Description
(1) technical field
The present invention relates to rubber technical field, more particularly to a kind of conveyer belt of accessible food.
(2) background technology
Using conventionally produced, rubber conjunction with natural rubber and commonly more than sizing material used in current domestic food conveyer belt
Based on rubber.Due to rubber loss of properties on aging used, thus a variety of age resistor need to be added to strengthen the resistance to ag(e)ing of sizing material
Can, and sulfur cross-linking system is generally used, need sulphur and a variety of chemical assistants to complete vulcanization, various chemical industry are former needed for production
Material often up to ten it is several more than, and in sizing material contain more sulphur.Due to the pair generated in complicated component, and heating sulfidation
Product is more, and the conveyer belt that final production comes out is also easy to produce smell, also contains toxic chemical substance, thus the food for conveying
Wholesomeness is substantially reduced, and vulcanizate smell and hygienic requirements are not ideal enough.
(3) content of the invention
The present invention in order to make up the deficiencies in the prior art there is provided a kind of composition it is simple, without using age resistor, vulcanized
Accessory substance produced by journey greatly reduces, the conveyer belt for the accessible food that wholesomeness is significantly improved.
The present invention is achieved through the following technical solutions：
A kind of conveyer belt of accessible food, including polyester fiber layer of cloth, are coated with the outside of polyester fiber layer of cloth and cover
Lid glue, the rubber cover is prepared from the following raw materials in parts by weight：
90-110 parts of ethylene propylene diene rubber, 20-40 parts of white carbon, 20-40 parts of nano-calcium carbonate, 1-2 parts of 3M vulcanizing agents, oxygen
Change 3-5 parts of zinc, 4-6 parts of paraffin oil；
The preparation method of the conveyer belt of the accessible food, comprises the following steps：
Ethylene propylene diene rubber is kneaded 3 minutes in banbury at 50 DEG C, white carbon, nano-calcium carbonate, 3M is then added
Vulcanizing agent, zinc oxide and paraffin oil kneaded 15 minutes at 120 DEG C after rubber cover, then rubber cover uniformly wrapped by calender
The outside of polyester fiber layer of cloth is overlayed on, the conveyer belt of the accessible food is produced.
The conveyer belt of the accessible food, including polyester fiber layer of cloth, are coated with covering on the outside of polyester fiber layer of cloth
Glue, the rubber cover is prepared from the following raw materials in parts by weight：
100 parts of ethylene propylene diene rubber, 30 parts of white carbon, 30 parts of nano-calcium carbonate, 1.5 parts of 3M vulcanizing agents, 4 parts of zinc oxide,
5 parts of paraffin oil；
The preparation method of the conveyer belt of the accessible food, comprises the following steps：
Ethylene propylene diene rubber is kneaded 3 minutes in banbury at 50 DEG C, white carbon, nano-calcium carbonate, 3M is then added
Vulcanizing agent, zinc oxide and paraffin oil kneaded 15 minutes at 120 DEG C after rubber cover, then rubber cover uniformly wrapped by calender
The outside of polyester fiber layer of cloth is overlayed on, the conveyer belt of the accessible food is produced.
The ageing-resistant performance such as the resistance to ozone of ethylene propylene diene rubber, heat-resisting, weather-proof is excellent, can be widely used for automobile component, building
With fields such as waterproof material, electric wire and cable jacket, heat-resistant rubber hose, adhesive tape, automotive sealants；
White carbon is used in colorful rubber product carries out reinforcement with alternative carbon black, meets the need of white or translucent product
Will.White carbon has superpower adhesion, tear-proof and heat-resisting ageing resistace simultaneously, so also may be used in black rubber product
Part carbon black is substituted, to obtain high-quality rubber, such as off-the-highway tire, engineering tyre, radial-ply tyre；
Nano-calcium carbonate has good compatibility with rubber, with reinforcement, filling, toning, improvement processing skill and product
Performance, can be such that rubber easily kneads, easily disperse, colloid is soft after mixing, and rubber surface is smooth；Extensibility, the anti-tensile of product can be made
Intensity, tearing strength etc. have the raising of essence；The rubber of sodium rice calcium carbonate is added, its vulcanizate rises long rate, tear fracture performance, compression
Deformation and the energy of resistance to tropism, all than adding the high of general calcium carbonate.It can not only be used alone as reinforcement and filler material, Er Qieke
Used cooperatively according to production requirement with other inserts, such as：Carbon black, white carbon, fine particle calcium carbonate coarse whiting, titanium dioxide, clay etc., reach benefit
By force, fill, mix colours, improving processing technology, improving product properties and reduce the purpose of gum content；
Zinc oxide is mainly used in rubber industry and makees reinforcing agent and activating agent, also serves as the colouring agent and filler of white size,
So that rubber has good corrosion resistance, tear resistance and elasticity；
3M vulcanizing agents are particularly suitable for transparent article vulcanization, and such as glass rubber sole, transparency is peroxide cure body
One of best kind in system, curingprocess rate is fast, and compression set is small, it is adaptable to EP rubbers, nitrile rubber, silicon rubber,
Chlorosulfonated polyethylene, polyurethane rubber vulcanization, available for requiring nontoxic, or in terms of food-grade, pharmaceutical grade product；
Paraffin oil can be used for improving rubber ageing resistance and increase pliability.
The beneficial effect of the conveyer belt of the accessible food of the present invention is：Rubber used, which is used, has ageing-resistant performance excellent
Ethylene propylene diene rubber, without using age resistor, sizing material has prominent ageing-resistant performance, and vulcanizing agent is made from 3M vulcanizing agents, removes
The compositions such as sulphur, accelerator, vulcanization aid, make formula components extremely simple, chemical material species used reduce 60% with
On.Because composition is simple, the accessory substance produced by sulfidation is also greatly reduced, while contained lower-molecular substance in sizing material
Corresponding to reduce, vulcanizate smell and sanitary condition are significantly improved, and wholesomeness is greatly improved；Final obtained conveying
With safe and reliable, contact not colored when vegetables, medicinal material etc., clean feel and the sense of security are higher, and bone is done by polyester fiber layer of cloth
Rack-layer, the features such as polyester fiber cloth has nontoxic, tasteless, dimensionally stable, rubber cover is nontoxic, tasteless, anti-aging, tear-resistant, no
Easy cooperating microorganisms, can be widely used for conveying vegetables, food and daily necessities etc..
