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 an acrylic board veneer protection base paper; the following steps are carried out: taking 3-10 parts of cellulase, 1-8 parts of pectinase and 3-10 parts of xylanase in parts by weight , 0.1-0.8 part of alkanolamide, 0.1-0.6 part of Span-600.1-0.6 part, 75.7-88.8 part of water to prepare composite biological enzyme agent; add 1-5 parts of mixed pulp plate in pulper by weight, add 95- 99 parts of water, then add a compound biological enzyme agent of 100ppm-300ppm relative to the dry pulp weight, decompose for 5-30 minutes, and make a mixed pulp; send the mixed pulp into a refiner for refining, and the beating concentration is 1% ‑4%, refining to a beating degree of 20‑45°SR; the pulp is sequentially diluted, netted, pressed, dried and curled to obtain the finished product. The invention improves the beating degree of the pulp, shortens the refining time, reduces energy consumption, reduces pollution, and improves the specific gravity of the fiber form in the pulp by adding the compound biological enzyme agent with an optimized ratio in the pulping process of the base paper, so that the base paper The volume index of paper has been significantly improved.

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...
