Embodiment 1

[0032] Embodiment 1: A kind of preparation method of acrylic board veneer protection base paper, carry out according to the following steps: Take 10 parts of cellulase, 8 parts of pectinase, 10 parts of xylanase, 0.8 parts of alkanolamide by weight 0.6 parts, Span-60, 75.7 parts of water, mixed to obtain a compound biological enzyme agent; then put 0.5 parts of coniferous wood pulp board and 0.5 part of hardwood pulp board into the pulper, add 99 parts of water, and the pulp board dissolves Pulp is formed, the water temperature is 25°C, and then relative dry pulp is added to the raw material solution (that is, the dry mass of the pulp in the pulper after removing water; the ratio of the relative dry mass of the softwood pulp board and the hardwood pulp board is the same. It is a conventional parameter, which can be calculated by multiplying the weight of the softwood pulp board or the weight of the hardwood pulp board to calculate the weight of the relative dry pulp) weight 300...

Embodiment 2

[0033] Embodiment 2: A kind of preparation method of acrylic board veneer protection base paper, carry out according to the following steps: Take 8 parts of cellulase, 6 parts of pectinase, 8 parts of xylanase, 0.7 parts of alkanolamide by weight 0.5 parts of Span-60, 76.8 parts of water, mixed to obtain a compound biological enzyme agent; then put 1.4 parts of coniferous wood pulp board and 0.6 part of hardwood pulp board into the pulper, add 98 parts of water, and the pulp board dissolves To form pulp, the water temperature is 25°C, and then add a compound biological enzyme agent of 250ppm relative to the weight of the dry pulp to the raw material solution for deflaking. The flaking time is 25min. It is 270kw / h, the beating concentration is 2%, the beating degree is 40°SR, and the pulp is obtained. After the above-mentioned processed pulp is subjected to follow-up operations according to the conventional process, after the concentration of the pulp is diluted to 0.4%, it is ...

Embodiment 3

[0034]Embodiment 3: A kind of preparation method of acrylic board veneer protection base paper, carry out according to the following steps: Take 5 parts of cellulase, 2 parts of pectinase, 5 parts of xylanase, 0.5 parts of alkanolamide by weight 0.3 parts of Span-60, 83.2 parts of water, mixed to obtain a compound biological enzyme agent, then put 1.2 parts of coniferous wood pulp board and 0.8 part of hardwood pulp board into the pulper, add 98 parts of water, and the pulp board dissolves To form pulp, the water temperature is 25°C, and then add a compound biological enzyme agent with a relative dry pulp weight of 200ppm to the raw material solution to decompose. The decompression time is 20 minutes, and the decomposed pulp is sent to a refiner for refining. The total power of the refining It is 270kw / h, the beating concentration is 2%, and the beating degree is 35°SR, and the pulp is obtained. After the above-mentioned processed pulp is subjected to follow-up operations acco...

Abstract

The invention discloses a preparation method of acrylic board surface lining protective body paper. The preparation method comprises following steps: by weight, 3 to 10 parts of cellulase, 1 to 8 parts of pectase, 3 to 10 parts of xylanase, 0.1 to 0.8 part of an alkylolamide, 0.1 to 0.6 part of Span-60, and 75.7 to 88.8 parts of water are combined to prepare a composite bio-enzyme preparation; byweight, 1 to 5 parts of a mixed pulpboard is introduced into a pulper, 95 to 99 parts of water is added, the composite bio-enzyme preparation is added, and defibering is carried out for 5 to 30min soas to obtain a mixed slurry, wherein the adding amount of the composite bio-enzyme preparation accounts for 100 to 300ppm of the weight amount of absolutely dry paper pulp; the mixed slurry is introduced into a pulping machine for pulp refining, pulping concentration ranges from 1 to 4%, and pulp refining is carried out until beating degree is 20 to 45 DEG SR; obtained paper pulp is subjected to dilution, screen moulding, squeezing, drying, and curling processing so as to obtain a finished product. According to the preparation method, the composite bio-enzyme preparation at an optimal ratio isadded in body paper pulp refining process, so that paper pulp beating degree is increased, pulp refining time is shortened, energy consumption is reduced, pollution is reduced, the ratio of fiber morphological substances in paper pulp is improved, and body paper object amount index is increased obviously.

Description

technical field [0001] The invention relates to a preparation method of an acrylic board veneer protection base paper, which belongs to the field of papermaking. Background technique [0002] The paper industry is an important industry closely related to the development of the national economy. However, the paper industry is also one of the industries with high energy consumption and heavy pollution. my country is the world's largest paper-making country, with a production volume of 101.1 million tons in 2013, accounting for about 25% of the world's total production. Among them, raw coal and purchased electricity accounted for 73% and 23% of the total energy consumption in the papermaking process respectively, far behind other papermaking countries in the world. Moreover, our energy consumption in papermaking accounts for 15% to 35% of the total cost of papermaking enterprises, which is the second largest cost besides the cost of fiber raw materials. As the country and the...
