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 invention mainly relates to glass fiber compound material field, relate generally to the production skill of glass fibre composite granule
Art.
Background technology
It is good that thermoplastic possesses lightweight, acid-alkali-corrosive-resisting performance, again can repeatedly recycling, development speed quickly,
For example, for substituting heavy steel form and substituting the plank sheathing being limited by natural resources as building template, it has also become work as this life
A kind of development trend in boundary.But building template is higher to mechanical property and dimensional stability requirements, and require certain heat resistance,
Install and use light, so generally adopting fiber reinforced thermoplastics（RFTP）, based on the requirement of building template size, also difficult
So that forming method is strengthened using LFT or SFT, and adopt LFT or SFT compression molding, not only the problems such as technique, and be difficult to ensure that
Mechanical property is uniform everywhere for template.And adopt GF（Glass fibre）Fabric and thermoplastic plastic sheet's molding produce, due to being difficult to
Make plastic molten mass infiltrate GF fabric very well, the problems such as that is, GF fabric and plastic interface easily exposed, lead to product mechanics
Performance difficult to reach requires.
The present invention directly uses LFT material strip and makes my Ei of fabric group and strengthens sandwich layer, due to LFT material strip production process
In, most of GF has been infiltrated by thermoplastic and has wrapped up, and does enhancing sandwich layer with him, can avoid using being difficult to that GF fabric exists
The problem of infiltration parcel.
Content of the invention
Goal of the invention：For above-mentioned existing problem and shortage, it is an object of the invention to provide a kind of LFT material strip
Fabric strengthens plastic formwork and the production method of sandwich layer.
Technical scheme：For achieving the above object, the present invention employs the following technical solutions：A kind of LFT material strip fabric increases
The plastic formwork of strong sandwich layer, the tissue layer being made up of LFT material strip including multilayer laying, described fabric layer surface and tissue layer
Interlayer is all filled and is enclosed with thermoplastic.
Preferably, the warp thread direction of described adjacent fabric layer is in angle, that is, in every one layer of LFT material strip tissue layer of laying
When, preceding layer makees a suitable deflection angle relatively, and surface is completely overlapped through parallel, and such that it is able to improve, it is anti-shearing and tension is strong
Degree.
Preferably, described tissue layer is braid, woven material or intertexture.
Preferably, described thermoplastic is PP, PE, PA or PVC.
Preferably, the fiber content in LFT material strip in described tissue layer is 25～60%, and a diameter of 1～6mm of material strip.
Another object of the present invention there is provided the producer that a kind of above-mentioned LFT material strip fabric strengthens the plastic formwork of sandwich layer
Method, comprises the following steps：Step 1, tissue layer is made using LFT material strip；Step 2, on request cutting LFT material strip tissue layer is put
Enter in pressing mold, and the thermoplastic molten body extruded from extruder is added in pressing mold, and carry out heating pressurization；Step 3,
Finally cool down, and the demoulding obtains product.
Beneficial effect：Compared with prior art, the present invention has advantages below：The present invention is directly made using LFT material strip
Fabric as strengthen sandwich layer, with respect to GF fabric avoid its be difficult to by thermoplastic molten body complete wetting parcel asking
Topic, improves the mechanical strength of plastic formwork.
Brief description
Fig. 1 is the structural representation of the plastic formwork that LFT material strip fabric of the present invention strengthens sandwich layer；
Fig. 2 is the process flow diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention it should be understood that these embodiments are merely to illustrate
The present invention rather than restriction the scope of the present invention, after having read the present invention, those skilled in the art are each to the present invention
The modification planting the equivalent form of value all falls within the application claims limited range.
As shown in Fig. 1～2, the production method flow process that the LFT material strip fabric of the present invention strengthens the plastic formwork of sandwich layer is as follows：
Directly establishment is carried out using LFT material strip and form tissue layer；The thermoplastic plastic sheet cutting is put in pressing mold, then successively
LFT material strip tissue layer is laid in pressing mold, in laying, later layer LFT material strip tissue layer is suitably rotated an angle
Stagger, finally place into one layer of thermoplastic plastic sheet in the superiors；Pressing mold is carried out with heating pressurization, after certain time, cools down,
The demoulding obtains product.
In above-mentioned production process, more actual requirement thermoplastic can adopt PP, PE, PA or PVC.
