Abstract

The invention relates to the technical field of chemical products, in particular to water-borne touch oil and a preparation method thereof. The water-borne touch oil comprises raw materials in percentage by mass as follows: 45%-55% of polyether modified waterborne polyurethane dispersoid, 10%-20% of waterborne polyurethane dispersoid, 20%-30% of solvent-free anionic aliphatic modified waterborne polyurethane, 0.05%-0.15% of a defoaming agent, 2%-4% of elastic powder, 1%-3% of dipropylene glycol monomethyl ether, 3%-5% of cyclohexanol, 0.1%-0.3% of a coating additive, 0.1%-0.2% of a thickening agent and 0.1%-0.3% of an antiblocking agent. The phenomenon that the surface of a gift box or a printing carrier becomes white cannot be caused when the surface of the gift box or the printing carrier is coated with the water-borne touch oil and the gift box or the printing carrier is placed for a period of time, the product quality is good, and the economic benefit is good; when the gift box or the printing carrier coated with the water-borne touch oil is used for offset printing, the phenomenon of adhesion/smudging between printed matters cannot be caused, the defective percentage is low, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a tactile water oil and a preparation method thereof. Background technique [0002] In the prior art, a layer of tactile oil is coated on the surface of the gift box or printing carrier when manufacturing exquisite gift boxes or fine prints, and then the required patterns are printed to obtain the finished product. However, after the existing tactile oil is applied to the surface of the gift box or printing carrier, the surface of the gift box or printing carrier will turn white after being left for a period of time (about 2 months), resulting in poor product quality and poor economic benefits. In addition, when the gift box or printing carrier coated with tactile oil is applied to offset printing, the printed matter is very prone to sticking / sticking, resulting in scrapped printed matter, high defective rate, increased production costs, and poor economic benefits. Co...
