Abstract
The invention provides a proportion of raw materials used for producing dedicated plastic templates in construction. The plastic templates comprise the following raw materials in parts by weight: 40-50 parts of PPR reworked material, 15-25 parts of PE reworked material, 20-30 parts of PP reworked material, 1-2 parts of paraffin wax, 2-3 parts of stearic acid, 4-5 parts of coupling agent and 1-2 parts of brightener. The invention has the advantages that the dedicated templates in construction manufactured according to the above raw material proportion and production process are used widely, can be used in construction engineering, such as industrial construction, civil construction, roads, bridges, culverts, tunnels, underground engineering and the like, and the inventory turns of usage is far higher than that of plywood and bamboo panel; the weight is light and the price is low; the invention is recycled and has no toxity, no taste and no pollution, thus belonging to the category of recycling economy and environment-friendly products advocated by the country; and the performance index, such as 14.3MPa of tensile strength, 10.5MPa of impact strength, 24KJ/m<2> of bending strength and the combustion performance all meet standard requirements.
Description
Technical field
The present invention is the raw materials used proportioning of a kind of production dedicated plastic templates in construction.
Background technology
Along with the develop rapidly of Building Trade in China, housing-group miscellaneous is rised sheer from level ground like the mushrooms after rain throughout the country, and the development of construction industry has also directly brought the increase to conventional template timber, wooden form, glued board, bamboo offset plate demand.This is populous for one, and the country that the forest reserves are deficient relatively makes the matter worse.At present, employed glued board, bamboo offset plate all adopt the tackiness agent that contains formaldehyde, and the producer of the glued board of producing this type of in all parts of the country is thousands of, produce poisonous glued board every day and we can say and be difficult to describe with astronomical figure.
Because building form does not belong to the building structure product, it is " circulation material ", " replacement appliances ", " consumable products " in the construction work, so country and relevant department do not attach great importance to the negative effect after building template uses in whole use, a large amount of building template refuse pollutions urban environment, its poisonous element pollution know clearly the earth, air, and river, river, lake, sea have been polluted with rainwash, the knowledgeable people is being perplexed in the development of substitute products for many years always, is expected by people with the environmentfriendly products of moulding wooden reusable edible of generation.
Summary of the invention
The objective of the invention is to, solve above-mentioned existing existing problem, provide a kind of, utilize a kind of production dedicated plastic templates in construction raw materials used proportioning of reprocessed plastic(s) for main raw material to mould wooden reusable edible of generation.
The present invention is achieved in that proportioning by weight,
Three type polypropylene (PPR) reworked material 40-50, polyethylene (PE) reworked material 15-25, polypropylene (PP) reworked material 20-30, paraffin 1-2, stearic acid 2-3, even stick 4-5, light agent 1-2; 5 millimeters to 1.5 millimeters of three type polypropylene (PPR) reworked material 40-50, polyethylene (PE) reworked material 15-25, polypropylene (PP) reworked material 20-30 particle diameters.
Advantage of the present invention is, press the building dedicated templates that the above-mentioned raw materials proportioning is made, use extensively, can be used for construction work, as Industrial buildings, covil construction, highway, bridge, culvert, tunnel, underground works etc., the number of turnover of use is higher than glued board, bamboo offset plate far away, and is in light weight, price is low, because recycle is nontoxic, tasteless, pollution-free, belongs to country and advocate back recycling economy, environmentfriendly products category.Its performance index such as tensile strength 14.3Mpa, shock strength 10.5Mpa, flexural strength 24KJ/m
2, the equal conformance with standard requirement of combustionproperty, see Detailed Inspection report.
Embodiment
Below in conjunction with example in detail
1, the processing request of raw material:
PPR reworked material, PE reworked material, the above three kinds of ingredient requirements cleaning of PP reworked material impurity remove institute's containing metal and sieve through the pulverizer fragmentation, and particle diameter is controlled in 5 millimeters to 1.5 millimeters.
More than three kinds of reworked material water content must not surpass 2%.
2, the source requirement of raw material
Cold water pipe, hot-water line, PPR sheet material, the profiled material of PPR to reclaim.Bucket class, the food product pack class of PE to reclaim.PP is based on household electrical appliance plastics such as laundry inner bag, refrigerator linings.
Paraffin, stearic acid, even stick, light agent are the plastics additive, do not have other particular requirement.
3, raw material mixing requirement
Raw materials used PPR reworked material 40-50, PE reworked material 15-25, PP reworked material 20-30, paraffin 1-2, stearic acid 2-3, even stick 4-5, light agent 1-2;
A, example 1 as raw materials used 100 kilograms, are got 40 kilograms of PPR reworked materials, 20 kilograms of PE reworked materials, 30 kilograms of PP reworked materials, 1 kilogram in paraffin, 2 kilograms of stearic acid, 5 kilograms of even sticks, 2 kilograms of light agent;
B, example 2 as raw materials used 100 kilograms, are got 50 kilograms of PPR reworked materials, 15 kilograms of PE reworked materials, 25 kilograms of PP reworked materials, 2 kilograms in paraffin, 3 kilograms of stearic acid, 4 kilograms of even sticks, 1 kilogram of light agent;
4, making processes
A, all raw materials carry out weight proportion by above requirement, and per 100 kilograms of confected materials are put into stirrer and stirred; Churning time is no less than 3 minutes.
B, the raw material that stirs is put into single multiple screw extruder (molding machine that is produced from Jinhu County, 120 types above specification Shanghai, produce in Shuande, Qingdao, produce the Zhangjiagang, Jiangsu all can) produce.Require the screw rod warm area to be provided with rationally, can divide six districts progressively to heat up from opening for feed to mould.About one district's temperature is controlled at that 110 degree, two districts 120 degree, three districts, 135 degree, four districts, 150 degree, five districts 180 are spent, six districts 185 spend, positive and negative must not spending above three.
Through mould extrusion moulding → three rods press polish → conveying cooling → electric saw cutting → cleaning packing.
More than five proportioning production whole processes that step is the building plastic dedicated templates.
