Abstract
The invention discloses plastic steel hollow transportation square timber. The plastic steel hollow transportation square timber comprises, by mass, 50 to 80% of a main material, 25 to 30% of an auxiliary material, and 5 to 15% of a synthetic material; the main material comprises PVC resin; the auxiliary material comprises bamboo powder, wood flour, and light weight calcium powder; the synthetic material comprises a foaming agent, a stabilizing agent, and an adhesive. Advantages of a preparation method of the plastic steel hollow transportation square timber are that: finished product strength is high; the foaming agent is added, so that finished product hardness is reduced with the finished product strength is ensured, the plastic steel hollow transportation square timber possesses a certain porosity, and it is convenient to drive nails into the plastic steel hollow transportation square timber when a mould is immobilized on the plastic steel hollow transportation square timber; the plastic steel hollow transportation square timber is prepared by taking PVC resin as the main material, PVC resin is colorless, odourless, and non-toxic, possesses environmental protection flame resistance, and can be recycled, so that material loss and cost are reduced.
Description
Technical field
The present invention relates to a kind of plastic-steel hollow traffic flitch;
The preparation method who the invention still further relates to a kind of plastic-steel hollow traffic flitch, belongs to building traffic field.
Background technology
At present, at China's traffic, the reinforcing of the building trade template back side and load capacity, all adopt flitch.In traffic, flitch generally adopts the specification of 10 ㎝ * 4.0, ㎝ * 10 ㎝, and building trade generally adopts the flitch specification of 5 ㎝ * 4.0, ㎝ * 10 ㎝.Flitch material generally adopts Pseudotsuga menziesii (Mirbel) Franco, kahikatea and wood materials, and flitch is used out of doors, through exposing to the sun and rain, be easy to cause distortion, or make flitch length saw shorter and shorter according to moulding, become waste material, cannot reuse again, cause a large amount of wastes of timber.Therefore develop a kind of plastic-steel hollow flitch, this product meets national industry structure directing, recyclable, can produce, recycle, and energy-conserving and environment-protective, can protect the national forest reserves.We need a kind of type material to make the plastic-steel hollow lumps of wood, substitute field construction and generally adopt a kind of new technology of wooden flitch to solve this problem.
Summary of the invention
The invention provides a kind of plastic-steel hollow traffic flitch and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is: a kind of plastic-steel hollow traffic flitch, flitch comprises major ingredient, auxiliary material and synthetic materials, the per-cent that contains the quality of major ingredient is 50%-80%, mass percent containing auxiliary material is 25%-30%, and the mass percent that contains synthetic materials is 5%-15%, and the material of major ingredient comprises polyvinyl chloride resin, the material of auxiliary material comprises bamboo powder, wood powder, light calcium powder, and the material of synthetic materials comprises whipping agent, stablizer and tackiness agent.
In synthetic materials, add whipping agent, can allow flitch foam, can reduce the hardness of flitch, make flitch with a fixed gap, in fixed die plate, can allow nail easily hammer into; Polyvinyl chloride resin has that colorless and odorless is nontoxic, the speciality of environmental protection flame retardant, and can be recycled, and has reduced the loss of material, has reduced cost.
In technique scheme, polyvinyl chloride resin is PVC-SG5 type resin.
In technique scheme, in synthetic materials, the mass percent of whipping agent is 0.1%-3%.
Add and the hardness of flitch can be reduced to present 45 by original Rockwell hardness 75 after whipping agent.
A method of preparing plastic-steel hollow traffic flitch, step 1: add the speed turning with per minute 1000-1300 in mixer to carry out high speed batch mixing proportionally load weighted major ingredient, auxiliary material and synthetic materials, mixing time is 1-10 minute;
Step 2: will mix material and be warmed up to 100 °-150 °, and make the moisture in mixing material be evaporated to 0.1%-1%, then be warming up to gradually 150 °-180 °, and make batch mixing material become liquid and enter next process;
Step 3: the material that becomes liquid is pushed to forward to custom mold extrusion moulding by volution screw rod, is warming up to gradually 160 °-190 in the process of propelling movement forward;
Step 4: the materials conveyance of extrusion moulding to cooling pool is carried out to water cooling, be cooled to 50 °-70 °;
Step 5: cooling good material is cut according to demand.
In step 2, the moisture in material is evaporated to 0.1%-1%, can increases the intensity of finished product.
In step 4, the material of moulding is carried out to water cooling, water coolant can reuse, and economizes on resources.
Utilization due to technique scheme, the present invention compared with prior art, the advantage having is: it is high that present method is made product intensity, and because added whipping agent in material the inside, can in the situation that guaranteeing product intensity, reduce the hardness of finished product, make flitch with certain space, make on flitch nail in fixed die plate easily squeeze into, and flitch is to be made as major ingredient by polyvinyl chloride resin, polyvinyl chloride resin has again that colorless and odorless is nontoxic, environmental protection flame retardant and the speciality that can be recycled, therefore reduce the loss of material, reduced cost; Finally the material of moulding is carried out to water cooling, water coolant can reuse, and has saved resource; Finished product can cut according to demand, strong adaptability.
