Embodiment 1

[0009] Embodiment 1: a kind of moisture curing type leather bright finishing agent of the present invention, measure each component weight respectively and be: toluene diisocyanate 35KG, trimethylolethane 22KG, dibenzoyl peroxide 15KG, trichloroethylene 10KG, 5KG dibasic lead stearate, 9KG organo-modified polysiloxane, 4KG propyl gallate.

[0010] The preparation method and process steps of the above formula are as follows: 35KG of toluene diisocyanate, 22KG of trimethylolethane, 15KG of dibenzoyl peroxide, 5KG of dibasic lead stearate, and 9KG of organo-modified polysiloxane 1. Put 4KG of propyl gallate into the reaction kettle and heat to 85°C, stir for about 10 hours until the reaction end point is detected; add 10KG of trichlorethylene into the reaction kettle and stir for 1.5 hours; cool to room temperature.

Embodiment 2

[0011] Embodiment 2: a kind of moisture-curing type leather bright finishing agent of the present invention, measure each component weight respectively: toluene diisocyanate 41KG, trimethylolethane 18KG, dibenzoyl peroxide 20KG, trichloro Vinyl 11KG, dibasic lead stearate 3KG, organo-modified polysiloxane 5KG, propyl gallate 2KG.

[0012] The preparation method and process steps of the above formula are as follows: 41KG of toluene diisocyanate, 18KG of trimethylolethane, 20KG of dibenzoyl peroxide, 3KG of dibasic lead stearate, 5KG of organo-modified polysiloxane 2. Put 2KG of propyl gallate into the reactor and heat to 90°C, stir for about 9.5 hours until the end of the reaction is detected; add 11KG of trichlorethylene into the reactor and stir for 1 hour; cool to room temperature.

Abstract

The invention discloses a moisture curing type leather polishing coating agent. The moisture curing type leather polishing coating agent comprises, by weight, 34-43% of tolylene diisocyanate, 9-36% of trimethylolethane, 14-22% of dibenzoyl peroxide, 9-16% of trichloroethylene, 2-6% of dibasic lead stearate, 4-10% of organic group modified polysiloxane, and 1-5% of propyl gallate. Compared to the prior art, with the present invention, the moisture curing type leather polishing coating agent has excellent low temperature flexing resistance; after the moisture curing type leather polishing coating agent is coated on the leather, characteristics of high brightness, strong crystal sense, and strong three-dimensional effect are achieved, and the good visual effect is provided.

Description

technical field [0001] The invention relates to the technical field of leather finishing agents, in particular to a moisture-curing bright leather finishing agent. Background technique [0002] Finishing agent is a slurry that is mainly used for beautifying the surface of leather, improving durability, correcting grain defects, improving commercial value, and increasing color varieties. [0003] Although the previous finishing agents have improved the gloss of synthetic leather to a certain extent, they have not reached the ideal level, and the low temperature bending resistance is poor, and the overall performance is not high. With the wide application of leather materials, the performance requirements for surface finishing agents such as glossiness and low-temperature bending resistance are also increasing. Therefore, the current finishing agents need to be further improved and improved. Contents of the invention [0004] In view of the above-mentioned problems existing...
