Problems solved by technology

At present, in the carbonless copy paper production line with a paper machine speed of up to 1000 m / min, the base paper sizing still needs to be controlled at 20 g / m 2 The following process requirements fully show that even for high-speed paper machines, the quality of sizing still determines the migration of coatings to a large extent, thus affecting the coating effect

Embodiment 1

[0015] The surface sizing agent for papermaking is prepared from the following raw materials in parts by weight: epoxy siloxane: iron-free aluminum sulfate: methenamine: disodium lauryl sulfosuccinate : ascorbic acid: acrylonitrile: methacrylic acid: deionized water = 4.0: 8.0: 0.9: 16: 7: 7.5: 1.4: 53.

[0016] The method for preparing the surface sizing agent for papermaking comprises the following steps:

[0017] First add deionized water and iron-free aluminum sulfate into the reaction kettle, then add the stabilizer urotropine, after it is completely dissolved, add other raw materials according to the formula ratio, stir for 30-60 minutes, keep at room temperature for 20-30 hours, and then filter. Get the finished product.

Embodiment 2

[0019] The surface sizing agent for papermaking is prepared from the following raw materials in parts by weight: epoxy siloxane: iron-free aluminum sulfate: methenamine: disodium lauryl sulfosuccinate : ascorbic acid: acrylonitrile: methacrylic acid: deionized water = 5.0: 6.5: 1.0: 15: 6: 7.5: 1.5: 55. Others are with embodiment 1.

Abstract

The invention relates to a surface sizing agent for paper manufacture, falling into the technical field of paper manufacture. The surface sizing agent is prepared from epoxysiloxane, iron-free aluminum sulfate, urotropine, disodium lauryl sulfosuccinate, ascorbic acid, acrylonitrile, methylacrylic acid and deionized water at weight ratio of (3.0-7.0):(5.0-12):(0.5-1.5):(10-20):(2-10):(4.5-12.5):(1.0-2.0):(50-60). The invention is suitable for manual cleaning and tableware mechanical cleaning, generates no irritating on skin / toxicity, has simple manufacture process, low cost and high biodegration speed, generates no pollution after flowing into natural environment, and achieves abundant foam, strong cleaning and dirt-removing capability, good stability and better social benefit.

Description

technical field [0001] The invention relates to a surface sizing agent for papermaking and belongs to the technical field of papermaking. Background technique [0002] At present, the paper industry and printing technology are developing at a high speed, and the role of surface sizing is becoming more and more prominent. Everyone in the paper industry knows that base paper sizing is an essential and important means to control the migration of paint during the coating process and ensure the quality of the coating. From the COBB value of base paper and the penetration time detected by PDC, it can be seen that the sizing of base paper is closely related to the migration rate of water-soluble components. [0003] With the increase of sizing degree of base paper, the migration time of PDA is extended, and the migration rate of water is accelerated sharply. When the water absorption weight of base paper is 29g / m 2 At this time, the minimum time for moisture to migrate through t...
