Abstract
Description
technical field
[0001] The invention belongs to the technical field of composite materials, and specifically relates to an environment-friendly pressure-sensitive adhesive composite material 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 and the continuous improvement of people's living standards, people pay more and more attention to the environmental protection performance of pasting composite materials, which involves more than a dozen industries, among which the demand for pasting composite materials used in medicine, food, daily chemicals, etc. On the rise, environmentally friendly pasting composite materials have become people's first choice.
[0003] At present, the pasting composite materials used in medicine, food, office, etc. in the international market are as follows:
[0004] 1. The substra...
Examples
Embodiment 1
[0038] 1 Handling of glassine backing paper:
[0039] Coat the surface of the white glassine base paper with a solvent-free working solution, which is formed by stirring with a solvent-free silicone (DW001) and a curing agent (DW004), at a ratio of 1:0.08, and passes through an oven with a length of 25m. The speed is 80-90 m / min, the silicon content is 1.3-1.4 g / m2, and then dried in an oven at a temperature of 140°C-150°C to obtain a solvent-free composite backing paper.
[0040] 2. Glue preparation:
[0041] According to the combined formula, mix and stir octyl fat 600 (KG, the same below), butyl fat 300, acrylic acid 70, light ethyl fat 70, vinyl acetate 80, perammonium 1.8 and ammonium bicarbonate 1.6 to produce an emulsion. Add appropriate amount of additives. Heat the rubber-making boiler to 70-80°C, put in the emulsion in batches, and stir to make it produce a chemical reaction, keep the temperature of the chemical reaction in the rubber-making boiler at 85-90°C until...
Embodiment 2
[0045] 1. Treatment of glassine backing paper:
[0046] Coat the surface of the blue glassine base paper with a solvent-free working solution. The solvent-free working solution is formed by stirring with a solvent-free silicone (DW001) and a curing agent (DW004). The ratio is: 1:0.07, and it passes through a 25m long oven. The speed is 70-80 m / min, the silicon content is 1.2-1.3 g / m2, and then dried in an oven at a temperature of 130°C-140°C to obtain a solvent-free composite bottom paper.
[0047] 2. Glue preparation:
[0048] According to the composition formula, stir octyl fat 400 (KG, the same below), butyl fat 160, acrylic acid 45, light ethyl fat 50, vinyl acetate 50, perammonium 0.6 and ammonium bicarbonate 0.9 to form a mixed emulsion, and the rubber boiler When heating to 70-80°C, add the emulsion gradually to cause a chemical reaction, keep the temperature of the chemical reaction in the rubber boiler at 80-85°C until all the emulsion is added, and keep the temperat...
Embodiment 3
[0052] 1. Treatment of glassine backing paper:
[0053] Coat the surface of the white glassine base paper with a solvent-free working solution, which is formed by stirring with a solvent-free silicone (DW001) and a curing agent (DW004), at a ratio of 1:0.08, passing through an oven with a length of 25m. The speed is 70-80 m / min, the silicon content is 1.3-1.4 g / m2, and then dried in an oven at a temperature of 130°C-140°C to obtain a solvent-free composite backing paper.
[0054] 2. Glue preparation:
[0055]According to the component formula, mix and stir octyl 450 (KG, the same below), butyl fat 180, acrylic acid 45, light ethyl fat 50, vinyl acetate 50, perammonium 1 and ammonium bicarbonate 0.8 to produce an emulsion. When the rubber-making boiler is heated to 70-80°C, the emulsion is gradually added in batches under stirring, and stirred to make it produce a chemical reaction. Keep the temperature of the chemical reaction in the rubber boiler at about 85°C until all the...
