Abstract

The invention discloses a card board waterproof adhesive that is made up from 10-15% starch, 1-25% borax, 2-5% caustic soda, 0.5-10% stabilizer, 0.5-10% glue coupling agent, 0.02-8% resin, 10-85% water. It has strong binding powder, stable capability, low cost and good quality.

Description

Paper board production water-proof adhesive

Technical field

The present invention relates to a kind of tackiness agent, specifically relate to the tackiness agent of paperboard grade (stock).

Background technology

Existing cardboard generally is by the laminated paper formation that is bonded together, thereby its tackiness agent is an important source material that concerns the production quality, the cardboard tackiness agent of prior art generally is to adopt starch and oxygenant, catalyzer etc. are made, also there is a small amount of borax of interpolation while, the performance index of its cardboard such as anti-broken (Mpa), water-fast and ring crush index is on the low side, as application number is 03104745, the applying date is on February 28th, 2003, denomination of invention is the patent application that single-side machine and corrugated paper board production line are used water-resisting type Starch Adhesive and method for making thereof, it discloses a kind of adhesive for corrugated paperboard of starch base, it is characterized in that, it is formed by adding inorganic bentonite and other compositions in the starch, its compositing range is: 14-18% starch, the 5-20% wilkinite, the 0.8-1.0% hydrogen peroxide, concentration 30%, the 0.02-0.04% ferrous ammonium sulphate, 1.0-1.62% sodium hydroxide, 0.1-0.2% borax (1.0 water Sodium Tetraborate), 79.1-54.2% water.Its performance index of cardboard that adopt this technology to produce are lower equally, when under the wet weather situation, or under the refrigeration situation the easy moisture absorption of its cardboard, thereby cracky, thereby influence result of use, simultaneously because the wetness of paper is higher, the production rate of cardboard is than reducing greatly, thereby influenced production efficiency.

Summary of the invention

The object of the present invention is to provide and a kind ofly can effectively improve the cardboard water resistance, increase its intensity, the strong paper board production water-proof adhesive of bounding force of enhancing productivity greatly simultaneously.

The present invention realizes above-mentioned purpose by following technical solution:

This paper board production water-proof adhesive, it mainly be by starch and water with 1: mixed (3-10) is added composition such as borax again and is constituted concrete component following (weight ratio): starch 10-25%, borax 1-20%, caustic soda 2-5%, stablizer 0.5-10%, glue crosslinking agent 0.5-10%, resin 0.02-8%, water 10-85%.

Adopt the cardboard MR adhesive advantage of above-mentioned formula constituent to be, under the prerequisite that does not increase cost, its anti-broken, water resistance index of its cardboard of producing improves greatly, show through testing contrast on the same group, adopt the bonding 40-50% of performance index cardboard of the cardboard of this tackiness agent, anti-broken raising 10%, water-fast protection against the tide obviously increases, so simultaneously under wet weather the production rate of cardboard improved more originally 50% or more than, thereby the cardboard folding of adopting this prescription to make, bounding force is strong, and stable performance has practical function preferably.

Embodiment

Principal feature of the present invention is that the ratio of borax increases greatly, thereby has improved the water resistance and the intensity of cardboard effectively, and by many groups test contrast, when the ratio of its borax reached 1-20%, the water resistance and the intensity of cardboard significantly increased.

Embodiment 1

Its component of cardboard MR adhesive of the present invention following (weight ratio): starch 18.5%, borax 6.5%, caustic soda 4%, stablizer 5%, glue crosslinking agent 5%, resin 1%, water 60%, mix above-mentioned component to be added on the board production getting final product.

Embodiment 2

By weight, starch 10%, borax 15%, caustic soda 5%, stablizer 8%, glue crosslinking agent 3%, resin 0.5%, water 58.5% mix stirring with above-mentioned component and get final product.

Stablizer in the present invention's prescription and glue crosslinking agent are the composition commonly used in the existing general production process, can be commercially available.

The cost of material of adhesive of the present invention is compared with existing formulation cost not to be increased, through experimental data Show that improve 25% or more than like product its storage period, in order to the corrugated board packing of producing Case intensity height, meet the instructions for use of the packing cases such as food, thereby overcome the easy moisture absorption of existing cardboard, Intensity is low, be difficult to the drawbacks such as wide popularization and application.

Claims

1, a kind of paper board production water-proof adhesive, comprise water and starch, it is characterized in that its concrete component is constructed as follows (weight ratio): 10-25% starch, 1-20% borax, 2-5% caustic soda, 0.5-10% stablizer, 0.5-10% glue crosslinking agent, 0.02-8% resin, 10-85% water.
