A kind of pe/pp two-color sand skin pattern hose and preparation method thereof

Abstract

The invention provides a PE / PP two-color nubuck leather pattern hose and a production method thereof. The PE / PP two-color nubuck leather pattern hose is made from an inner layer plastic raw material and an outer layer plastic material; the inner layer plastic material comprises, by weight, 30-100 parts of low-density polyethylene, 10-50 parts of metallocene and 1-8 parts of a dark color master batch; and the outer plastic material comprises, by weight, 5-35 parts of high-density polyethylene, 10-50 parts of metallocene, 30-70 parts of polypropylene and 1-15 parts of a light color master batch.The production method comprises the following steps: preparation of raw materials; production of the PE / PP nubuck leather pattern hose; vacuum cooling; air-cooling box cooling; and cutting and storing. The method allows various single-color and two-color plastic hoses with a nubuck leather pattern, a bark pattern and a leopard pattern to be produced without adding a new process, and the producedPE / PP two-color nubuck leather pattern hose makes printed ink be still firm and not shed without coating oiling before printing.

Description

technical field [0001] The invention belongs to the technical field of PE hoses or PP hoses, in particular to a PE / PP two-color sand leather hose and a preparation method thereof. Background technique [0002] At present, the preparation of outer packaging PE plastic hoses for daily chemical products such as facial cleanser, hair conditioner, body lotion, shower gel, BB cream, sunscreen, hand cream, etc., uses twin-screw co-extruded PE plastic hoses. The tube drawing machine uses low-density polyethylene (LDPE), high-density polyethylene (HDPE), and metallocene (LLDPE) in a fixed ratio. The process parameters such as temperature, pressure, and speed have not changed. The surface of the PE hose prepared by this traditional technology is too smooth. In order to facilitate printing of corresponding patterns or corresponding product information on the PE hose in the later stage, the prepared PE hose must be coated with oil printing color in the subsequent printing process. firm...

Problems solved by technology

[0002] At present, the preparation of outer packaging PE plastic hoses for daily chemical products such as facial cleanser, hair conditioner, body lotion, shower gel, BB cream, sunscreen, hand cream, etc., uses twin-screw co-extruded PE plastic hoses. The tube drawing machine uses low-density polyethylene (LDPE), high-density polyethylene (HDPE), and metallocene (LLDPE) in a fixed ratio. The process parameters such as temperature, pressure, and speed have not changed. The surface of the PE hose prepared by this traditional technology is too smooth. In order to facilitate printing of corresponding patterns or corresponding product information on the PE hose in the later stage, the prepared PE hose must be coated with oil printing color in the subsequent printing process. firm

[0003] In addition, the traditional technology can only produce single-color and smooth PE hoses. If you want to prepare various single-color and two-color plastic hoses such as sand-pit, bark, and leopard prints, you must use single-color PE soft hoses. Printing and painting on the basis of tubes increase the production process and increase the cost, and the produced sand leather pattern is easy to peel off the paint, and there is no concave-convex layering and three-dimensional effect

[0004] In response to the current market demand and the international competitive environment, people pay more and more attention to their own image and personal care. The hoses produced by the existing technology are too traditional and single, which can no longer meet the diversified and individualized needs of the market, and do not have Competitive advantages in the market, especially the inability to satisfy the modern post-90s and post-00s pursuit of highly personalized products and packaging
