preparation example Construction

[0025] A preparation method of a foaming hot melt adhesive for household appliances, the preparation method comprising the steps of:

[0026] Step 1: Add the viscosity modifier into the reaction kettle equipped with electric stirring and heating devices, and keep the temperature of the viscosity modifier up to 140°C;

[0027] Step 2: When the viscosity regulator melts to half, start the electric stirring device in the reaction kettle and add polyolefin resin, and continue to stir at a constant temperature of 140°C until the polyolefin resin is evenly dispersed;

[0028] Step 3: After the polyolefin resin in Step 2 is uniformly dispersed, add ethylene-vinyl acetate copolymer under stirring, and slowly add antioxidant after the ethylene-vinyl acetate copolymer is completely melted under a constant temperature environment of 140°C;

[0029] Step 4: Stir continuously in a constant temperature environment of 140°C to mix the antioxidant evenly, then add the tackifying resin, start ...

Abstract

The invention belongs to a foamable hot melt adhesive for home appliances and a preparation method of the hot melt adhesive. The foamable hot melt adhesive is prepared from the following raw materials in parts by weight: 50-200 parts of viscosity modifiers, 100-400 parts of ethylene-vinyl acetate copolymers, 100-300 parts of polyolefine resins, 300-600 parts of tackifying resins and 5-10 parts of antioxidants. The foamable hot melt adhesive has the advantages of high adhesive ability, high and low temperature resistance and low consumption.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a foaming hot-melt adhesive for household appliances and a preparation method thereof. Background technique [0002] With the continuous development of hot melt adhesive technology, hot melt adhesive products are used more and more widely. As an important auxiliary material, hot melt adhesive mainly plays the role of bonding and sealing in application. Hot melt adhesives are mainly used in automation equipment due to their advantages of cleanliness, pollution-free, non-toxic, short open time, and fast curing speed. [0003] Hot melt adhesive has fast curing speed and strong bonding performance, and is widely used in packaging, book binding, bonding and sealing of home appliances, and automatic and rapid production lines in the tobacco industry. In addition, it also has a good sealing and insulating effect on some railway signal cables. [0004] EVA hot-m...
