Problems solved by technology

In the peel test of metal / adhesive / metal structure, the adhesive and metal interface cracked, and the peel force could not reach 10N / mm
Therefore, such adhesives are mostly used in non-structural materials such as flexible packaging, but cannot be used in fields that require high adhesion
[0007] In other words, in the prior art, if an adhesive containing a more active component is used, although the adhesive force is greater, the service life of the adhesive is reduced and the stability is poor. When the adhesive containing a more active component is not used, Adhesion can not meet the needs

Embodiment

[0031] The raw materials and intermediates used in the present invention are as follows.

[0032] Table 1 lists the raw materials used in the examples of the present invention. According to the basic type of material composition, it can be classified into LLDPE1, LLDPE2, LLDPE3, POE, HDPE, LDPE, PP and PS.

[0033] In Table 1, the materials under the same category only have different manufacturers and models, and their various parameters are basically similar. There is no need to distinguish them when they are used as general-purpose adhesives. In the following examples, if there is no special description, The raw materials used are the first item in each category as the experimental material (for example, the LLDPE1 in the embodiment, unless otherwise specified, refers to the Elite 5220G manufactured by DOW). In addition, its replacement with other products under the same category, or a combination of one or more of them, any combination thereof will not affect the final per...

Abstract

The invention aims to provide an adhesive which does not contain active ingredients (for example, EVA), and is high in stability, relatively long in service life and relatively great in binding force. The adhesive provided by the invention contains polyolefin-serial resin, a polystyrene-serial compound and acid modified polyethylene; the polyolefin-serial resin comprises more than any one of high density polyethylene, medium density polyethylene, low density polyethylene, linear low density polyethylene, a polyolefin elastomer and polypropylene; and the adhesive does not contain an ethylene-vinyl acetate copolymer. The adhesive provided by the invention has the beneficial effects of preventing use of necessary active ingredients (EVA) in a previous adhesive while keeping a sufficient binding force, so that the adhesive has a good binding property, an enough service life and excellent stability.

Description

technical field [0001] The present invention relates to an adhesive, and further relates to a polyolefin adhesive that does not contain polar polyolefin resin components such as EVA (ethylene-vinyl acetate copolymer). Background technique [0002] Currently based on polar polyolefins, such as ethylene-vinyl acetate copolymer and its modified intermediate, ethylene-vinyl alcohol copolymer and its modified intermediate, acrylic resin and its modified intermediate, cyanoacrylate and its Adhesives such as modified intermediates have been widely used. [0003] For example, US Pat. No. 5,516,583 discloses an adhesive containing EVA and styrene compounds as main components, specifically containing 50%-90% of EVA components and styrene homopolymer, and has good bonding performance. [0004] On this basis, U.S. Patent US20070071988A1 further discloses an adhesive containing EVA, styrene compounds and polyolefin compounds, specifically containing more than 10-30% of EVA. Although the...
