Embodiment 1

[0042] According to the weight ratio of each component, 100 parts of biodegradable masterbatch, 40 parts of EVA, 40 parts of LDPE, filler CaCO 3 80 parts, 0.3 part of crosslinking agent (DCP) dicumyl peroxide, 3 parts of foaming agent (Ac) butane, 0.7 part of stabilizer calcium stearate, 0.5 part of lubricant stearic acid, nucleating agent powder 0.05 parts of silicon dioxide and 0.4 parts of colorant titanium dioxide were put into a low-speed mixer and stirred for 5 minutes to prepare a blend. Add the blend to the masticator for mastication. The roller temperature of the plasticizer is 160°C±2°C, and the sheet is plasticized for 15 minutes, and the sheet is placed in a hot press for 10 minutes and the pressure is 12-15Mpa. Take out the pressed tablet and trim the corners to make a sheet of a specified size, cut the sheet of a specified size into a small-sized sheet with a slicer, put the small-sized sheet into a molding machine, and press the mold with a steam pressure of 0...

[0045] According to the weight ratio of each component, 100 parts of biodegradable masterbatch, 40 parts of EVA, 40 parts of LDPE, filler CaCO 3 80 parts, 0.3 part of crosslinking agent (DCP) dicumyl peroxide, 3 parts of foaming agent (Ac) butane, 0.7 part of stabilizer calcium stearate, 0.5 part of lubricant stearic acid, nucleating agent powder 0.05 parts of silicon dioxide and 0.4 parts of colorant titanium dioxide were put into a low-speed mixer and stirred for 5 minutes to prepare a blend. Add the blended material to the plastic mixer for plastication. The roller temperature of the plastic mixer is 160°C±2°C. Plasticize for 12 minutes to pull the sheet. Put the sheet in a hot press for 10 minutes and press it at a pressure of 12-15Mpa. , take out the pressing sheet and trim the corners to make a sheet of standard size. Use a granulator to make pellets from the sheets with specifications and sizes, put the pellets into the extruder, extrude and foam at the same time, the m...

Abstract

The invention refers to a biodegradable complex material, the making method and the use. It uses biodegradable mother material as main material, mixes together with EVA, PE, filler, cross-linking agent, vesicant, stabilizing agent, lubricant, colorant and nucleating agent, and get the material through plastication, calendering, flaking, slicing, moulding pressing, foaming and so on. The material can be made into degradable shoe material and aseismatic piece material for packing.

Description

technical field [0001] The invention relates to a biodegradable composite material and its manufacturing method and application, in particular to a composite material used for degradable shoe materials and shock-resistant sheets for degradable packaging. The composite material is made of biodegradable masterbatch The main material is made. Background technique [0002] At present, the main components of shoe materials and shock-resistant sheets for packaging on the market are PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), EVA (ethylene-vinyl acetate copolymer), rubber, etc. Petrochemical products, they are all high polymers, because of the high degree of polymerization and strong intermolecular force, the polymer chains are difficult to break and decompose, which leads to the non-degradability of existing shoe materials and shock-resistant packaging sheets, which will pollute environment. At the same time, petroleum is a non-renewable resource on the eart...
