Description

Folding hard environment-protective composite
Technical field
The present invention relates to a kind of composite, more particularly, to a kind of folding hard environment-protective composite.
Background technology
In the 17th century, the U.S. starts using aerial cableway transmission bulk material；In the middle of the 19th century, the biography of various modern structures Band conveyer is sent to occur in succession.1868, there is belt conveyor conveyer in Britain；1887, occur in the U.S. Conveying worm；1905, there is steel belt conveyor in Switzerland；1906, there is inertia conveying in Britain and Germany Machine.Hereafter, conveyer belt conveyer is influenceed by machine-building, motor, chemical industry and metallurgical industry technological progress, constantly improve, Progressively by the transmission inside finishing department, develop into the material completed between enterprises, enterprise or even between city and carry, As materials conveying system mechanization and automate indispensable part.
PET resin (polyethylene terephthalate) is a kind of high performance engineering plastics, has preferable weatherability, chi Very little stability, wearability.With the development of China's plastics industry, food and packing business, its usage amount and application are all in urgency Acute extension.
The content of the invention
In order to overcome the shortcomings of the prior art, the invention provides a kind of flatness is good, folding, environmental protection folding it is hard Matter environment-friendly composite material.
A kind of folding hard environment-protective composite, the composite from bottom to top sequentially include counterdie, base fabric and facial mask, The counterdie is prepared by the raw material of following weight parts：100 parts of polyethylene terephthalate, 3~8 parts of colorant, facial mask It is prepared by the raw material of following weight parts：100 parts of polyethylene terephthalate, 3~8 parts of colorant；The base fabric is 800 ~1200D × 800~1200D polyester fiber grid cloths.
Preferably, the counterdie is prepared by the raw material of following weight parts：Polyethylene terephthalate 100 Part, 5 parts of colorant.
Preferably, the facial mask is prepared by the raw material of following weight parts：Polyethylene terephthalate 100 Part, 5 parts of colorant.
Preferably, the base fabric is 1000D × 1000D polyester fiber grid cloths.
Preferably, the composite is prepared by following step：One layer of slurry, heated baking are coated on facial mask After dry, semi-finished product are bonded with base fabric, then are dried after the side that this semi-finished product has reticulate pattern is coated with into one layer of slurry, through multiple Close the counterdie after wheel is dried with starching to be bonded, most cutting edge tentering is batched and obtained after cooling and shaping afterwards.
Preferably, the starching amount on facial mask is 15~22g/m2；During heating, drying, it is 70~120 to control temperature ℃；When being bonded with base fabric, it is 120~155 DEG C to control temperature, and loading pressure is 360~420N, and binding speed is 8~12m/ min。
Preferably, it is 15~22g/m that semi-finished product, which have the starching amount in the side of reticulate pattern,2；In drying course, control temperature Spend for 70~120 DEG C.
Preferably, when combined wheels are bonded with the counterdie after starching drying, temperature control is 160~190 DEG C, laminate pressure For 350~400N, fitting speed is 6~10m/min.PET material hardness is big, and calendering is not easy to shape, and out-of-flatness when being heated, is this In second of compound tense, the wheel gently fast ratio, then coordinate PET glue to bond base fabric of combined wheels is optimized, has reached very good Good fastness.
Preferably, during coating slurry, using 80 mesh gluing wheels.Because polyethylene terephthalate (PET) hardness is big, Anti-roll difficulty is big, therefore improves laminating apparatus, and using 80 mesh gluing wheels are used instead, is put forward the uniformity of gluing It is high.
Preferably, the composite is prepared by following step：
(1) one layer of slurry is coated on facial mask, after heated drying, semi-finished product are bonded with base fabric；Wherein, on facial mask Starching amount is 18g/m2；During heating, drying, it is 90 DEG C to control temperature；When being bonded with base fabric, it is 135 DEG C to control temperature, is glued Resultant pressure is 390N, binding speed 10m/min；
(2) dried after the side that this semi-finished product has reticulate pattern being coated with into one layer of slurry again；Wherein, semi-finished product have reticulate pattern Starching amount in the side is 18g/m2；In drying course, it is 90 DEG C to control temperature；
(3) counterdie after combined wheels are dried with starching is bonded, and most cutting edge tentering is batched and obtained after cooling and shaping afterwards；Its In, when combined wheels are bonded with the counterdie after starching drying, temperature control is 175 DEG C, laminate pressure 375N, and fitting speed is 8.5m/min。
The shortcomings that causing delamination because tortuous excessive instant invention overcomes hard PET material, have flatness it is good, it is stiffening, The advantages that resistance to tortuous, stripping is excellent；The present invention is with that after anti-slip rubber bonding, can be made the industrial conveyor-line of high intensity, carrying Ability is strong, and service life is permanent.
