Abstract

The invention provides adhering resin for a high-barrier bottle and a preparation method thereof. The adhering resin is prepared from the following components of 15 to 30 parts of maleic anhydride-grafted linear low density polyethlyene master batch, 15 to 30 parts of high density polyethlyene, 15 to 30 parts of low density polyethlyene, 20 to 30 parts of POE (polyolefin elastomer), 5 to 10 partsof polylactic acid, 0.2 to 1 part of talcum powder, 0.2 to 0.5 part of antioxidant, 1 to 10 parts of plasticizer, and 2 to 6 parts of silane coupling agent. The invention further provides a preparation method of the adhering resin for the high-barrier bottle. The adhering resin for the high-barrier bottle and the preparation method have the advantages that the self color is transparent, the property is stable, and the number of crystal points is fewer; the adhering property of each layer of the prepared high-barrier property is high, the barrier property is strong, the inner surface and outersurface are smooth, the heat stability is good, and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesive resins, and relates to an adhesive resin for high-barrier bottles and a preparation method thereof. Background technique [0002] Due to the addition of ethylene-vinyl alcohol copolymer (EVOH) to act as a barrier layer, high-barrier bottles can effectively block gases, maintain product quality, and improve product shelf life. They are widely used in food, cosmetics, pharmaceuticals, and other packaging fields. Barrier bottles generally have two structural forms, one is a three-layer structure that is PE layer + adhesive resin + EVOH; the other is a five-layer structure that is PE layer + adhesive resin + EVOH + adhesive resin + PE layer. The barrier effect of the second structure is better than that of the first structure, because there are hydroxyl groups in the molecular structure of EVOH resin, which makes it hydrophilic and hygroscopic, and water absorption and hygroscopicity will reduce the ...
