Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the tensile strength and elongation at break of the existing oil edge are low, so that the leather bag may be often bent or pulled during use, which makes the oil edge easy to Breakage, making the oil edge easy to fall off, and thus easy to the appearance of the bag, therefore, there is still room for improvement

Embodiment 1

[0075] A processing technology for leather bag oil edge, comprising the following steps:

[0076] S1, prepare edge oil, specifically as follows:

[0077] In a 150L stirred tank, under normal temperature, add 17kg of polyurethane and 80kg of water, stir at a speed of 300r / min, add 13kg of acrylic acid, 10kg of pigment, 5kg of ethanol, 5kg of thickener, 2kg of defoamer, N , N-two (hydroxyethyl) cocamide 1kg, flurbiprofen 1kg, hydroxypivalate neopentyl glycol ester 0.3kg, stir well, form edge oil.

[0078] S2. Apply edge oil, as follows:

[0079] The edge oil prepared in step S1 is added to the edge oiling machine, and the leather is slowly slid over the feeding roller of the oil edge machine, so that the edge oil is evenly applied to the edge of the leather.

[0080] S3, dry, specifically as follows:

[0081] Pick up the leather evenly coated with edge oil with clips and let it dry to obtain the oiled edge of the leather bag.

[0082] In this embodiment, the thickener is car...

Embodiment 2

[0084] The difference with embodiment 1 is:

[0085] The consumption of each component that adds in the step S1 is as follows:

[0086] Polyurethane 16kg; Water 87.5kg; Acrylic acid 11.5kg; Pigment 7.5kg; Ethanol 4kg; Thickener 4kg; Defoamer 1.5kg; kg; Neopentyl glycol hydroxypivalate 0.2kg.

Embodiment 3

[0088] The difference with embodiment 1 is:

[0089] The consumption of each component that adds in the step S1 is as follows:

[0090] Polyurethane 15kg; Water 95kg; Acrylic acid 10kg; Pigment 5kg; Ethanol 3kg; Thickener 3kg; Neopentyl glycol valerate 0.1kg.

Abstract

The present invention relates to the technical field of leather bag processing, and relates to a processing technology of leather bag oil edge, which comprises the following steps: S1, preparing edge oil: stirring each component of edge oil evenly to make edge oil; S2, applying edge oil : adding the rim oil prepared in step S1 to the oil edging equipment, and evenly applying the rim oil to the edge of the leather; S3, drying; the rim oil includes the following components in parts by mass: 15-17 parts of polyurethane; 17 parts of acrylic acid 10‑13 parts; 5‑10 parts of pigment; 80‑95 parts of water; 3‑5 parts of ethanol; 3‑5 parts of thickener; 1‑2 parts of defoamer; Oleamide 0.5-1 part; flurbiprofen 1-1.5 part; hydroxypivalate neopentyl glycol ester 0.1-0.3 part. The invention has the effect of prolonging the service life of the oil side of the leather bag.

Description

technical field [0001] The invention relates to the technical field of leather bag processing, in particular to a processing technology for leather bag oil edges. Background technique [0002] At present, with the improvement of living standards, leather products have entered thousands of households and become a family necessity. In order to improve the problem of exposed edges after the combination of leather materials, leather edge oils of various colors are usually used to finish the edge of the leather bag to cover the exposed burr of the leather edge, so that the appearance of the leather bag is better beautified. [0003] Existing leather bag oil edge adopts the edge oil that polyurethane is made as main raw material to evenly smear on the edge part of leather usually, dries to form again. [0004] The above-mentioned existing technical solutions have the following defects: the tensile strength and elongation at break of the existing oil edge are low, so that the leat...
