The invention adopts the combination process of continuous fiber reinforced plastics and fixed length fiber reinforced plastics, and the combination of plastic particles with different lengths ensures that the supporting plate has the advantage of light weight of plastic products, and meanwhile, the strength of the plastic supporting plate can reach the strength of steel and is not easy to corrode.
Description
Technical Field
The invention belongs to the field of plastic supporting plate preparation, and particularly relates to a preparation process of a high-strength plastic supporting plate.
Background
Pallets, also known as pallets, are one type of logistics handling equipment. The material is distinguished, and the supporting plate can be a wooden supporting plate, a steel supporting plate, a glued supporting plate and a plastic supporting plate. Wooden layer board low in manufacturing cost and simple process, the dead weight is also lighter, but wooden layer board's bearing does not have the good of other materials, and wooden layer board is easy to receive rain and moist rotten because of the reason of its self material moreover, has consequently restricted wooden layer board's use. The steel supporting plate has the advantages of high strength, firm structure and stable material, but the steel supporting plate has a heavier weight and limits the use to a certain extent. Plastic pallets are lightweight, corrosion resistant, and have good integrity, and are the mainstream of modern logistics, but some. The manufacturing cost of the plastic pallet is high, the bearing of some plastic pallets cannot meet the requirement, and with the development of logistics, the plastic pallet which is lighter, simple in preparation process and capable of maintaining higher bearing becomes one of the technical difficulties in the field.
Disclosure of Invention
The invention discloses a preparation process of a high-strength plastic supporting plate, aiming at the problems in the prior art, the plastic supporting plate is added with the combination of continuous fiber reinforced plastics, fixed-length fiber reinforced plastics and recycled plastics, and the supporting plate prepared from the plastics can be used for wooden trays, supporting plates and other plastic trays and supporting plates in the prior art and has stronger rigidity and toughness.
The invention is realized by the following steps:
the preparation process of the high-strength plastic supporting plate comprises the following components in parts by mass: continuous fiber reinforced plastic: 40 to 100 portions; fixed-length fiber reinforced plastic: 0 to 100 portions; and (3) recycled plastic: 0 to 70 portions.
Further, the continuous fiber reinforced plastic is a continuous fiber reinforced plastic rod or a continuous fiber reinforced plastic sheet; the continuous fiber reinforced plastic comprises: natural fibers, glass fibers, chemical fibers, carbon fibers, plastics; the plastic is one or more of PP (polypropylene), PE (polyethylene), PA (nylon), PEP (PEP) and PBT; the content of the natural fiber and the glass fiber is 30-80%; the fiber length of the continuous fiber reinforced plastic can be equal to the length and width of the product.
Further, the fixed-length fiber reinforced plastic is continuous fiber reinforced plastic particles of 5-50 cm, and specifically, the continuous fiber reinforced plastic is cut into particles of 5-50 cm in length.
Furthermore, the recycled plastic is recycled plastic by crushing.
Further, the preparation process specifically comprises the following steps: step one, weighing and mixing materials: uniformly mixing 40-100% of the fixed-length fiber reinforced plastic and 0-70% of the regenerated plastic particles; secondly, putting the mixed material into a charging barrel of an extruder, heating the extruder for extrusion, and melting the material; extruding the molten material through an extruder, weighing, cutting and shearing to 5-50 cm; step four, preheating or not preheating the continuous fiber reinforced plastics; step five, putting the step three and the step four into a die cavity for pressure forming; step six, pressure maintaining and demoulding; and step seven, demolding and trimming.
The beneficial effects of the invention and the prior art are as follows:
wooden layer board among the prior art is perishable and intensity is not high, if adopt the layer board of steel then increase the inconvenient use of quality of layer board on the basis of goods originally. The invention adopts the combination process of continuous fiber reinforced plastics and fixed length fiber reinforced plastics, and the combination of plastic particles with different lengths ensures that the supporting plate has the advantage of light weight of plastic products, and meanwhile, the strength of the plastic supporting plate can reach the strength of steel and is not easy to corrode.
