Paint for coating chromatic bobbin printed sheet and preparation method thereof

Abstract

The invention discloses a coating for painting colored yarn-tube face paper, which is made of the following materials: carboxylated styrene-butadiene rubber latex, oxidized starch, acid or direct dye, zirconium salt water-resistance agent and water. The production method of the coating of the invention made by the above materials is that: the oxidized starch is added into the water in proportion, mixed and heated to over 80 degree centigrade to make the oxidized starch fully gelatinized, and then the acid or the direct dye is added after being cooled lower than 60 degree centigrade for dissolution, carboxylated styrene-butadiene rubber latex is added at 10-40 degree centigrade before use, and proper zirconium salt water-resistance agent is added and stirred uniformly. The coat can be painted on paper, base paper used can be paper or cardboard of white, natural and colored with certain strength, crossed and solidified under catalyst or heating, thereby achieving certain performance of oil resistance, water resistance and operating requirements of non-decolorization, antistatic, etc. The invention is also a novel environmental protection product.

Description

technical field [0001] The invention relates to a paint for coating colored bobbin face paper, and also designs a preparation method and application of the paint for coating colored bobbin face paper. Background technique [0002] The bobbin surface paper is used as the spindle core for winding the yarn in the production process of the textile industry. The spindle core (also known as the bobbin) is wrapped with yarn during spinning, and the surface of the bobbin has bright colors. Under normal circumstances These bobbins are single use. Since the bobbin paper is in direct contact with the yarn, and the yarn will adhere to a small amount of mineral oil commonly known as spindle oil and a small amount of water during the spinning and spinning process, if the dye of the bobbin paper is oil-soluble and water-soluble It will make the spindle yarn dyed and cannot be used. Therefore, high-quality bobbin paper not only has good stretchability and shape stability, but also must hav...

The traditional bobbin surface paper is parchment paper. Parchment paper is dyed in the pulp before papermaking, and the paper surface is parchmentized with concentrated sulfuric acid. A large amount of colored wastewater (or containing high-concentration dye components) is discharged during the production of parchment paper. colorless wastewater), waste acid, causing environmental pollution
