Problems solved by technology

However, conventional hot melt adhesives are currently used to bond bamboo fibers and non-woven fabrics, which cannot meet the requirements of product design and production.
[0005] In addition, in product design, difficult-to-bond substrates such as silk, hot-air cloth, smooth non-woven fabric, cotton fiber, bamboo fiber, and viscose fiber will be combined with a variety of different fabrics for different parts of the product. The use of different hot melt adhesives for fabric compounding will greatly increase the complexity of production and production costs. A hot melt adhesive is required to meet the compounding requirements of different difficult-to-bond substrates and different fabrics

preparation example Construction

[0039] The second object of the present invention is achieved by the following technical solutions: a method for preparing hot melt adhesive for difficult-to-bond substrates, comprising the following steps:

[0040] (1) Add part of the naphthenic oil of formula quantity and the antioxidant of formula quantity in kneader, and heat up;

[0041] (2) Add the formula amount of styrene-based elastomer and stir. After the mixed system is melted, add the formula amount of styrene-butadiene rubber, continue to stir and melt; after the mixed system is melted, add the formula amount of polyolefin elastomer After stirring and mixing evenly, add the amount of tackifying resin in the formula, and stir evenly for 20 minutes;

[0042] (3) Put in the remaining naphthenic oil and ultraviolet absorber, stir evenly for 20 minutes, vacuumize to remove air bubbles, discharge the material, cool to room temperature, and obtain a hot-melt adhesive for difficult-to-stick substrates.

[0043] As a furt...

Abstract

The invention discloses a hot melt adhesive for a difficult-to-stick base material and a preparation method of the hot melt adhesive. The hot melt adhesive for the difficult-to-stick base material isprepared from the following components in parts by weight: 10 to 30 parts of naphthenic oil, 10 to 30 parts of styrene elastomer, 7 to 20 parts of solution polymerized styrene-butadiene rubber, 3 to 20 parts of polyolefin elastomer, 15 to 70 parts of tackifying resin, 0.35 to 3 parts of an antioxidant and 0.2 to 1 part of an ultraviolet light absorber. The hot melt adhesive disclosed by the invention can be used for well bonding difficult-to-adhere base materials so as to meet the adhesion requirements of different difficult-to-adhere fabrics, so manufacturers of sanitary material products such as paper diapers and sanitary towels can be provided with more options for high-quality fabrics, such as silk fabrics, hot through-air fabrics, smooth non-woven fabrics, cotton fiber fabrics, bamboofiber fabrics and viscose fabrics.

Description

technical field [0001] The invention relates to a hot-melt adhesive technology, in particular to a hot-melt adhesive for a difficult-to-bond base material and a preparation method thereof. Background technique [0002] At present, manufacturers of diapers, sanitary napkins and pet sanitary pads are looking for more and better fabrics to be used in disposable sanitary products; at the same time, more requirements are placed on hot melt adhesives for fabric bonding. At present, silk fabrics, hot air cloths, smooth non-woven fabrics, cotton fiber fabrics, bamboo fiber fabrics, viscose fiber fabrics, etc. are all high-quality fabrics that can be applied to diapers and sanitary napkins, but due to these silk fabrics, hot air cloths, etc. , smooth non-woven fabrics, cotton fiber fabrics, bamboo fiber fabrics, and viscose fiber fabrics, which have a high degree of fibrosis and relatively fluffy volume, are difficult to bond with conventional hot melt adhesives. Currently, there is ...
