Description

A kind of polyvinyl chloride diaphragm

Technical field

The utility model is related to a kind of automobile eyeglass diaphragm, more particularly to a kind of polyvinyl chloride diaphragm.

Background technology

Mechanization is to manufacture the trend that industry develops with automation, especially in automobile manufacture industry field, manipulator The application of arm is extremely widespread, while part manufacture different during automobile is made can all use substantial amounts of diaphragm conduct Protection is made, but because mechanical arm does not possess manually-operated subjective initiative and flexibility in operation, so, Comparatively speaking, its quality stability to diaphragm require it is high, automobile plastic eyeglass in cutting process, without the need for being manually Diaphragm is fitted in by glass lens surface with machine automatically, shape cutting is then carried out and is then polished edge trimming, processing procedure After end diaphragm is peeled off using automatic arm, it is different from the past by artificial, manually can according to circumstances flexible modulation hand-power, Fixed force value and stripping force value set by automatic mechanical arm is all fixed, so if diaphragm unstable properties cannot Matching mechanical arm makes it smoothly fixed or peels off diaphragm, then just easily impact process rate is reduced or speed of production cannot Improve.

Utility model content

The utility model aims to provide a kind of polyvinyl chloride diaphragm.

To realize above-mentioned technical purpose, the utility model is employed the following technical solutions, a kind of polyvinyl chloride diaphragm, including Base material and ground, the base material specifically polyvinyl chloride film, its thickness is 80um ± 8um, inside adds plasticiser, the polyvinyl chloride The two-layer up and down of film is adhesive force coating, and the adhesive force coating specifically forms polyurethane attachment using polyurethane silane coupling agent Power coating, wherein being stained with adhesive layer below the adhesive force coating of lower floor, the adhesive layer is acrylic acid acrylic gluing Layer, is stained with Ge Laxin release liners below the adhesive layer.

Preferably, the solid content of described polyurethane silane coupling agent is 20 ± 2%, viscosity is 500 ± 100cps.

Preferably, the grammes per square metre of described Ge Laxin release liners is 80 ± 10g, off-type force 5-15g/in2, remaining rate >= 80%。

From polyvinyl chloride film as base material, general automobile plastic eyeglass is all carried the technical solution of the utility model Radian, not tilt in and procedure for producing after fitting completely docile with surface and edge and not peel off, film it is docile Property require to need to improve, pay the utmost attention to low density polyethylene (LDPE) and the film of polyvinyl chloride two in selection, low density polyethylene (LDPE) because It is laxer for molecular structure and crystalline solid is few so pliability is excellent, and polyvinyl chloride is because interior addition plasticiser softens film, Former film is likely to result in thermal contraction in view of temperature requirement in coating production and deformation, we compared for main two performances, The softening point of polyethylene is about 80 DEG C, and fusing point is 110 DEG C, and the softening point of polyvinyl chloride is 100 DEG C, and fusing point is 190 DEG C, polyethylene Contraction distortion is easier at high temperature, so final selection is polyvinyl chloride, furthermore, the running of cooperative mechanical arm, polychlorostyrene second Alkene compares polyethylene deflection and preferably fits and peel off compared with ratio of greater inequality, and in order to coordinate automated production, and diaphragm sticks together stability Must be high, it is that stability is sticked together in raising, the acrylic acid acryl adhesive that we select is against the spy for being used to have in general pressure sensitive adhesive Property（The laminating time is more long, and adhesion is higher）, that focuses on that raising initial stage adhesion makes that diaphragm can be submissive is docile with arc The lens surface of degree, reducing follow-up adhesion makes diaphragm not pasted the follow-up machine of dynamics enhancing impact because the laminating time increases it Arm peels off smooth degree during diaphragm, and to avoid polyvinyl chloride film from being heated in procedure for producing contraction distortion is caused, we Take transfer coated production technology, but because polyvinyl chloride belongs to low polarity material, transfer coating technology of such as arranging in pairs or groups again, can cause with Glue-line layering cannot be combined, therefore we select polyurethane silane coupling agent as polyvinyl chloride film and acrylic acid acryl gluing The intermediate medium of agent solving, the attachment of reinforced polyvinyl chloride film and acrylic acid acryl, and selecting and polyvinyl chloride material The polyurethane silane coupling agent for matching can also solve the problems, such as the low-surface-energy of polyvinyl chloride film material, one in polyvinyl chloride film As can add plasticiser the pliability and elasticity for increasing its material is fetched with spacer molecule chain, but plasticiser belongs to oiliness, reduces Material surface polarity makes its surface be not easy attachment, can make the polyvinyl chloride surface can be with mechanical arm using polyurethane silane coupling agent The nonpolar metal alloy injected combines and smoothly peels off diaphragm and abandons, and metal alloy belongs to non-polar material, no Easily then, need to be by adhesive force paint as medium enhancing and the throwing anchor of polyvinyl chloride, and the utility model is using release liners Non- mould release membrance is because the die cuttability of mould release membrance not as release liners as ground, and the die cuttability of general film release liners is not Such as high-density Ge Laxin paper, therefore Ge Laxin paper is selected as the final collocation of product.
