AI Technical Summary

Problems solved by technology

[0004] 1. The glue is generally water-based. The stickiness and initial viscosity of the glue are unstable, and the aging resistance is not enough. These shortcomings bring hidden dangers to the performance of the product and affect the life of the product.
[0005] 2. Ordinary water glue products have a strong smell, the performance of the glue is unstable, and the environmental protection performance is poor, which leads to a reduction in the service life of the product and a lack of guarantee for safety performance

Embodiment 1

[0026] Labels of daily chemical products:

[0027] 1. Treatment of glassine backing paper:

[0028] The white glassine base paper is treated with a solvent-free silicone oil solution on the surface. The solvent-free silicone oil solution is formed by stirring a solvent-free silicone, a curing agent (such as a platinum complex) and a bridging agent (such as methyl hydrogen-containing silicone oil). The ratio is: 100:(3~3.5):(4~5), through a 30m long oven, the speed is 100~120m / min, the amount of silicon coating is 1.1~1.2g / square meter, and then at a temperature of 130 ℃~150℃ to dry in an oven to make a solvent-free composite backing paper.

[0029] 2. Glue preparation:

[0030] When the temperature of the reaction boiler is increased to 190-200°C, put in 40KG of white ring oil, stir for ten minutes, add 60KG of thermoplastic rubber and continue stirring to melt the rubber. The time is about 2 hours, and 35KG of C5 hydrogenated petroleum resin, glycerin resin Put 35KG, 50KG ...

[0034] Preparation of logistics label materials:

[0035] 1. Treatment of glassine backing paper:

[0036] The blue glassine base paper is treated with a solvent-free silicone oil solution on the surface. The solvent-free silicone oil solution is formed by stirring with a solvent-free silicone, a curing agent and a bridging agent. The weight ratio is: 100:3:4.6. The speed is 100-120 m / min, the amount of silicon coating is 1.1-1.2 g / m2, and then dried in an oven at a temperature of 130°C-150°C to make a solvent-free composite backing paper!

[0037] 2. Glue preparation:

[0038] When the temperature of the reaction boiler is increased to 190-200°C, put in 40KG of white ring oil, stir for ten minutes, add 60KG of thermoplastic rubber and continue stirring to melt the rubber. The time is 2.5 hours. Add 35KG of C5 hydrogenated petroleum resin and 35KG of glycerin resin. , 50KG of terpene resin and 1.3KG of antioxidant are put into the boiler according to the proportion of the fo...

Abstract

The invention belongs to the technical field of non-setting adhesive materials, and specifically relates to environment-friendly hot-melt glue and a preparation method thereof. The preparation method comprises the following steps: putting thermal-plastic rubber, C5 hydrogenated petroleum resin, glycerin resin, antioxidant and white ring oil used as raw materials in a proper weight ratio into a reaction boiler, stirring the mixture for about 4 hours, and then obtaining a finished product. The glue has stable cohesion and tack, good stripping quality, ageing resistance and good holding force to adhered objects, needs no drying process, has a solid content of 100g, greatly saves energy, has low cost, becomes a glue selected by producer of non-setting adhesive material, and can be widely applied to tags and seals of medical supplies and daily use chemical industry, tags of food packages, logistics tags, and the like.

Description

technical field [0001] The invention belongs to the technical field of self-adhesive materials, and specifically relates to an environmentally friendly hot-melt glue that can be used in dozens of industries such as medicine, food, daily chemical, office, logistics, and industry, and a preparation method thereof. Background technique [0002] With the continuous development of society, people pay more and more attention to the environmental protection of self-adhesive materials and the performance of glue. It is popular in more than a dozen industries, among which the demand for self-adhesive materials such as medicine, food, and daily chemicals continues to rise. , Environmentally friendly self-adhesive materials have become people's first choice. [0003] At present, the glue of self-adhesive materials used in medicine, food, office, etc. in the international and domestic markets are as follows: [0004] 1. The glue is generally water-based. The stickiness and initial visc...
