Abstract
Two-in-one full wood-plastic composite building formwork, it relates to building template technical field, and the upper and lower surface of PVC foam layer is provided with PVC not foaming layer；Its manufacture method is: step one: PVC powder, calcium powder, lignin, auxiliary agent through high speed mixer and be warming up to 120 DEG C then through low speed batch mixer be cooled to 55 DEG C enter twin screw 80 extrusion equipment main frames realize foaming；Step 2: PVC powder does not foam through twin screw 65 extrusion equipment main frame；Step 3: step one is entered allotter with the PVC powder of foaming in step 2 with the PVC powder not foamed and mixes；Step 4: the powder mixed in step 3 is extruded through mould；Step 5: the template extruded in step 4 is adopted shaping platform cooling molding temperature less than 10 DEG C；Step 6: the template shaped in step 5 is carried out cutting finished product, and is packed, warehouse-in；Its maintenance cost is extremely low, and bonding strength is higher, and intensity is better, non-friable；And it is substantially reduced cost.
Description
Technical field:
The present invention relates to building template technical field, be specifically related to a kind of two-in-one full wood-plastic composite building formwork.
Background technology:
The existing building template of existing market is based on plank sheathing, and wooden template is applied the earliest, owing to consume a large amount of timber, and dismounting template easily cleaves, the proportion of goods damageds are higher, and the general number of turnover is at 4-6 time, and substitute products more should be sought by the China not enriched for the forest reserves.Steel template: this template is the succedaneum of wooden template, product is with standardization and defines series.Its advantage is to save a large amount of timber, and can repeatedly use, and turnover utilization rate is up to 40 times, but it also has shortcomings:
1., cost high, average price, at 280 yuan/square metre, far exceeds the price of Wood-plastic formwork；
2., heavy, lifting inconvenience in construction, dismounting difficulty；
3., being limited by weight, single form area is little, uses middle splicing block number more, time-consuming, effort；
4., steel form and cement have certain affinity, during dismounting template, the cement products surface such as easy column or crossbeam produces butcher cuts, affects quality；
5., the easy corrosion of steel form.
The intensity of existing PVC foam plate is not suitable for building site and uses, and when the demoulding, edges of boards are frangible.And relatively costly, product requirement is significantly high.
Summary of the invention:
It is an object of the invention to provide a kind of two-in-one full wood-plastic composite building formwork, its maintenance cost is extremely low, and bonding strength is higher, and intensity is better, non-friable；And it is substantially reduced cost.
In order to solve the problem existing for background technology, the present invention adopts the following technical scheme that it comprises PVC not foaming layer, PVC foam layer, and the upper and lower surface of PVC foam layer is provided with PVC not foaming layer.
Its manufacture method is: the PVC powder of step one: 60KG, 40KG calcium powder, 20KG lignin, 20KG auxiliary agent are through the high speed mixer speed with 3000r/min and be warming up to 120 DEG C and be cooled to 55 DEG C then through low speed batch mixer and enter twin screw 80 extrusion equipment main frames and realize foaming；
Step 2: PVC powder does not foam through twin screw 65 extrusion equipment main frame；
Step 3: step one is entered allotter with the PVC powder of foaming in step 2 with the PVC powder not foamed and mixes；
Step 4: the powder mixed in step 3 is extruded through mould；
Step 5: the template extruded in step 4 is adopted shaping platform cooling molding temperature less than 10 DEG C；
Step 6: the template shaped in step 5 is carried out cutting finished product, and is packed, warehouse-in.
There is advantages that
(1), material source extensive, be worth cheap；
(2), wood-plastic products behave carefully and neatly done body synthetic products, according to requirements can adjust Product Process and formula at random, thus producing the material of different performance and shape, its section bar utilization rate is close to 100%；
(3), the wood of Wood-plastic material/mould base material and the equal Environmental Safety of usual auxiliaries thereof, nontoxic, without having side effects in its process of manufacture, therefore human body and environment are not all constituted any harm；
(4), maintenance cost extremely low, and life of product is several times as much as common natural timber；
(5), the scrap products of Wood-plastic material and reclaim waste product all can 100% regeneration, and without influence on product serviceability.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention adopts the following technical scheme that it comprises PVC not foaming layer 1, PVC foam layer 2, and the upper and lower surface of PVC foam layer 2 is provided with PVC not foaming layer 1.
Its manufacture method is: the PVC powder of step one: 60KG, 40KG calcium powder, 20KG lignin, 20KG auxiliary agent are through the high speed mixer speed with 3000r/min and be warming up to 120 DEG C and be cooled to 55 DEG C then through low speed batch mixer and enter twin screw 80 extrusion equipment main frames and realize foaming；
Step 2: PVC powder does not foam through twin screw 65 extrusion equipment main frame；
Step 3: step one is entered allotter with the PVC powder of foaming in step 2 with the PVC powder not foamed and mixes；
Step 4: the powder mixed in step 3 is extruded through mould；
Step 5: the template extruded in step 4 is adopted shaping platform cooling molding temperature less than 10 DEG C；
Step 6: the template shaped in step 5 is carried out cutting finished product, and is packed, warehouse-in.
This detailed description of the invention has the advantages that
(1), material source extensive, be worth cheap；
(2), wood-plastic products behave carefully and neatly done body synthetic products, according to requirements can adjust Product Process and formula at random, thus producing the material of different performance and shape, its section bar utilization rate is close to 100%；
(3), the wood of Wood-plastic material/mould base material and the equal Environmental Safety of usual auxiliaries thereof, nontoxic, without having side effects in its process of manufacture, therefore human body and environment are not all constituted any harm；
(4), maintenance cost extremely low, and life of product is several times as much as common natural timber；
(5), the scrap products of Wood-plastic material and reclaim waste product all can 100% regeneration, and without influence on product serviceability.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
