Conveying belt marking high adhesive force color paste and preparation method thereof

Abstract

The invention discloses conveying belt marking high adhesive force color paste which is prepared from an ingredient A and an ingredient B, wherein the ingredient A is prepared from the following raw materials in parts by weight: 44 to 48 parts of acetone, 42 to 45 parts of butanone solvent, 5 to 8 parts of polyurethane particle and 3 to 5.5 parts of benzimidazolone pigment; the ingredient B is prepared from the following raw materials in parts by weight: 100 parts of toluene diisocynate and 35 to 45 parts of hexamethylene diisocyanate; in use, the ingredient A and the ingredient B are evenly mixed according to the weight ratio of 1 to (0.85 to 0.13). The conveying belt marking high adhesive force color paste disclosed by the invention is prepared from selected raw materials; the contents of all the raw materials are optimized; benzimidazolone pigment in the prepared conveying belt marking high adhesive force color paste does not precipitate again, so that water dispersion stability isgood; the conveying belt marking high adhesive force color paste has the advantages of high adhesive force, small smell and the like on a PVC conveying belt.

Description

technical field [0001] The invention relates to the field of logistics conveyor belts, in particular to a high-adhesion color paste for conveyor belt markings and a preparation method thereof. Background technique [0002] Color paste is a semi-finished product made of pigment or pigment and filler dispersed in paint. The oily color paste with pure oil as the adhesive is called oily color paste. Resin color paste is called resin color paste with resin paint as adhesive. The pigment paste dispersed by adding surfactants in water as the medium is called water-based color paste. Because there are many types of paints, there are also many types of colorants. In order to better disperse pigments in the paint, a small amount of surfactant, zinc naphthenate, etc. is often added during the manufacturing process.

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate sorting, the sorting section of the logistics conveyor will place the parcels scattered to prevent untimely sorting due to excessive placement density, and low sorting efficiency if the density is too small. The conveyor belt will be accurately partitioned, and the partitions will be marked with yellow 40mm The yellow marking line was painted with yellow paint at the beginning of the period. Due to the poor adhesion between the paint and the PVC conveyor belt surface, it is easy to fall off, and the drying speed is also very slow. Large-scale production cannot be carried out, and the smell of paint will not dissipate for a long time, which will affect the sorting staff. Healthy body

Finally, the use of inkjet printer ink can solve the problem of drying speed and taste, but it can only be sprayed by air gun, which is a lot of waste. It is easy to cause the spray gun to be clogged, and the printing effect is not good, and the color material is floating on the surface of the tape after drying, which has poor durability and usually fades after 6 months
