[0030] Its preparation method comprises the following steps:
[0031] Step 1: Put PC resin and ABS resin into a speed mixer, and stir at a speed of 900-1100r / min for 20-30min; then add light storage powder and various additives, and stir at a speed of 900-1100r / min for 20-30min ; Among them, before adding the light storage powder, first mix it with the main antioxidant in a ceramic container at a speed of 40-50r / min, stir it for 5-10min, and then add it to the pre-stirred resin
[0032] Step 2, sending the stirred raw materials into a granulator for granulation to obtain hot-melt rubber granules;
[0033] Step 3, transfer the hot-melt rubber particles into a tape castingmachine, and cast them into a film to obtain the hot-melt adhesive film with light storage effect.
[0034] Wherein, the preparation method of light storage powder specifically comprises the following steps:
[0039] A hot-melt adhesive film with light storage effect is composed of the following raw materials in parts by weight: 60 parts of PC resin, 30 parts of ABS resin, 10 parts of light storage powder, and 0.2 part of auxiliary agent.
[0040] The auxiliary agent is composed of anti-UV agent, primary antioxidant and secondary antioxidant in a mass ratio of 2:1:1.
[0041] The main antioxidant is made up of the following raw materials by weight: 70 parts of antioxidant 168, 20 parts of stearic acidamide, 15 parts of PE wax, 40 parts of ethyl acetate, 10 parts of organotin, 10 parts of Phosphite, 30 parts of fumed silica, 20 parts of bentonite.
[0042] Secondary antioxidant is made up of the raw material of following parts by weight: 40 parts of antioxidant 1076, 30 parts of antioxidant DNP, 20 parts of silanecoupling agent, 40 parts of zincstearate, 10 parts of paraffin, 30 parts Parts of alkyl modified organosiloxane, 15 parts of epoxysoybean oil.

Abstract
The invention relates to a hot meltadhesive film with a light storage effect. The hot meltadhesive film is prepared from the following raw materials: PC resin, ABS resin, light-storing powder and an auxiliary agent; the auxiliary agent is composed of an anti-UV agent, a main antioxidant and an auxiliary antioxidant according to the mass ratio of 2: 1: 1; the main antioxidant is prepared from the following raw materials: an antioxidant 168, octadecanamide, PE wax, ethyl acetate, organic tin, phosphite ester, fumed silica and bentonite; by adding the light storagepowder, the hot meltadhesive film subjected to tape casting also has a light storage effect besides the adhesive property of a common hot melt adhesive film and can be suitable for more occasions, and the practicability of the hot melt adhesive film is improved; meanwhile, the specific composition of the main antioxidant is limited, and the PE wax is matched with the fumed silica and the bentonite to ensure that the light storage powder can be stably dispersed in the resin and cannot settle, so that the hot melt adhesive film which is finally subjected to tape casting can uniformly emit light; the organic tin is matched with the phosphite ester, so that the formation of the light storage powder in the preparation and use processes can be stabilized, and the light reflecting effect of the hot melt adhesive film is ensured.
Description
technical field [0001] The invention belongs to the field of hot-melt adhesive films, in particular to a hot-melt adhesive film with light storage effect. Background technique [0002] Multifunctional, low energy consumption, and environmental protection are the main themes in today's new situation. Although the materials in our hot melt adhesive film industry are environmentally friendly, many adhesive films are produced by coating methods, and the adhesive film needs to be matched with a layer of release material. To support, and the release material is often silicone oil paper. Even if some manufacturers claim to use hot-melt adhesive bare film, the products on the market do not have release paper attached, but they are basically produced by coating method, and the paper is rewound separately and reused later. Even though the release paper can be used three times, reducing the demand for release paper, a coatingmachine can still produce about 250 tons of waste paper pol...
