Abstract
The utility model relates to a PVC plasticizer barrier layer, which comprises a PVC base material layer. The utility model is characterized in that a luminant oil layer on the surface of which an adhesive layer is covered is coated and covered on the upper surface of the PVC base material layer. By adopting the technical scheme, a middle transition layer is formed between the surface of the PVC base material containing a plasticizer and the adhesive. The transition layer has fine compatibility with the surface of stuck object and has great affinity with the adhesive. Meanwhile, the transition layer has the advantages of compact structure and high stability and can block the plasticizer from diffusing into the adhesive. Fine adherence can be formed between the base material and the adhesive. Therefore, aging resistant performance can be notably enhanced.
Description
Technical field
The utility model relates to a kind of barrier layer, can intercept the plasticizer of polyvinyl chloride (PVC) lining, makes adhesive on the PVC surface cementability be arranged, and significantly improves the ageing-resistant performance of adhesive.
Background technology
PUR is widely used in the bonding of various materials at present, with some substrate bondings in can be directly bonding, respond well, but the time with the PVC material adhesive, because the existence of a large amount of plasticizer greatly reduces the adhesive force between PVC and the adhesive among the PVC, and the ageing-resistant performance of adhesive also reduces greatly, so must select suitable adhesive for use and carry out necessary processing, just can overcome above-mentioned phenomenon.Generally be by mechanical grinding or solvent wash, and, be to adopt mechanical treatment that solvent wash has the suspicion of dissolving base material, does not reach expected effect for PVC.
Summary of the invention
The purpose of this utility model is that a kind of PVC of making base material and adhesive form the PVC plasticizer barrier layer of good bonding performance, thus the ageing-resistant performance of significantly improving.
A kind of PVC plasticizer barrier layer provided by the utility model comprises the PVC substrate layer, it is characterized in that: on the PVC substrate layer, be coated with bright oil reservoir, and at the surface coverage adhesive layer of bright oil reservoir.
Adopted above-mentioned technical solution, between PVC substrate surface that contains plasticizer and adhesive, form an intermediate layer, this transition zone both had good compatibility with the adherend surface, with adhesive bigger affinity is arranged again, while compact structure good stability, can intercept plasticizer and in adhesive, spread, make PVC base material and adhesive form good bonding, thereby significantly improve ageing-resistant performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model, it is PVC plasticizer barrier layer, in PVC substrate layer 1, contain a large amount of plasticizer, increased bonding difficulty, coating one deck bright stock 2 on PVC substrate layer 1, bright stock 2 is carried out ultraviolet curing to be handled, can intercept the plasticizer in the PVC substrate layer 1, and and adhesive good affinity is arranged, then at the surface coating adhesive layer 3 of bright stock 2, so adhesive layer 3 just and PVC substrate layer 1 formation good bonding, and the ageing-resistant performance of this assembly has also improved greatly, experimental results show that adhesive also has cementability after placing 7 days in 60 ℃ the baking oven.
