Problems solved by technology

[0004] In the above patents, although the wear resistance of the polypropylene sheet has been improved through various methods, the process is mainly hot pressing, gluing, and sintering, and the operation is complicated and time-consuming.
And because polypropylene is non-polar, it is more difficult to bond with other polar materials, and it is easy to peel off, resulting in poor performance stability of the board

Abstract

The invention discloses a polypropylene plate production equipment, which comprises a coil placement device, a heating device, a pressing device and a traction device, and the above parts are connected in sequence. The coil placement device includes a front film roll frame (11) and a rear film roll frame (12); the heating device includes a front infrared heating lamp tube (51) and a rear infrared heating lamp tube (52); the pressing The device includes a front pressure roller (41) and a rear pressure roller (42), forming a pressing device through pneumatic pressure; the traction device includes a front traction guide roller (31) and a rear traction guide roller (32), and the pressure Form a traction device. The invention also discloses a method for preparing polypropylene sheets by using the above-mentioned production equipment: according to the order from top to bottom, the front film layer, the rear film layer, and the polypropylene sheet are laid flat, pressed, heated, and pulled to obtain the polypropylene sheet. sheet. The production equipment of the invention can be conveniently connected with the extrusion equipment of the polypropylene plate to realize online continuous production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a production equipment of polymer materials and a preparation method thereof. Background technique [0002] Polypropylene material has excellent corrosion resistance and processability, low water absorption and low price, so it is very suitable as a plate material. However, the surface hardness of polypropylene resin itself is not enough to deal with long-term friction, damage, etc. At present, the most commonly used method is to reinforce, fill, alloy, etc., but even so, the wear resistance and puncture resistance of polypropylene sheets are still not satisfactory. [0003] For the wear-resistant and puncture-resistant treatment of the material, the patent CN 202945694U uses a 150-200 μm polyurea coating and glass fiber cloth. Patent CN 103240929A uses continuous glass fiber reinforced polypropylene prepreg tape, fine steel wire mesh, glass fiber / polypropylene felt as ...
