Abstract
The invention relates to a healthy and environment-friendly non-sticky cage pad and a preparation method thereof. The healthy and environment-friendly non-sticky cage pad is a novel cage pad which is made of food grade polyolefin, polyester, polyamide or polymer blends or copolymers thereof and overcomes the defect that the traditional cage cloth or straw pad and food (cooked wheaten food such as steamed bread, steamed stuffed bun or steamed stuffed bun, etc.) are sticky seriously; in addition, compared with the traditional cage cloth or straw pad, the healthy and environment-friendly non-sticky cage pad is clean and healthy, is easy to wash and clean, and can be repeatedly used for a long time. The healthy and environment-friendly non-sticky cage pad has low formula cost, easily controlled process conditions, good product performance and stable quality. So far, the report about a novel environment-friendly non-sticky cage pad has never been heard at home and abroad, so the healthy and environment-friendly non-sticky cage pad provided by the invention has a wider market development prospect.
Description
Technical field
The present invention relates to food processing field, especially relate to not sticky 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, has gauze, straw pad and disposable PP cage cloth, also has many retailers to work as cage pad with the Polywoven Bag of packing chemical fertilizer or cement.There is a very stubborn problem in gauze and straw pad, i.e. wheaten food and mat adhesion is very serious, and the bottom of steamed bun (or steamed stuffed bun) is glued lower a bulk of, and one, affected the attractive in appearance of steamed bun (or steamed stuffed bun), two, caused serious waste.And the recycling program comparision of mat is complicated: need to repeatedly rub and wash and the dough being stained with could be washed down, time-consuming, effort, water wasting.The time that this mat is used can be not oversize, is 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 using is easy to assemble dirt, straw mattress especially, and inner because a lot of dirt enters the grass blade of straw mattress, extremely difficulty is cleaned out, very easy breed bacteria.
China utility model CN200945111 discloses a kind of disposable PET bamboo steamer cloth, substrate, consists of, and the food steamer cross sectional shape that described substrate shape is used to it matches, and its surface is provided with antistick layer, and this antistick layer and substrate are combined closely.During use, as long as bamboo steamer cloth of the present utility model is laid in to food steamer, steam on lattice, the steamed stuffed bun of pre-boiling or dumpling are placed on bamboo steamer cloth to the boiling of opening fire.Because bamboo steamer cloth surface scribbles the antistick layer of grease emulsifier, make well-done steamed stuffed bun or dumpling can not glue bamboo 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 greatly cost, is commercially not suitable for promoting.
In existing cage pad manufacturing technology, adopt Polywoven Bag or Polypropylence Sheet to work as cage pad and can extend service time, but also there is fatal defect in him.Be that this antihygienic plastics at high temperature can discharge toxin, in the process of steaming, toxin can immerse food naturally, very large to diner's health effect.
Up to now, also do not find to be used as by the food grade plastic of injection moulding or braiding the report of cage pad.
Summary of the invention
Object of the present invention is exactly to provide a kind of material and wheaten food sticky in order to overcome the defect of above-mentioned prior art existence, easy to clean, only needing water to rush can wash away surface or inner filth, and service time, long hygienic environment-protecting did not glue cage pad and preparation method thereof.
Object of the present invention can be achieved through the following technical solutions: the not sticky cage pad of a kind of hygienic environment-protecting, it is characterized in that, and this cage pad comprises following component and weight portion content:

Described food stage TPO material is selected from the homopolymers of the alpha-olefins such as ethene, propylene, 1-butylene, 1-amylene, 1-hexene, 1-octene, 4-methyl-1-pentene and cycloolefin or one or more in copolymer.
Described food stage aromatic polyester class material is selected from one or more in PETP (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT).
The polyamide-based material of described food stage 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 dolomol.
Described nontoxic hydrolysis-resisting agent is Carbodiimides hydrolysis-resisting agent, comprises two (2,6-diisopropyl phenyl) carbodiimides.
Hygienic environment-protecting is a preparation method for sticky cage pad not, it is characterized in that, the method comprises the following steps:
(1) according to following component and weight portion content, prepare raw material:
Food grade materials 100;
Non-toxic heat stabilizer 0.5-5.6;
Nontoxic hydrolysis-resisting agent 0.5-5.6;
(2) by above-mentioned raw materials twin-screw extrusion;
(3) material step (2) being obtained is directly injection molded into mesh shape goods, or through extruder, is extruded into fine strip shape again and then carries out knitting forming.
Described mesh shape product refers to circle, ellipse, criss-cross, rhombus, pentagon or the hexagonal sheet product that is distributed with the hollow out of 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 pull open.
Compared with prior art, what the sticky cage pad of the present invention was used is nontoxic food grade plastic, does not contain harmful additive and various auxiliary agent in plastics.This invents maximum advantage is that material and wheaten food are not sticky, easy to clean, and only needing water to rush can wash away surface or inner filth.Service time is long, and through experiment, the cage pad of injection moulding was used after 12 months, and indeformable, not aging, significant change does not occur its mechanical properties.Relative gauze or straw mattress, this novel cage pad life cycle is long, and cost is low, convenience attractive in appearance.
