Abstract
The invention discloses a plastic formwork of an LFT material strip fabric reinforcing core layer and a producing method of the plastic formwork. The plastic formwork comprises a plurality of layers of stacked fabric layers made of LFT material strips, and surfaces of the fabric layers and interlamination of the fabric layers are filled with and covered with thermoplastic plastics. According to the plastic formwork of the LFT material strip fabric reinforcing core layer and the producing method of the plastic formwork, the fabric layers made of the LFT material strips are used as the reinforcing core layer, the problem that GF fabric layers cannot be easily infiltrated and covered by the thermoplastic plastic melt bodies completely is solved, and the mechanical strength of the plastic formwork is improved.
Description
Technical field
The present invention relates generally to the glass fiber compound material field, relates generally to the production technology of glass fiber composite granule.
Background technology
Thermoplastic possesses lightweight, the acid-alkali-corrosive-resisting performance is good, repeatedly recycling again, development speed is very fast, for example, be used for substituting heavy steel form and the alternative wooden form that is subjected to the natural resource restriction as construction formwork, become a kind of development trend in the world today.But construction formwork is had relatively high expectations to mechanical property and dimensional stability, and require certain heat resistance, install and use light, so usually adopt fiber reinforced thermoplastics (RFTP), based on the requirement of construction formwork size, also be difficult to adopt LFT or SFT to strengthen forming method, and adopt LFT or SFT compression molding, the problem such as technique not only, and mechanical property is even everywhere to be difficult to guarantee template.And employing GF(glass fiber) fabric and thermoplastic plastic sheet's mold pressing production, owing to being difficult to make the fine infiltration of plastic molten mass GF fabric, namely GF fabric and plastic interface easily occur the problems such as exposed causing Mechanical Properties of Products to be difficult to reach requirement.
The present invention directly adopts is that the LFT material strip is made I Ei of fabric group and strengthened sandwich layer, in LFT material strip manufacturing process, most of GF is infiltrated by thermoplastic and wraps up, and does the enhancing sandwich layer with him, can avoid the problem that is difficult to infiltrate parcel that adopts GF fabric problem.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this invention is to provide plastic formwork and production method that a kind of LFT material strip fabric strengthens sandwich layer.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of LFT material strip fabric strengthens the plastic formwork of sandwich layer, comprise the tissue layer of being made by the LFT material strip of multilayer laying, the equal filling bag of the interlayer of described fabric layer surface and tissue layer is wrapped with thermoplastic.
As preferably, the warp thread direction of described adjacent tissue layer is angle, namely when every laying one deck LFT material strip tissue layer, relatively before one deck make a suitable deflection angle, surperficial graticule is fully overlapping, thereby can improve its anti-shearing and tensile strength.
As preferably, described tissue layer is braid, woven material or intertexture.
As preferably, described thermoplastic is PP, PE, PA or PVC.
As preferably, the fiber content in described tissue layer in the LFT material strip is 25～60%, and the material strip diameter is 1～6mm.
Another purpose of the present invention has been to provide the production method that a kind of above-mentioned LFT material strip fabric strengthens the plastic formwork of sandwich layer, comprises the following steps: step 1, employing LFT material strip are made tissue layer; Step 2, on request cutting LFT material strip tissue layer is put into to pressing mold, and will join pressing mold from the thermoplastic molten body that extruder is extruded, and heat pressurization; Step 3, finally cooling, and the demoulding obtains goods.
Beneficial effect: compared with prior art, the present invention has the following advantages: the present invention directly adopts fabric that the LFT material strip makes as strengthening sandwich layer, with respect to the GF fabric, avoided it to be difficult to, by the problem of thermoplastic molten body complete wetting parcel, improve the mechanical strength of plastic formwork.
The accompanying drawing explanation
Fig. 1 is the structural representation that LFT material strip fabric of the present invention strengthens the plastic formwork of sandwich layer;
Fig. 2 is process flow diagram of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention be used to the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Fig. 1～2, the production method flow process of the plastic formwork of LFT material strip fabric enhancing sandwich layer of the present invention is as follows: directly adopt the LFT material strip to work out and form tissue layer; The thermoplastic plastic sheet who cuts is put into to pressing mold, then successively by LFT material strip tissue layer lay in pressing mold, later layer LFT material strip tissue layer is carried out to suitably rotate an angle when laying and stagger, finally in the superiors, put into again one deck thermoplastic plastic sheet; Pressing mold is heated to pressurization, and after certain hour, cooling, the demoulding obtains goods.
In above-mentioned manufacturing process, the actual requirement thermoplastic can adopt PP, PE, PA or PVC more.
