Embodiment 1

[0018] The preparation method is as follows:

[0019] Put metallocene catalyzed polypropylene wax PP2602, maleic anhydride modified polypropylene wax PPMA7452 tackifying resin FP-125, TR7115, first antioxidant 1010, and first antioxidant 168 into an electric heating reaction furnace for heating and heating The temperature is controlled at 180°C, and the stirring is started. After it is completely melted, add the first amorphous polyolefin APAO792, the second amorphous polyolefin APAO888, the third amorphous polyolefin APAO408 and low-density polyethylene LDPE 955. After stirring for 30 minutes, Turn on the vacuum, the vacuum pressure is less than -0.9MPa, and continue to stir for 60 minutes to ensure that the material is melted evenly.

[0020]

[0021] The amorphous polyolefin is an ethylene-propylene copolymer, and the comprehensive preferred proportion of APAO 792, APAO888, and APAO 408 is 45-55 parts (by weight) based on the characteristics of softening point, material ...

Abstract

The invention provides a polyolefin hot melt glue composition for woodworking precoating and edge sealing. Glue is put on an edge sealing strip in a coating mode through glue scraping or glue rolling for rapid surface dry winding, the pre-coated edge sealing strip is used for edge sealing through professional equipment, the glue use amount is small, glue lines can be effectively reduced, weather fastness is improved, and especially high heat resistance is achieved. The polyolefin hot melt glue composition is characterized by being prepared from, by weight, 45-55 parts of amorphous polyolefin,10-20 parts of low density polyethylene, 20-30 parts of tackifying resin, 2-5 parts of metallocene catalytic polypropylene wax, 3-5 parts of maleic anhydride modified polypropylene wax and 0.5-1 part of antioxidant. The invention further provides a preparation method of the polyolefin hot melt glue composition for woodworking precoating and edge sealing.

Description

technical field [0001] The invention relates to the technical field of polyolefin hot-melt adhesives, in particular to a polyolefin hot-melt adhesive composition for woodworking pre-coating and edge sealing and a preparation method thereof. Background technique [0002] Polyolefin hot-melt adhesive is a new type of adhesive, which is solid at room temperature and melts into liquid when heated to a certain temperature. It can be used by spraying, rolling and scraping, and becomes solid when cooled to room temperature. After melting and gluing, give a certain pressure, cool and solidify to produce a good bonding effect. It does not contain any solvent, no pollution, simple production process, easy to use, and has a wide range of uses. It can be used in sanitary materials, packaging, book binding, wood, and automobile industries. etc. [0003] Nowadays, EVA hot melt adhesive is generally used for woodworking edge banding in the market. The process generally adopts rolling glue...
