Background technology
Plastic film is a kind of common plastic products, it can be given birth to by processes such as rolling process, extrusion molding, blowings
Production, inflation film are that plastic raw materials are extruded into light wall pipe raw material melting by extruder, are then while hot blown it with compressed air
It is swollen, up to film article after cooling and shaping.Purposes is extremely wide in modern society for film article, various types of thin
Membrane product respectively has its purposes, is widely used in packaging field such as low-density polyethylene film, as low-density polyethylene film is
The main material of food packaging.Polyethylene film is also used as application of civil engineering in civil engineering and agricultural film used in agriculture
Deng.But as environmental problem is on the rise, state and society appeals more environmentally protective thin-film material, it is desirable that film into
This is relatively low, raw material reproducible utilization, film being capable of natural degradation, environmentally friendly.A kind of current resolving ideas is to use
Film is made by mixing in organic matter and soil matrix, but it faces the technical issues of serious, and most important is exactly that cost is excessively high, formula
In it is very low to reducing the vital soil matrix accounting of cost, less than 15%, organic material and auxiliary material accounting are excessively high, and cost is caused to occupy
It is high not under.In addition, during traditional soil matrix material blown film, it is poor that fold, film clarity occurs in FAQs such as film, flake
Volume etc. is run when more, uneven film thickness, winding, seriously affects soil matrix film quality.
Invention content
It is an object of the invention to overcome the shortcoming of above-mentioned traditional technology, it is relatively low, friendly to environment to provide a kind of cost
It is good, natural degradation, raw material can use the new energy soil matrix blown film material and production technology of recyclable materials in the environment.
The purpose of the present invention is what is reached by following technical measures：
A kind of new energy soil matrix blown film material, ingredient are made of the raw material of following mass percent：Modified kaolin 55--
60%th, crosslinking agent 0.55--0.6%, polylactic acid 39.4--44.45%.
As a preferred embodiment, the crosslinking agent is cumyl peroxide（DCP）.
As a preferred embodiment, the modified kaolin is through the organically-modified kaolin of Eighteen alkyl acid.
As a preferred embodiment, the granularity of the modified kaolin for 325 mesh and more than.
A kind of new energy soil matrix blown film production technology：Change by the mass percent preparation of above-mentioned new energy soil matrix blown film material
Property kaolin, crosslinking agent and polylactic acid, by modified kaolin, crosslinking agent and polylactic acid add in high-speed mixer mix, Ran Houjin
Enter in double screw extruder and be crosslinked, it is in situ to disperse, the soil matrix blown film material of molten condition is obtained, through inflation film manufacturing machine blown film.
As a preferred embodiment, temperature is controlled in 30--60 degree during the high-speed mixer mixing.
As a preferred embodiment, rotating speed 2250--2750r/min during the high-speed mixer mixing.
As a preferred embodiment, high-speed mixer incorporation time 3--8 minutes.
As a preferred embodiment, temperature is controlled in 180-195 degree in the double screw extruder.
The present invention uses polylactic acid to be combined for binding agent with modified kaolin, forms soil matrix blown film material.The present invention uses
Polylactic acid, also referred to as polylactide (polylactide) belongs to polyester family, belongs to renewable, free of contamination new energy material
Material, in the present invention substituting petroleum base.Polylactic acid is the polymer obtained using lactic acid as main polymerizable raw material, raw material sources
It fully and can regenerate, mainly with corn, cassava etc. for raw material.The production process of polylactic acid is pollution-free, and product can be with
The cycle in nature is realized in biodegradation, therefore is ideal Green Polymer Material.
The present invention is based on polylactic acid and modified kaolin, addition crosslinking agent, and the soil matrix film of preparation has thermal stability
Feature well, the solvent resistance having had can not only be biodegradable outer, biocompatibility, glossiness, the transparency, feel and heat-resisting
Property is good, and also with certain fungus resistance, anti-flammability and ultraviolet-resistent property, therefore purposes is very extensive, can be used as packaging material, fiber
With non-woven fabric etc., it is currently used primarily in the industries such as the clothes such as underwear, coat, building, agricultural, forestry, papermaking and health care
The fields of grade.This product can substitute now widely used oil base film, such as PP, PVC, because petroleum base is non-renewable
Raw material, it is non-renewable, and natural degradation is difficult to, it causes serious pollution to the environment, this product belongs to renewable, free of contamination new energy
Source material can be very good to solve the above problems, and the soil matrix film performance can match in excellence or beauty with oil base film.This product can be with
Petroleum base is substituted, white pollution is solved, preferably protects environment for human survival.
It is examined through product quality inspection research institute of Shandong Province, film product sealing strength 12.8N/15mm of the invention, it is high
It has a surplus again in the N/15mm mono- of standard >=6.0, product drop performance（Highly：500mm is freely fallen 1 time）It does not rupture, meets BB/
The requirement of T0039-2013 standards.
By adopting the above-described technical solution, compared with prior art, it is an advantage of the invention that：
The invention discloses a kind of new energy soil matrix blown film material and production technology, using a high proportion of modified kaolin and can be again
Raw, free of contamination new energy materials polylactic acid adds crosslinking agent, soil matrix film is made, and constituent derives from a wealth of sources, and poly- breast
Acid can regenerate, and the soil matrix film of preparation has the characteristics that thermal stability well, the solvent resistance having had, can not only be biodegradable
Outside, biocompatibility, glossiness, the transparency, feel and heat-resist, also with certain fungus resistance, anti-flammability and uvioresistant
Property, therefore purposes is very extensive, can be used as packaging material, fiber and non-woven fabric etc., is currently used primarily in the clothes such as underwear, coat
The fields such as industries and health care such as dress, building, agricultural, forestry, papermaking can substitute petroleum base, solve white pollution, more
Protect environment for human survival well.
The invention will be further described With reference to embodiment.
