Abstract
The invention provides biochemical degradable polyolefin foam, as well as a manufacturing method and an application thereof. The polyolefin foam comprises the following components in weight percentage: 60 to 65 percent of vegetable fiber, 31 to 37 percent of PP water gap material and 3 to 6 percent of lubricant. The manufacturing method mainly comprises the following: a step of preparing materials, which is to prepare the vegetable fiber, the PP water gap material and the lubricant according to the formulation; a step of mixing the materials at high speed, which is to mix the materials in a high-speed mixer at a temperature of 120+/-10 DEG C; a step of granulating, which is to extrude, cut and granulate the well-mixed materials by use of a double-screw extruder within the temperature range from 150 to 175 DEG C; a step of soaking, which is to soak the extruded granules in tap water for 20 to 30 hours; and a step of foaming, which is to extrude the soaked materials into foaming strip by use of a single-screw extruder within the temperature range from 170 to 190 DEG C. The polyolefin foam has the advantages of no toxicity, hygiene, environmental protection, degradability and the like, and is mainly applied to buffer shockproof packaging materials.
Description
Technical field
The present invention relates to a kind of biochemical degradation of polyolefin foam and manufacture method thereof and application.
Background technology
In late 1960s, some foreign scholars gain enlightenment from the phenomenon of macromolecule material aging, and the degradable plastics that begins one's study tries hard to solve serious day by day plastic refuse pollution problem.In decades, people are making comparatively extensive studies aspect part degradative plastics, the biological decomposition material.China's biological decomposition material mainly concentrates on vegetable fibre such as straw fiber plastics and two aspects of starch plastic; the starch plastic goods are used more extensive; but; starch is biological main food source; be used to make the starch plastic goods in a large number; certainly will cause crisis in food, and also there is intensity problem low, soluble in water in the plastics made from starch.Make full use of vegetable fibre, waste agronomic crop especially seems very urgent as depleted wood fibre, corn fibre, bamboo fibers, sugarcane rod fibers or cornstalk fiber as one of raw material of degradative plastics.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, provide a kind of biochemical degradation of polyolefin foam that utilizes waste agronomic crop for main raw material to society, and method and the purposes of making this biochemical degradation of polyolefin foam.
Technical scheme of the present invention is: a kind of biochemical degradation of polyolefin foam is provided, comprises following component by weight percentage:
Vegetable fibre 60-65%
PP mouth of a river material 31-37%
Lubricant 3-6%
Described vegetable fibre comprises wood fibre, corn fibre, bamboo fibers, sugarcane rod fibers or cornstalk fiber and composition thereof.
Described lubricant comprises external lubricant and internal lubricant, and the weight ratio of described external lubricant and internal lubricant is 1:3.
A kind of method of making biochemical degradation of polyolefin foam comprises the steps:
(A) material is prepared, and is ready to vegetable fibre, PP mouth of a river material and lubricant by above-mentioned prescription;
(B) high speed batch mixing, in high speed mixer with 120 ℃ ± 10 ℃ high-speed mixing;
(C) granulation is extruded the cutting granulating with dual-screw-stem machine with the material after mixing in 150 ℃ to 175 ℃ temperature ranges;
(D) soak, the material grain of extruding was soaked 20 hours to 30 hours with tap water;
(E) foaming is with the material single-screw machine extrusion foaming bar in 170 ℃ to 190 ℃ temperature ranges after soaking.
The application of the biochemical degradation of polyolefin foam of above-mentioned prescription on amortizing packaging material.
The present invention contains the part farm waste, comprise from formed high fiber residual substances in harvesting processing back such as rice, corn, wheat, barley and bamboos, so the present invention not only can natural biochemical degradation, and can pass through the chemical fertilizer chemical degradation, meets the environmental protection general orientation.
It is mainly used in buffering shock-resistant packaging material aspect.
Embodiment
Following vegetable fibre includes but not limited to wood fibre, corn fibre, bamboo fibers, sugarcane rod fibers or cornstalk fiber and above-mentioned two or more mixture of different fibers thereof.Wood fibre is the wood powder more than 60 orders of wearing into wood chip; Corn fibre is the flour more than 60 orders of wearing into husk; Bamboo fibers is the above bamboo powder of wearing into discarded bamboo of 60 orders; The sugarcane rod fibers is the above cane powder of wearing into the sugarcane bar of 60 orders; Cornstalk fiber is the Semen Maydis powder more than 60 orders of wearing into corn stalk.Lubricant is divided into external lubricant and internal lubricant, the weight ratio of external lubricant and internal lubricant is 1:3, wherein external lubricant can adopt the PP high-tech lubricant that Tianjin, Nanjing intelligent merchant's science, industry and trade company limited provides, and also can adopt the analogous products of other model, and PP mouth of a river material is a polypropylene mouth of a river material.
