyethylene (LDPE) particle 8%～12%, and polyvinyl chloride particles 33%～37%.
Preferably, by weight percentage, the component of this construction formwork comprises: waste polyvinyl chloride particle 15%, waste and old high density polyethylene (HDPE) particle 20%, linear low density of polyethylene particle 20%, low density polyethylene (LDPE) particle 10%, and polyvinyl chloride particles 35%.
Preferably, various said components merge by the composite gridding material.
Preferably, above-mentioned composite gridding material is glass fiber.
According to another aspect of the present invention, a kind of manufacture method of above-mentioned waste or used plastics construction formwork is provided, comprise: waste polyvinyl chloride, waste and old high density polyethylene (HDPE), linear low density of polyethylene, low density polyethylene (LDPE) and polyvinyl chloride are pulverized and are the fritter of 2-3 millimeter, and mix; The material that mixes is heated to 260-300 degree centigrade, clamp-ons to mould, and be covered with composite gridding material, then roller-compaction; Template in low temperature wind after moulding is cooling.
Preferably, carrying out before waste polyvinyl chloride, waste and old high density polyethylene (HDPE), linear low density of polyethylene, low density polyethylene (LDPE) and polyvinyl chloride mix after pulverizing, described method also comprises: the material after pulverizing cleans, and then dries.
Preferably, the material after heating is clamp-oned to mould comprised: use the material after twin-screw machine will heat to be squeezed in described mould.
Plastic building template provided by the invention adopts waste and old plastics to make, timber and the steel of flood tide have directly been saved, thereby saved cost of production, and, because waste and old plastics are not yielding, therefore, its construction formwork of making is not yielding yet, in addition, makes because this construction formwork adopts waste and old plastics, thereby can be recycling, reduced environment pollution.
Description of drawings
Fig. 1 is the process chart according to the manufacture method of the waste or used plastics construction formwork of the embodiment of the present invention one;
Fig. 2 is the test result according to the waste or used plastics construction formwork of the embodiment of the present invention.
The specific embodiment
Embodiment one
Fig. 1 is the process chart according to the manufacture method of the waste or used plastics construction formwork of the embodiment of the present invention, and as shown in Figure 1, the waste or used plastics construction formwork of the embodiment of the present invention can be by following technique manufacturing:
If necessary, can the various plastics after pulverizing be cleaned, standby after dry.
Step 4 is sent into these materials and is carried out mixing at a high speed in the machine of appointment on production line;
Step 6 is sent to the materials'use twin-screw machine after heating in the mould of appointment;
Step 7, overlay film covers the composite gridding material in mould;
Step 8 is carried out extrusion modling to material in mould;
Step 9 is carried out sub-cooled with the material of extrusion modling;
Step 11, at last with the finished product of well cutting according to certain specification packaging and warehousing.
Fig. 2 is the test result of the waste or used plastics construction formwork of the embodiment of the present invention.
Embodiment two
In the present embodiment, technological process is similar to embodiment, and difference is, after pulverizing, each compositions in weight percentage: PP (13%), HDPE (22%), LLDPE (22%), LDPE (8%), PVC (33%) prepare burden; Enter again production line and be heated to 260 degrees centigrade after these materials are carried out mixed at high speed; In addition, in the present embodiment, at overlay film, glass fiber is covered in mould.
Embodiment three
In the present embodiment, technological process is similar to embodiment, and difference is, after pulverizing, each compositions in weight percentage: PP (17%), HDPE (18%), LLDPE (18%), LDPE (12%), PVC (37%) prepare burden; Enter again production line and be heated to 280 degrees centigrade after these materials are carried out mixed at high speed; In addition, in the present embodiment, at overlay film, glass fiber is covered in mould.
As mentioned above, plastic building template of the present invention adopts waste and old plastics to make, saved cost of production, and, because waste and old plastics are not yielding, therefore, its construction formwork of making is not yielding yet, in addition, makes because this construction formwork adopts waste and old plastics, thereby can be recycling, reduced environment pollution.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of claim of the present invention and equivalent technologies thereof, the present invention also is intended to comprise these changes and modification interior.
