Abstract

The invention belongs to a hot melt adhesive and a preparation process thereof. The hot melt adhesive is composed of naphthenic oil, white oil, EVA (Ethyleno Vinyl Acetale), APAO (Amorphous Poly Alpha Olefin), wax, rosin modified resin, petroleum resin, an antioxidant and an anti-aging agent. The preparation process comprises the following steps: preparing materials at a formula ratio; checking to confirm that no foreign matter exists in a reaction kettle, and starting a switch to heat conductive oil; and putting the naphthenic oil, the white oil, the wax, the antioxidant, the anti-aging agent and the like, heating for 25-35 minutes, putting APAO, EVA and the like after the temperature is increased to 65-75 DEG C, introducing nitrogen in the reaction kettle, heating and stirring for 1-3 hours, putting the rosin modified resin and the petroleum resin after the materials are completely melted, and vacuumizing and stirring until a colloid is uniform and free from bubbles so as to obtain the adhesive. The hot melt adhesive is mainly applied to adhering the materials, such as paper, artworks and coated films; and the hot melt adhesive prepared by the invention is high in adhesive force, high in drying speed, low in energy consumption, good in thermal stability, aging resistant and acid and alkali resistant, and is applied to automatic flow line producing and packaging requirements.

Description

Technical field [0001] The invention relates to an adhesive, in particular to a hot melt adhesive and a preparation process thereof. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical characteristics remain unchanged, and it is non-toxic and tasteless. It is an environmentally friendly chemical product. Hot melt adhesive has been used in many domestic industries. With a wide range of applications, hot melt adhesives have broad prospects in the domestic and foreign markets, and hot melt adhesives are increasingly needed in various industries, and they are widely used in refrigerators, cables, tobacco, food, dairy and other industries. Compared with paper, non-woven fabrics, lining, leather and other products, the hot melt adhesives currently on the market have a higher price and cost, and they are not effective in high-temperature environments, have poor t...
