preparation example Construction

[0028] The preparation method of the waterproof film-forming agent for leather care is to weigh the raw materials according to the above composition, and mix and stir to obtain the waterproof film-former for leather care.

[0029] Preferably, in the preparation method, the mixing and stirring is specifically placing the materials in a reaction kettle, heating to 80° C. to 90° C. under vacuum conditions, and mixing and stirring for 50 minutes to 70 minutes.

[0030] The usage method of this dermis care waterproof film-forming agent is to spray or smear the dermis care waterproof film-forming agent on the surface of dermis products.

[0031] Further, it is advisable to spray or smear the dosage of the waterproof film-forming agent for dermis care to evenly cover the surface of the dermis product to form a thin protective film layer.

Embodiment 1

[0034] Example 1 The raw materials and mass percentages of the leather care waterproof film-forming agent are shown in Table 1. The fluorine-containing polymer emulsion used in Example 1 is a perfluoroalkyl ethyl acrylate emulsion, and the ammonia value of the amino silicone oil is 0.27 mmol / g.

[0035] Table 1 embodiment 1 dermis care waterproof film-forming agent composition

[0036] raw material Mass percentage (%) Fluoropolymer Emulsion 50 Amino silicone oil 7 isotridecyl alcohol 2 Aliphatic polyurethane resin 10 Emulsified silicone oil 10 Polyether modified silicone oil 1 Deionized water 20

[0037] After the raw materials described in Table 1 were weighed according to the proportion, they were placed in a reaction kettle, heated to 85°C under vacuum conditions (0.01MPa~0.02MPa), stirred for 60min, then cooled to room temperature and discharged to obtain Example 1 Waterproof film former for dermal care.

Embodiment 2

[0042] Example 2 The raw materials and mass percentages of the leather care waterproof film-forming agent are shown in Table 2. The used raw material of embodiment 2 is identical with embodiment 1 unless otherwise specified.

[0043] Table 2 embodiment 2 dermis care waterproof film-forming agent composition

[0044] raw material Mass percentage (%) Fluoropolymer Emulsion 60 Amino silicone oil 7 isotridecyl alcohol 3 Aliphatic polyurethane resin 1 Emulsified silicone oil 7 Polyether modified silicone oil 2 Deionized water 20

[0045] After the raw materials described in Table 2 were weighed according to the proportion, they were placed in a reaction kettle, heated to 85°C under vacuum conditions (0.01MPa~0.02MPa), stirred for 60min, then cooled to room temperature and discharged to obtain Example 2 Waterproof film former for dermal care. The product of Example 2 is a product aimed at dermal scrub. Genuine nubuck leathe...

Abstract

The invention discloses a leather-care waterproof film-forming agent and a preparation method thereof. The leather-care waterproof film-forming agent contains the following raw materials in percentageby mass: 50%-60% of a fluorine-containing polymer emulsion, 5%-7% of amino silicon oil, 2%-7% of iso-tridecanol, 1%-3% of polyether modified silicone oil, 0-10% of aliphatic polyurethane resin, 0-10%of emulsified silicone oil, 0-15% of isopropanol and the balance of water. The invention simultaneously discloses a preparation method and a use method of the leather-care waterproof film-forming agent. A layer of waterproof and dirt-proof protecting film can be formed on the surface of all leather by the leather-care waterproof film-forming agent, so that the leather is protected, and meanwhile,a hydrophobic effect is achieved.

Description

technical field [0001] The invention relates to a waterproof film-forming agent for dermis care and a preparation method thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather has a wide range of uses and can be used to make a variety of daily necessities, such as leather shoes and clothes. The raw material used for genuine leather is natural leather. Natural leather is superior to other materials in terms of flexibility, breathability, wear resistance, folding resistance, and aesthetics, and is an essential material for high-end leather products. However, these products are very prone to water seepage. Due to wet weather or rain, the leather surface is easily wet or contaminated with various moisture or water vapor. If the genuine leather products are not waterproofed, the leather is easy to rot and deteriorate, which seriously shortens the servic...
