preparation example Construction

[0054] The present invention also provides a preparation method of the logistics tray, comprising the following steps:

[0055] (1) polyvinyl chloride, stabilizer, modifying agent, blowing agent, foam regulator and lubricant are mixed to obtain the first mixture;

[0056] (2) heating the first mixture to a first-order temperature and mixing it with rare earth ferrosilicon alloy ash to obtain a second mixture;

[0057] (3) raising the temperature of the second mixture to the second-order temperature and then lowering to the third-order temperature for insulation, and finally lowering to room temperature to obtain the raw material mixture;

[0058] (4) using the raw material mixture to extrude respectively to obtain a base member and a panel member;

[0059] (5) Assemble the base component and the panel component to obtain a logistics tray.

[0060] The invention mixes polyvinyl chloride, stabilizer, modifying agent, foaming agent, foam regulator and lubricant to obtain the fi...

Embodiment 1

[0072] According to the composition of mass parts: 40 parts of rare earth ferrosilicon alloy ash, 47 parts of PVC (8 series), 3 parts of lead salt composite stabilizer, 4 parts of modifier (dioctyl phthalate), foaming agent (azo Diformamide and sodium bicarbonate are used together, mass ratio is 1:2) 1.5 parts, foam regulator (polymethyl acrylate) 4 parts, first lubricant stearic acid 0.3 parts, second lubricant (paraffin wax) 0.2 parts are weighed;

Abstract

The invention belongs to the technical field of logistics trays, and provides a rare earth ferrosilicon alloy ash-based composite material which is prepared from 30 to 40 parts of rare earth ferrosilicon alloy ash, 47 to 57 parts of polyvinyl chloride, 2 to 3 parts of stabilizer, 2 to 4 parts of modifier, 1.5 to 2.5 parts of foaming agent, 4 to 8 parts of foaming regulator, and 0.2 to 0.6 part oflubricating agent. The invention further provides a logistics tray obtained through the rare earth ferrosilicon alloy ash-based composite material. The tray has the characteristics of reasonable structure design, simple structure, light weight, high bearing capacity, good waterproofness and corrosion resistance, reusability and the like. It is shown, by the embodiment result, that the density of the logistics tray provided by the invention is 0.61 to 0.7 g / cm<3>, and the static bending intensity is 32 to 40 MPa. The invention further provides a preparation method of the logistics tray. The preparation method is energy-saving, clean, simple and convenient.

Description

technical field [0001] The invention relates to the technical field of logistics pallet materials, in particular to a rare earth ferrosilicon alloy ash-based composite material, a logistics pallet and a preparation method thereof. Background technique [0002] Rare earth ferrosilicon alloy ash is a solid waste produced during the smelting process of ferrosilicon alloys. The fineness can reach more than 200 mesh. If it is not disposed of properly, it will easily disperse in the air and cause harm to the human respiratory tract. [0003] At present, the pallets used to carry items on the market mainly include wooden pallets, plastic pallets and steel pallets according to their materials, but each has irreparable shortcomings: wooden pallets are perishable after being exposed to moisture, and iron nails for assembly are easy Exposure to the outside will damage the appearance of the product; ordinary plastic pallets have low strength, low load-bearing capacity, poor flexibility ...
