Embodiment 1

[0027] According to the following weight ratio (parts by weight):

[0028]

[0029] The nitrocellulose resin of 40 parts by weight and the DMF of 30 parts by weight are mixed, stir; Add the polyurethane resin of 8 parts by weight and the alkyd resin of 35 parts by weight in the mixture obtained, stir evenly; Then in the mixture obtained Add 1.5 parts by weight of simethicone oil and 2 parts by weight of oleic acid amide, uniformly mix and filter to obtain the bursting resin for synthetic leather of the present invention. The bursting resin prepared above was tested for its technical performance, and the results are shown in Table 1.

[0030] The stirring, filtering and other methods used in the above preparation process are all conventional methods in the art.

Embodiment 2

[0032] According to the following weight ratio (parts by weight):

[0033]

Abstract

The invention discloses burst resin for synthetic leather and a preparation method of burst resin. The burst resin for the synthetic leather provided by the invention consists of the following components: nitro-cotton resin, alkyd resin, urethane resin, DMF (Dimethyl Formamide), oleamide and dimethyl silicone oil. The burst resin for the synthetic leather provided by the invention is an environment-friendly material and meets an environmental protection standard of European Union; each component for constituting the burst resin for the synthetic leather has the advantages of good mud-cracking effect, glossy bright face, high transparency and unique handfeel of slippery wax; and the synthetic leather using the burst resin has a good comprehensive effect.

Description

technical field [0001] The invention relates to a bursting resin for synthetic leather, in particular to a bursting resin for synthetic leather used in the back-stage process of synthetic leather. The invention also provides a preparation method of the bursting resin for synthetic leather. Background technique [0002] At present, the application of leather is very extensive, and the market demand is large, and its synthetic leather products will gradually become a popular trend in the future. Synthetic leather is widely used in the production of luggage, clothing, footwear and other products. Burst resin is used as the back-end material, which is generally used in the back-end process of synthetic leather. Existing bursting resins have the following deficiencies: [0003] (1) The large cracking effect of the resin is not good, and the bright surface and transparency are not good; [0004] (2) The viscosity, stability, and hand feel of synthetic leather products are not go...
