A kind of hygienic environment-protecting is sticking cage pad and preparation method thereof not
Technical field
The present invention relates to food processing field, especially relate to not sticking cage pad and preparation method thereof of a kind of hygienic environment-protecting.
Background technology
Dragons and fishes jumbled together in market for cage pad (cage cloth) now, and gauze, straw pad and disposable PP cage cloth are arranged, and also has many retailers to work as the cage pad with the Polywoven Bag of packing chemical fertilizer or cement.There are a very stubborn problem in gauze and straw pad, i.e. wheaten food and mat adhesion is very serious, the bottom of steamed bun (or steamed stuffed bun) by sticking descend a bulk of, one, influenced the attractive in appearance of steamed bun (or steamed stuffed bun), two, caused serious waste.And mat utilize the program more complicated again: need rub repeatedly and wash and could the dough that be stained be washed, time-consuming, effort, water wasting.The time that this mat is used can be not oversize, was generally 1 month, because at high temperature steam for a long time, it is rotten that gauze and straw mattress can become, and strength loss totally has to more renew.Long-time gauze or the straw mattress that uses is easy to assemble dirt, straw mattress especially, and inner because a lot of dirt gets into the grass blade of straw mattresses, extremely difficulty is cleaned out, very easy breed bacteria.
China utility model CN200945111 discloses a kind of disposable PET food steamer cloth, is made up of substrate, and the food steamer cross sectional shape that said substrate shape is used to it is complementary, and its surface is provided with antistick layer, and this antistick layer and substrate are combined closely.During use, as long as be tiled in the food steamer cloth of the utility model on the food steamer steaming lattice, the steamed stuffed bun or the dumpling of preparatory boiling placed on the food steamer cloth, the boiling of opening fire gets final product.Because food steamer cloth surface scribbles the antistick layer of grease emulsifier, make well-done steamed stuffed bun of steaming or dumpling can not glue food steamer cloth, therefore can guarantee that steamed stuffed bun or dumpling can not break, and remove the loaded down with trivial details washing labor service of people with disposable use.This utility model patent adopts disposable adhesive-bonded fabric PET, has improved cost greatly, promotes commercial being not suitable for.
In the existing cage pad manufacturing technology, adopt Polywoven Bag or Polypropylence Sheet to work as the cage pad and can prolong service time, but also there is fatal defective in he.Be that this antihygienic plastics at high temperature can discharge toxin, in the process of steaming, toxin can immerse food naturally, and is very big to diner's health effect.
Up to now, do not find that also the food grade plastic with injection moulding or braiding is used as the report of cage pad.
Summary of the invention
The object of the invention is exactly to provide a kind of material and wheaten food sticking for the defective that overcomes above-mentioned prior art existence; Convenience for washing; Only needing water to dash can wash away surface or inner filth, long hygienic environment-protecting service time sticking cage pad and preparation method thereof.
The object of the invention can be realized through following technical scheme: the not sticking cage pad of a kind of hygienic environment-protecting is characterized in that this cage pad comprises following component and weight portion content:
Food grade materials 100;
Non-toxic heat stabilizer 0.5-5.6;
Nontoxic hydrolysis-resisting agent 0.5-5.6.
Described food grade materials is selected from one or more in food-grade TPO material, food-grade aromatic polyester class material, the polyamide-based material of food-grade.
Described food-grade TPO material is selected from the homopolymers of alpha-olefins such as ethene, propylene, 1-butylene, 1-amylene, 1-hexene, 1-octene, 4-methyl-1-pentene and cycloolefin or in the copolymer one or more.
Described food-grade aromatic polyester class material is selected from one or more in PETP (PET), polytrimethylene terephthalate (PTT), the polybutylene terephthalate (PBT).
The polyamide-based material of described food-grade is selected from one or more of two 6 (PA66) of nylon list 6 (PA6), nylon, nylon 12 (PA12), nylon 46 (PA46), NYLON610 (PA610), nylon 612 (PA612), nylon 1010 (PA1010).
Described non-toxic heat stabilizer is selected from zinc stearate, calcium stearate, one or more in the dolomol.
Described nontoxic hydrolysis-resisting agent is the Carbodiimides hydrolysis-resisting agent, comprises two (2, the 6-diisopropyl phenyl) carbodiimides.
A kind of hygienic environment-protecting is the preparation method of sticking cage pad not, it is characterized in that this method may further comprise the steps:
(1) prepare raw material according to following component and weight portion content:
Food grade materials 100;
Non-toxic heat stabilizer 0.5-5.6;
Nontoxic hydrolysis-resisting agent 0.5-5.6;
(2) above-mentioned raw materials is extruded with twin-screw;
(3) material that step (2) is obtained directly is injection molded into mesh shape goods, or is extruded into fine strip shape through extruder again and then carries out knitting forming.
Described mesh shape product is meant circle, ellipse, criss-cross, rhombus, pentagon or hexagonal sheet product of the hollow out that is distributed with continuous distributed on it; The thickness of described mesh shape goods is 0.1mm~10mm.
The diameter of described fine strip shape is 0.1mm~10mm, and the weaving method of its knitting forming comprises slide fastener, chain, and three strands of pigtails, spiral, two direct rotary or draw back.
Compared with prior art, what the not sticking cage pad of the present invention was used is nontoxic food grade plastic, does not contain harmful additive and various auxiliary agent in the plastics.This invention biggest advantage is that material and wheaten food are not sticking, convenience for washing, and only needing water to dash can wash away surface or inner filth.Service time is long, and through experiment, the cage pad of injection moulding used after 12 months, and is indeformable, and not aging, significant change does not take place mechanical property basically.Relative gauze or straw mattress, this novel cage pad life cycle is long, and cost is low, convenience attractive in appearance.
