Embodiment 1

[0018] A formula of water-based nitrocellulose varnish, the parts by weight of each component of the formula are 25 parts of resistant nitrocellulose, 100 parts of water, 200 parts of isooctyl acetate, 5 parts of plasticizer DOA, 10 parts of castor oil and EL Series emulsifier 5 parts. The plasticizer DOA is dioctyl adipate. Described EL series emulsifier is castor oil polyoxyethylene ether. There are no special restrictions on the source of the digested cotton, which is a deep-processed product of agricultural cotton and can be purchased from the market. However, in order to avoid the instability of the produced product, it is best to use the same region, the same factory, and the same viscosity product.

Embodiment 2

[0020] A formula of water-based nitrocellulose varnish, the parts by weight of each component of the formula are 25-60 parts of resistant nitrocellulose, 150 parts of water, 250 parts of isooctyl acetate, 20 parts of plasticizer DOA, and 20 parts of castor oil And 25 parts of EL series emulsifier. The plasticizer DOA is dioctyl adipate. Described EL series emulsifier is castor oil polyoxyethylene ether. There are no special restrictions on the source of the digested cotton, which is a deep-processed product of agricultural cotton and can be purchased from the market. However, in order to avoid the instability of the produced product, it is best to use the same region, the same factory, and the same viscosity product.

Embodiment 3

[0022] A formula of water-based nitrocellulose varnish, the parts by weight of each component of the formula are 60 parts of resistant nitrocellulose, 200 parts of water, 300 parts of isooctyl acetate, 40 parts of plasticizer DOA, 30 parts of castor oil and EL Series emulsifier 35 parts. The plasticizer DOA is dioctyl adipate. Described EL series emulsifier is castor oil polyoxyethylene ether. There are no special restrictions on the source of the digested cotton, which is a deep-processed product of agricultural cotton and can be purchased from the market. However, in order to avoid the instability of the produced product, it is best to use the same region, the same factory, and the same viscosity product.

[0023] Above three embodiments all adopt following preparation method to prepare:

[0024] A preparation method of the formula of water-based nitrocellulose varnish, the method comprises the following steps:

[0025] Step 1, adding the solvent isooctyl acetate and nitr...

Abstract

The invention relates to a composition of water-based nitrocotton gloss oil and relates to leather coatings. The composition comprises, by weight, 25-60 parts of nitrocotton, 100-200 parts of water, 200-300 parts of isooctyl acetate, 5-40 parts of plasticizer DOA, 10-30 parts of castor oil and 5-35 parts of EL-series emulsifier. A leather coating agent has high dry and moist resistance and comfortable handfeeling; the glossiness, gloss retainability and bending resistance of leather can be maintained, and the processed leather is comfortable in handfeeling and natural and has no plastic feeling; the composition does not contain organic solvents such as alkylphenol polyoxyethylene ether compounds and is safe and environmentally friendly.

Description

Technical field: [0001] The invention relates to a leather coating, in particular to a method for preparing a formula of water-based nitrocellulose varnish. Background technique: [0002] Medium-high gloss nitrocellulose varnish is an oil-in-water (O / W) structure composition, which is used for the surface coating of leather to enhance physical properties, improve brightness, and improve hand feel. The earliest solvent-based nitrocellulose varnish on the market was used, which was highly polluting, easy to catch fire, and relatively dangerous. At present, most factories use water-based nitrocellulose varnish. Large foreign companies have mature technology, but domestic nitrocellulose has defects such as instability, short storage time, and easy demulsification. In order to solve the above technical problems, a special method is proposed. A new technical solution. Invention content: [0003] The purpose of the present invention is to provide a preparation method for the fo...
