Description

Technical Field

[0001] The patent of this invention relates to the technical field of logistics pallets, specifically a high-impact polystyrene nine-legged logistics pallet and its preparation process. Background Art

[0002] As a core component in modern logistics warehousing, high-impact polystyrene logistics pallets work in conjunction with forklifts, shelves and other logistics equipment to provide efficient solutions for the storage, loading and handling of goods. It is not only an indispensable part of the logistics industry, but also widely praised for its environmental protection and durability. Compared with traditional wooden pallets, high-impact polystyrene pallets significantly reduce dependence on and damage to forest resources, actively responding to the call for environmental protection.

[0003] However, the structures of some high-impact polystyrene logistics pallets on the market are mostly compression molded, and their structures consist of an external shell and an internal support frame, which leads to high production costs. At the same time, during the logistics transportation process, this may cause the goods to slip and be damaged, causing unnecessary losses to the company.

[0004] Invention patent content

[0005] The purpose of the present invention is to provide a high-impact polystyrene nine-legged logistics pallet and its preparation process to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the patent of the present invention provides the following technical solutions: a high-impact polystyrene nine-legged logistics pallet, comprising a pallet and nine legs arranged in a matrix, wherein the pallet is composed of a connecting plate between two adjacent legs, a first hollow groove is arranged at the bottom end of the middle part of the connecting plate, two second hollow grooves are symmetrically arranged at the top ends of both sides of the connecting plate, a third hollow groove is arranged at the bottom end of the leg, and a support frame array is arranged in the first hollow groove, the second hollow groove and the third hollow groove.

[0007] Furthermore, weight-reducing holes are evenly arranged in the first hollow groove along the support frame array.

[0008] The preparation process of the high-impact polystyrene nine-legged logistics pallet implemented based on the emergency lane autonomous control system includes the following steps:

[0009] S1: Main material mixing: weigh the main materials according to the formula, add 100 parts of high impact polystyrene, 20 parts of styrene-butadiene-styrene block copolymer, 15-20 parts of polyborosiloxane, 10-40 parts of flame retardant, 15-20 parts of polyphenylene ether and 3-4 parts of silane coupling agent modified nano titanium dioxide into a mixer and stir and mix evenly at a stirring temperature of 35-45°C for 5-10 minutes;

[0010] S2: Adding additives: Add 5%-20% of plasticizer and 0.05%-0.25% of antioxidant into the mixer and continue stirring for 4-6 minutes to obtain a mixture;

[0011] S3: Open refining: The mixed material is subjected to an open refining treatment at a temperature of 75-95°C for a time of 3-5 minutes to obtain an open refining product;

[0012] S4: Cooling and cutting: After the smelted material is cooled and formed, it is cut into pieces to obtain sheet-shaped pre-finished products;

[0013] S5: Compression molding: Apply a release agent on the mold, then place the sheet pre-finished product into the mold for compression molding, the compression molding temperature is 165-175°C, and the compression molding time is 15-25min;

[0014] S6: Edge trimming: The pre-molded finished product is trimmed to obtain a finished product.

[0015] Preferably, the amount of flame retardant added in step S1 is 35 parts.

[0016] Preferably, the additive added in step S2 also includes 5% rubber.

[0017] The beneficial effects achieved by the present invention are:

[0018] 1. The nine bases and connecting plates arranged in a matrix increase the stability and load-bearing capacity of the pallet. At the same time, the support frame arrays arranged in the first, second and third hollow grooves further strengthen the structure and help prevent the goods from slipping and being damaged during the logistics process.

[0019] 2. The weight-reducing holes provided in the first hollow groove can reduce the weight of the pallet while ensuring its strength, which helps to improve logistics efficiency and reduce transportation costs.

[0020] 3. Each component in the preparation process enhances the toughness and impact resistance of the material through styrene-butadiene-styrene block copolymer, polyborosiloxane and flame retardant improve the fire resistance of the material and increase the safety of the pallet, polyphenylene ether helps to improve the heat resistance and chemical stability of the material, silane coupling agent modified nano titanium dioxide enhances the UV resistance of the material and extends the service life of the pallet, plasticizer increases the flexibility and plasticity of the material, and facilitates processing and molding, antioxidants prevent the material from aging due to oxidation during processing and use, and extend the service life of the pallet, rubber improves the wear resistance and oil resistance of the pallet, and is suitable for a variety of logistics environments.
