Problems solved by technology

Since spraying starch does not need to be gelatinized, part of the starch will be lost with the water during the spraying process, resulting in a low retention rate
In addition, the starch modification process is complicated and the production cost is high, resulting in high production cost of cardboard

Embodiment 1

[0011] Example 1 The interlayer combined spray starch formula for producing white board paper (A, B grade), kraft liner board, and tea board paper (A, B grade) is as follows:

[0012] Native starch 80%, bentonite 15%, talcum powder 4.8%, preservative 2‰.

[0013] It can be prepared according to the production method provided by the invention.

[0014] The interlayer bonding spray starch prepared by the present invention is used by Fuyang Jintai Paper Industry Co., Ltd. to produce whiteboard paper. Paper Co., Ltd. currently uses Hangzhou-produced interlayer bonded spray starch which is comparable (see Attachment 1 D-2002-17 test report), but the cost is significantly lower.

[0015] The interlayer bonding spray starch prepared by the present invention is used by Anhui Shanying Paper Co., Ltd. to produce kraft linerboard, and the paper product is sampled and tested by the "National Light Industry Paper Quality Supervision and Inspection Shanghai Station", and the interlayer bon...

Embodiment 2

[0016] Example 2 The interlayer bonding spray starch formula for producing bobbin paper and white board paper is as follows:

[0017] Native starch 80%, bentonite 19.7%, preservative 3‰.

[0018] It can be prepared according to the production method provided by the invention.

[0019] The interlayer bonded spray starch prepared by the present invention is used by Shandong Changle Century Sunshine Paper Co., Ltd. to produce bobbin cardboard. Changle Century Sunshine Paper Co., Ltd. currently uses Shandong Zaozhuang Hengyuan interlayer bonded spray starch which is comparable (see Attachment 3 D-2002-20 test report), but the cost is significantly reduced.

Embodiment 3

[0020] Example 3 The formula for interlayer bonding and spraying starch for producing A-grade white board paper or high-grade corrugated base paper on a high-speed paper machine is as follows:

[0021] Original starch 70%, modified starch 25%, bentonite 4.9%, preservative 1‰.

[0022] The modified starch mentioned above is phospholipid starch, oxidized starch, acid hydrolyzed starch, enzyme hydrolyzed starch, cationic starch.

[0023] It can be prepared according to the production method provided by the invention.

[0024] In actual production and application, the ratio of interlayer combined spray starch can be adjusted according to the requirements of paper machine and paper type technology, and can be selected reasonably to form a variety of spray and spray starches. In summer, the amount of preservatives can be appropriately increased. . The combination of spraying starch between layers has been applied in actual production with good effect and can be popularized and use...

Abstract

A spray starch as interlayer adhesive of paperboard is prepared from raw starch (70-90%), bentone (2-20%), talc powder (0-5%), modified starch (0-25%) and antiseptic (0.1-0.6%) through stirring raw starch and sequentially adding others while stirring. Its advantages are simple technics, high effect and low cost.

Description

(1) Technical field [0001] The invention belongs to an interlayer binding enhancer for papermaking, in particular to a cardboard interlayer binding spray starch and a production method thereof. (2) Background technology [0002] The bonding between cardboard layers requires the use of spray starch, which is also called spray starch in production. Since the protection of recycled paper on environmental resources and the impact on social development have been valued by the whole world, the recycling of waste paper has played a very important role in the protection of environmental resources in our country. However, the reuse of secondary fibers requires special chemical treatment, such as deinking agents, reinforcing agents, drainage and retention aids, and resin barrier control agents. In particular, waste paper contains many resinous adhesive substances. If it is not handled carefully, it will cause sticking to cylinders and nets during papermaking, which will cause serious...
