Embodiment 1

[0020] The invention discloses a printing and packaging paper with low printing gloss. The steps are as follows:

[0021] Step 1: First of all, it is necessary to mix an appropriate number of softwood pulp, hardwood pulp and cotton linter pulp with water, place them in a cylinder paper machine and twist them into fibers, and then copy the fibers in the water into wet paper sheets. Then use a high-frequency vibrating frame sieve to filter, the mesh number of the sieve is: 120-140 mesh / hour, and then dry and press the sieved base paper with a duckbill air knife to obtain a dried and formed base paper;

[0022] Step 2: Put water, various types of kaolin, various types of latex, polyvinyl alcohol and other materials in the inside of the paint preparation barrel with a solid content of 32-35%, and the internal rotor speed needs to reach 800-1500r / min , fully stirred for 140-160 minutes, and then filtered the mixed material after stirring with a vibrating frame sieve. The mesh numbe...

Embodiment 2

[0027] The invention discloses a printing and packaging paper with low printing gloss. The steps are as follows:

[0028] Step 1: First of all, it is necessary to mix an appropriate number of softwood pulp, hardwood pulp and cotton linter pulp with water, place them in a cylinder paper machine and twist them into fibers, and then copy the fibers in the water into wet paper sheets. Then use a high-frequency vibrating frame sieve to filter, the mesh number of the sieve is: 115-135 mesh / hour, and then dry and press the sieved base paper with a duckbill air knife to obtain a dried and formed base paper;

[0029] Step 2: Put water, various types of kaolin, various types of latex, polyvinyl alcohol and other materials in the inside of the paint preparation barrel with a solid content of 34-37%, and the internal rotor speed needs to reach 800-1500r / min , fully stirred for 140-160 minutes, and then filtered the mixed material after stirring with a vibrating frame sieve. The mesh numbe...

Embodiment 3

[0034] The invention discloses a printing and packaging paper with low printing gloss. The steps are as follows:

[0035] Step 1: First of all, it is necessary to mix an appropriate number of softwood pulp, hardwood pulp and cotton linter pulp with water, place them in a cylinder paper machine and twist them into fibers, and then copy the fibers in the water into wet paper sheets. Then use a high-frequency vibrating frame sieve to filter, the mesh number of the sieve is: 110-130 mesh / hour, and then dry and press the sieved base paper with a duckbill air knife to obtain a dried and formed base paper;

[0036] Step 2: Put water, various types of kaolin, various types of latex, polyvinyl alcohol and other materials in the inside of the paint preparation barrel with a solid content of 36-41%, and the internal rotor speed needs to reach 800-1500r / min , fully stirred for 140-160 minutes, and then filtered the mixed material after stirring with a vibrating frame sieve. The mesh numbe...

Abstract

The invention discloses printing and packaging paper with low printing glossiness. The printing and packaging paper comprises a direct welding paint layer coated on the inner layer, a self-adhesive layer coated on the middle layer and an anti-oxidation protective layer coated on the outer layer. The printing packaging paper with low printing glossiness is sequentially coated with three paint layers from inside to outside, wherein the straight welding paint layer on the inner layer can be firmly attached to the outer portion of an internal copper wire, the problem that a traditional enameled wire shell is prone to falling off, and consequently the service life of the traditional enameled wire shell is shortened is solved. The self-adhesive layer in the middle can be self-adhered firmly in avery short time after being coated, so that the effect of data transmission of the internal copper wire is protected, the built-in material can insulate heat, and the heat-resistant grade of the product is improved; and finally, the anti-oxidation protective layer on the outer side can become a shell with toughness after being subjected to hot melting.

Description

technical field [0001] The invention relates to the technical field of packaging paper preparation, in particular to a printing and packaging paper with low printing gloss. Background technique [0002] Wrapping paper refers to the paper used for packaging. It has high strength, low moisture content, low air permeability, no corrosion, and has a certain water resistance. It is also beautiful to use. According to the characteristics of the product, the wrapping paper has corresponding special properties. Among the paper, the largest amount is used to pack bulk powdery industrial and agricultural raw materials, such as paper bag paper for cement, chemical fertilizers, etc., which are generally made of more than 3 to 4 layers of paper, so it is also called multi-layer paper bag paper to distinguish it from packaging. Other bag paper for light goods. This kind of wrapping paper mainly requires high strength, heavy load resistance, impact resistance, and proper air permeability....
