Embodiment 1

[0023] Naphthenic oil 20KG; SBC (thermoplastic styrene-butadiene rubber) 25KG; hydrogenated rosin resin 35KG; hydrogenated petroleum resin 15KG; pure C9 hydrogenated petroleum resin 5KG; antioxidant 1010 0.6KG / 100KG.

[0024] Process flow:

[0025] First put naphthenic oil and antioxidant 1010 into the 300L reaction kettle A1 filled with nitrogen through the gear pump (the air compressor 5 pressurizes the nitrogen in the nitrogen bottle to the reaction kettle A1) to heat, turn on the stirring motor, and gradually adjust the speed to 15~25r / min, after the temperature rises to 70~80°C, suck half of the SBC through the vacuum feeding device 3, turn on the stirring motor at a low level during the feeding process, and stir the materials evenly. Then gradually adjust the motor speed to 120r / min. After the temperature of the material rises to 100~120°C, gradually add the remaining SBC. The feeding method is the same as above, and set the heating nest temperature of the reactor A1 a...

Embodiment 2

[0030] Naphthenic oil 10KG; paraffin-based white oil 5KG; SIS 25KG; hydrogenated rosin resin 15KG; hydrogenated petroleum resin 30KG; pure C9 hydrogenated petroleum resin 15KG; antioxidant 1010 0.8KG / 100KG.

[0031]First put naphthenic oil, paraffin-based white oil and antioxidant 1010 into the 300L reaction kettle A1 filled with nitrogen through the gear pump (the air compressor 5 pressurizes the nitrogen in the nitrogen bottle to the reaction kettle A1) to heat, and start stirring The rotation speed of the motor is gradually adjusted to 15~25r / min. After the temperature rises to 70~80°C, half of the SIS is sucked through the vacuum feeding device 3. During the feeding process, the stirring motor is turned on at a low level, and the material is stirred evenly. Then gradually adjust the motor speed to 120r / min. After the temperature of the material rises to 100~120°C, gradually add the remaining SIS. The feeding method is the same as above, and set the heating nest temperature...

[0036] Naphthenic oil 15KG; SIS 25KG; hydrogenated rosin resin 25KG; hydrogenated petroleum resin 25KG; pure C9 hydrogenated petroleum resin 10KG; antioxidant 1010 0.8KG / 100KG.

[0037] First put naphthenic oil and antioxidant 1010 into the 300L reaction kettle A1 filled with nitrogen through the gear pump (the air compressor 5 pressurizes the nitrogen in the nitrogen bottle to the reaction kettle A1) to heat, turn on the stirring motor, and gradually adjust the speed After the temperature reaches 15~25r / min, when the temperature rises to 70~80°C, half of the SIS is sucked through the vacuum feeding device 3, and the stirring motor is turned on at a low level during the feeding process, and the material is stirred evenly. Then gradually adjust the motor speed to 120r / min. After the temperature of the material rises to 100~120°C, gradually add the remaining SIS. The feeding method is the same as above, and set the heating nest temperature of the reactor A1 at 160~180°C; after t...

Abstract

The invention relates to paper diapers, elastic composite materials and other care products, particularly a zero-creep low-temperature rubber string adhesive and a preparation method thereof. The invention is characterized in that the zero-creep low-temperature rubber string adhesive is mainly prepared from the following raw materials in parts by weight: 15-27 parts of high-compatibility softening agent, 45-80 parts of tackifying resin and 20-35 parts of SBC (styrene block copolymer) or SIS (styrene-isoprene-styrene). The zero-creep low-temperature rubber string adhesive has excellent coatability, and can be firmly attached to the rubber string, so that the rubber string does not have creep; and the zero-creep low-temperature rubber string adhesive has excellent adhesion effects on natural rubber strings, spandex fibers, Lycra fibers and many other rubber string materials, and can implement zero creep rate of the rubber string.

Description

(1) Technical field [0001] The invention relates to care products such as diapers and elastic composite materials, in particular to a zero-creep low-temperature rubber glue and a preparation method thereof. (2) Background technology [0002] The baby diaper (sheet) market has been pursuing a thinner urine-absorbing core layer and more comfortable and beautiful appearance. The rubber glue is used to fix the elastic material, so that the elastic material can be better bonded to the non-woven fabric and the bottom film, giving Hygienic products have better personal comfort and better leak-proof performance. The rubber rubber is required to have high creep resistance, good thermal stability, suitable opening time, good adhesion to elastic materials and PE backing materials or non-woven fabrics, no reverse seepage to non-woven fabrics, soft and elastic. [0003] Existing rubber glues are all high-temperature hot-melt adhesives with an operating temperature of 150-60°C. When ...
