Description

A kind of PVC inflatable boat material new technology

Technical field:

The present invention relates to a kind of manufacturing technique of inflatable dinghy material.

Background technology:

PVC, full name is Polyvinylchlorid, Main Ingredients and Appearance is a polyvinyl chloride, adds other one-tenth in addition and assigns to strengthen its heat resistance, toughness, ductility etc.The superiors of this skin covering of the surface are lacquers, and middle main component is a polyvinyl chloride, and orlop is a back of the body coating adhesive.

PVC can be divided into soft pvc and hard PVC.Wherein hard PVC accounts for 2/3 of market greatly, and soft pvc accounts for 1/3.Soft pvc generally is used for the top layer of floor, ceiling and leather, but owing to contain softener (this also is the difference of soft pvc and hard PVC) in the soft pvc, becomes fragile easily, is difficult for preserving, so its scope of application has been subjected to limitation.Hard PVC does not contain softener, so pliability is good, easy-formation, be difficult for crisp, nontoxic pollution-free, therefore the holding time is long, has very big development and application values.The essence of PVC is a kind of vacuum forming film, is used for the top layer packing of all kinds of panels, so the decorating film that is otherwise known as, attached glued membrane is applied to all conglomeraties such as building materials, packing, medicine.Wherein the proportion that accounts for of building material industry is 60% to the maximum, secondly is packaging industry, also has some other industries of using among a small circle.

The production technology of PVC is also uncomplicated, common production line generally is coated with machine by roller press, printing machine, the back of the body and cutting machine is formed, mainly be straight moving the stirring by roller press, roller bearing rotation and high hot rolling are produced thickness and only are the film of 0.3mm to 0.7mm, stamp pattern in the front of film when producing and by printing machine, be coated with machine by the back of the body and enclose one deck back of the body at the back side of film and be coated with.Shouldn't look down upon this layer back of the body and be coated with, it is an important assurance of PVC film high-quality performance.The back of the body is coated with by special material to be formed, and is a kind of high energy affinity agent, is coated with just because of this layer back of the body, and the PVC film could merge with medium airtight pane or other sheet material tightly, does not come unglued in 10 years even 15 years.And common veneer film is exactly the problem that comes off that can't solve film in greatest problem.Because a whole set of production process all at high temperature (the roll extrusion built-in temperature reaches 220 degree) is carried out, this just makes the PVC film have high light resistance and fire resistance, guarantees the high-quality of PVC film.Certainly, this is very high to the requirement of producing machine, and a common cover Production Line equipment manufacturing cost is about 3,000 9 hundred ten thousand marks, amounts to about 1.6 hundred million yuan of RMB.But then, the production technology of PVC film is but quite simple, and machine production is also very big, so see all sidedly, PVC is actual to be the product of a kind of low input, high yield.

At present the color of state, inside and outside general PVC inflatable boat material is single, can not satisfy the requirement of market for color and pattern, and the camouflage pattern material that Korea S a company produces, and puts on market to be subjected to very much the client parent bad.Korean company production camouflage pattern material technology is as follows: with base cloth two finishing coats, then one side stamps camouflage pattern therein, (Yin Jibu two sides coating weight increases, can only be with falling behind the screen printing technique impressing pattern, inevitable blooming), and then be coated with layer of transparent PVC, and its pattern is showed, reach purpose colour-fast, wear-resisting wiping.But because of complex process, cost is high, and the client is difficult to accept.

Summary of the invention:

The purpose of this invention is to provide a kind of PVC inflatable boat material new technology, it has, and technology is simple, production cost is low, pattern does well, non-fading advantage.In order to solve the existing problem of background technology, the present invention adopts following process technology scheme: 1, earlier base cloth is printed multicolour pattern; 2, printed base cloth reverse side is applied dark PVC; 3; Base cloth front surface coated transparent PVC can be finished.Red ink paste used for seals with base cloth among the present invention is printed between the coating of dark PVC; do not need to carry out the serigraphy of cost costliness; reduced production cost; because color has been subjected to the protection of two layers of material between two-layer PVC material; thereby be difficult for fading; make that also printing color is more wear-resisting, the pattern performance is more outstanding.Technology of the present invention is simple, utilize the process of lower cost can obtain high-quality product, and the product pattern that the present invention obtains does well, will never fade, rub resistance.Product of the present invention will promote the development of this industry.

The specific embodiment:

This specific embodiment adopts following process technology scheme: 1, earlier base cloth is printed multicolour pattern; 2, printed base cloth reverse side is applied dark PVC; 3; Base cloth front surface coated transparent PVC can be finished.This specific embodiment is printed on the red ink paste used for seals of base cloth between the coating of dark PVC; do not need to carry out the serigraphy of cost costliness; reduced production cost; since with common printed between two PVC coatings; color has been subjected to the protection of two layers of material between two-layer PVC material; thereby be difficult for fading, also make printing color more wear-resisting, the pattern performance is more outstanding.The technology of this specific embodiment is simple, utilize the process of lower cost can obtain high-quality product, and the product pattern that this specific embodiment obtains does well, will never fade, rub resistance.Product of the present invention will promote the development of this industry.

Difference between PVC film and the common stickup film is that common stickup film is directly to be attached on the surface of sheet material with glue at normal temperatures, and therefore through after one or two years, pad pasting just comes off easily.The PVC film then is that the vacuum film pressing machine of application specific presses down the surface that is attached to sheet material at the high temperature of 110 degree, so difficult drop-off.

Though the PVC film has good quality assurance, there is the people to say, PVC is chemical products after all, it is exactly less than natural material, does not get rid of toxicity and peculiar smell, also unavoidably environment is damaged.The fact is really not so, this is because the raw material of Germany production PVC film is through special refinement, noxious material is extract fully, so it is tasteless that PVC is a totally nontoxic, to human body skin or respiratory system without any stimulation, concerning the people of timber and paint allergy, it is very suitable using the furniture or the kitchen tools of PVC film packing for those.By using the PVC film to make decorating film, people just can use medium airtight pane, shaving board, glued board and fiberboard in large quantities, reduce and use amount of wood, thereby reduce forest and even environment damage.From this angle, the PVC film has been made very big contribution to the protection of ecological environment.
