Integrated processing device of in-plant production of surface-coated and modified BOPP (Biaxially Oriented Polypropylene) synthetic paper

Abstract

The invention relates to an integrated processing device of in-plant production of a surface-coated and modified BOPP (Biaxially Oriented Polypropylene) synthetic paper. The integrated processing device comprises a BOPP synthetic paper forming machine, a stripping device and at least one surface coating machine, wherein the BOPP synthetic paper forming machine is used for machining compositions mainly comprising polypropylene to finish primary blank synthetic paper and reeling the primary-blank synthetic paper to a long paper roll with the width of eight meters; then the stripping device is used for cutting the long paper roll with the width of eight meters into multiple segments of short paper rolls by a cutting tool; and the at least one surface coating machine is used for carrying out surface coating and modifying on stripped short paper roll primary blanks to form a paper surface layer having multiple superfine air hole volumes and an air hole series connection degree similar to the natural paper. According to the integrative processing device of the in-plant production of the surface-coated and modified BOPP synthetic paper, the in-plant integrative production is realized, the cultural paper or the packaging paper can be produced with the lowest cost and production process, and the target of protecting environmental resources is accorded.

Description

technical field [0001] The present invention relates to a kind of integrated process equipment for the production of BOPP synthetic paper modified by surface coating, in particular to an 8-meter (M) wide blank completed by a biaxially stretched polypropylene (BOPP) synthetic paper forming machine Synthetic paper is first cut into short paper rolls with a width of less than 2 meters by slitting equipment, and then sent to more than one surface coating machine to modify the surface to form a paper surface layer like natural paper. To achieve the goal of consistent production. Background technique [0002] Human civilization continues to progress rapidly, so the demand for paper continues to increase, but pulp is needed to make paper, so trees are constantly being cut down, which greatly affects the earth's environment and ecology, and even suffers counterattacks from nature. [0003] As a result, some people in the industry began to develop polyolefin synthetic paper to repla...

[0004] However, according to the investigation, the synthetic paper obtained in the above-mentioned Japanese patent case has the advantages of rigidity and good mechanical strength, but the amount of fine pores on the paper surface and the degree of connection of pores are far from the natural paper, which makes the printing process After that, it is not easy to dry, and the ink must be dried in other ways, which will increase the time and cost of printing operations virtually, which is why it is not widely applicable to cultural paper

[0005] In addition, another existing synthetic paper on the market is mainly made of three-layer or five-layer co-extruded biaxially stretched polypropylene. The production equipment is relatively complicated and costly, and the synthetic paper formed by it has a wide width It is 8 meters (M), which is very inconvenient for the subsequent process of reprocessing on the surface of synthetic paper

The general processing situation is to send its 8-meter-wide and long paper roll to the cutting factory by truck, cut it into multiple short paper rolls, and then send it to the predetermined surface treatment factory by truck; therefore, regardless of manpower, handling and In terms of quality, both are affected, and the cost will only increase, so that the pearlescent synthetic paper is still not popular, so there is still room for improvement
