A radiant cross-linking fire-retardant and heat-shrinkage indicating double pipe and its production are disclosed. The process is carried out by taking ethane-vinyl acetate multi-polymer, ethane-ethyl acrylate multi-polymer, ethylene-propylene rubber, fire-retardant decabromodiphenyl ethane, antimonous oxide, surface-activated superfine-magnesium hydrate and auxiliary as raw material, mill granulating, extrude forming, radiant cross-linking, expand sizing, and finish treating. It has better weather-resisting, high and low-temperature-resisting, anti-corrosive and antibacterial performances and long-period storage. It can be used for military industry, aviation and aerospace, civil high-terminal electronic equipment and cable.

The invention belongs to the technical field of packaging materials, particularly relates to a coating film and discloses a BOPE (biaxially-oriented polypropylene) coating composite film, which is characterized by comprising a function layer, a core layer and an auxiliary layer. The core layer is positioned between the function layer and the auxiliary function layer, the function layer, the core layer and the auxiliary function layer are integrated by means of biaxially stretching after being in coextrusion, the mass percent of the function layer ranges from 1% to 8%, the mass percent of the core layer ranges from 91% to 98%, the mass percent of the auxiliary function layer ranges from 1% to 5%, raw materials of the function layer include, by mass percent, 55% of acetic ether, 10% of C9 hydrogenated petroleum resin, 18% of metallocene polyethylene, 13% of polyvinyl alcohol, 2% of sodium hydroxide, 1% of antioxidant and 1% of dispersing agent, raw materials of the core layer include, by mass percent, 97.95% of linear polyethylene, 0.05% of nucleating agent and 2% of antioxidant 1076, components of the auxiliary function layer include, by mass percent, from 97 to 98% of metallocene polyethylene, from 1 to 2% of SiO2 and 1% of antioxidant 1076. The BOPE coating composite film has the advantages of fine printing performances and wiping resistance.

The invention belongs to the technical field of label materials, and particularly relates to a coating membrane of labels for personal care products, beer, cosmetics, beverages, electronic products, toys and the like. A BOPP (biaxially-oriented polypropylene) extrusion coating membrane is characterized by comprising a functional layer, a core layer and a secondary functional layer; the core layer is positioned between the functional layer and the secondary functional layer; the functional layer, the core layer and the secondary functional layer are subjected to coextrusion, then are stretched bidirectionally, so as to form an integrated body; materials for preparing the functional layer, the core layer and the secondary functional layer respectively account for 5-20%of the total weight, 60-90%of the total weight, and 5-20% of the total weight; the materials for preparing the functional layer are prepared by mixing acrylic-modified polyethylene, blocked copolymerized polypropylene, C9 hydrogenated petroleum resin, an antioxidant and a dispersion agent; the acrylic modified polyethylene accounts for 30-60% of the total weight, the blocked copolymerized polypropylene accounts for 30-45% of the total weight, the C9 hydrogenated petroleum resin accounts for 7-20% of the total weight, the antioxidant accounts for1-3% of the total weight and the dispersion agent accounts for1-2%of the total weight. The BOPP extrusion coating membrane provided by the invention has the characteristics of low cost, good printing firmness and good wiping resistance.

The invention belongs to the technical field of packing materials, and particularly relates to a BOPP (biaxially-oriented polypropylene) coating matt mould, which is characterized in that the BOPP coating matt mould comprises a functional layer, a core layer and a secondary functional layer, the core layer is positioned between the functional layer and the secondary functional layer, the functional layer, the core layer and the secondary functional layer are coextruded and then bidirectionally stretched into a whole, the weight percents of the functional layer, the core layer and the secondary functional layer are 1-8%, 91-98% and 1-5% respectively, raw materials of the functional layer include, in weight percent, 55% of acetic ether, 10% of C9 hydrogenated petroleum resin, 18% of polypropylene, 13% of polyvinyl alcohol, 2% of sodium hydroxide, 1% of antioxidant and 1% of dispersing agent, raw materials of the core layer include, in weight percent, 92% of polypropylene, 5% of stiffening agent and 3% of antistatic agent, and raw materials of the secondary functional layer include, in weight percent, 48% of high-density polyethylene, 48% of polypropylene, 3% of SiO2 and 1% of antioxidant. The BOPP coating matt mould has a fine printing performance and has an extinction function.

The invention relates to the technical field of an LED (Light Emitting Diode) long strip light, in particular to flexible ink for a white cover film of an LED soft light strip plate and a preparation method of the flexible ink. The flexible ink for the white cover film of the LED soft light strip plate is prepared from the following raw materials in percentage by mass: 30-70 percent of thermosetting resin, 2-10 percent of curing agent, 5-30 percent of diluting agent and 10-40 percent of filler. According to the ink and the preparation method thereof, excellent bend resistance performance can be achieved, the wiping resistance performance and the high temperature resistance performance are better, the ink is difficult to crack and yellow under a high temperature condition, and the requirements of a reflow soldering process of the light strip plate are met.
