preparation example Construction

[0009] The invention provides a preparation method of composite paper, comprising: raw wood pulp, bark, hemp, straw, glass fiber, inorganic filler and lime water according to the ratio of 100:20-30:1-5:2-5:5 -15: 15-25: 200-300 weight ratio for mixing and cooking to obtain pulp; washing, blanching, threshering, scooping, drying and baking of the pulp to obtain the composite Paper.

[0010] In the above technical solution, the type of the inorganic filler and its preparation method can be selected in a wide range, but in order to further improve the strength of the composite paper prepared, preferably, the inorganic filler is prepared by the following method : kaolin, chitin fiber, bamboo fiber, ceramic fiber, starch, hydrotalcite, diatomite and yttrium are mixed, heat treated, ground and sieved to prepare the inorganic filler.

[0011] In the preparation process of the above-mentioned composite paper, the specific ratio of the raw materials of the inorganic filler can be sele...

preparation example 1

[0021] Kaolin, chitin fiber (extracted from the shell of shrimp, crab, snail and centipede mixed in the shell at a weight ratio of 1:1:1:2), bamboo fiber, ceramic fiber, starch (mung bean starch, tapioca starch, Sweet potato starch and corn starch are mixed according to the weight ratio of 1:1:2:1), hydrotalcite, diatomaceous earth and yttrium are mixed according to the weight ratio of 100:5:1:3:5:1:2:0.5; , under a nitrogen atmosphere, the temperature was raised from room temperature to 700°C and maintained at 700°C for 1 hour, wherein the heating rate was 10°C / min; then the temperature was lowered to 100°C at a cooling rate of 10°C / min and then directly cooled with water; finally, Grind and sieve to obtain the inorganic filler with an average particle size of 400 μm; denoted as W1.

preparation example 2

[0023] Kaolin, chitin fiber (extracted from the shells of shrimps, crabs, locusts, snails and centipedes in a weight ratio of 1:1:1:1:1), bamboo fibers, ceramic fibers, sweet potato starch, water Talc, diatomaceous earth and yttrium were mixed according to a weight ratio of 100:8:3:4:8:3:7:0.8; then, under a nitrogen atmosphere, the temperature was raised from room temperature to 750°C and maintained at 750°C for 1h, Among them, the heating rate is 15°C / min; then the temperature is lowered to 150°C at a cooling rate of 15°C / min and then directly water-cooled; finally, the inorganic filler with an average particle size of 450 μm is obtained by grinding and sieving; denoted as W2.

Abstract

The invention discloses a composite paper and a production method thereof. The production method comprises the following steps: mixing raw wood pulp, barks, hemp, straws, glass fibers, an inorganic filler and limewater according to a weight ratio of 100:(20-30):(1-5):(2-5):(5-15):(15-25):(200-300), and boiling the obtained mixture to prepare a paper pulp; and washing, bleaching and beating the paper pulp, picking up paper, and squeezing and baking the paper to obtain the composite paper. In the invention, the raw wood pulp, barks, hemp, straws, glass fibers, an inorganic filler and limewater are mixed according to a specific ratio, and are boiled to prepare the paper pulp; and the inorganic filler added into the raw materials of the paper in the production method improves the strength of the produce paper and increases the burst index of the paper.

Description

technical field [0001] The invention relates to the field of paper production, in particular to a composite paper and a preparation method. Background technique [0002] Plastic bags are very common in daily life, because of their convenience, they are often used to pack and store food. The most common plastic bags can be classified into plastic bags and paper-plastic composite plastic bags according to their materials. Although paper plastic bags are environmentally friendly, they are far inferior to plastic bags in terms of mechanical strength and durability. Will affect the user's health. Contents of the invention [0003] The object of the present invention is to provide a composite paper and a preparation method thereof. The composite paper has high mechanical strength, high burst index and excellent antibacterial performance, and is suitable for preparing paper-plastic composite materials. [0004] In order to achieve the above object, the present invention provid...
