とが出来る接着剤の改良が期待されて来た。(Conventional Technique vFI) Regarding adhesives used for gluing cardboard, sodium silicate was previously used, but now starch (cornstarch, wheat, etc.) is used as a raw material. Also, the conventional two-component adhesive C- can be used with a different carrierless corrugated adhesive, namely an improved adhesive consisting of a single-mixed layer adhesive lj1 composition, at a rate of at least 600 feet/min (180 m
The prior art is well-known for its special FIF No. 737404 corrugated board adhesive and method for producing the same, which can be bonded at machine speeds of up to 7 minutes). However, with the passage of time, there have been expectations for improvements in adhesives that can significantly speed up and streamline corrugated board production.

The purpose of this invention is to obtain a composition containing an adhesive component by chemically treating the ungelatinized starch itself so that it acts as a carrier, and by carrying out de-termination at a timely and appropriate manner.

A reaction mixture is obtained by mixing and reacting a slurry consisting of water and alkali with starch solids at a concentration of 5 to 5ON amount percent at a reaction temperature of approximately 10 to 50°C. It consists of a composition containing an adhesive component to which a reaction terminator is added so as to keep the gel point of partially swollen ungelatinized starch at about 48 to 56°C, and the resulting reaction mixture has a viscosity of 30 to 10,000 PS. This invention relates to adhesives for cardboard.

It is expected that productivity of cardboard will increase. Moreover, the excellent adhesion properties that shorten the manufacturing time are extremely effective in producing high-quality corrugated poles with less warpage and inclination than in the past.

Similar results can be obtained using yellow, waxy, corn, barley, and chemically modified oxidized starches, oxygen-modified starches, chemically derived starches, i.e., starch ethers, esters, and the like. Note that although caustic soda was used as the alkali, other alkaline substances may be used in the same manner. Furthermore, although boric acid was used as the reaction terminator, other acids such as aluminum sulfate, ferrous sulfate, ferric sulfate, etc. may also be used. Borax is precipitated as a neutral salt by the reaction between boric acid and caustic soda, but the missing amount is added to act as a viscosity stabilizer to increase initial adhesiveness. Also, the viscosity of the paste liquid of the reaction mixture is 300~? The most preferable adhesion condition is about 0OOP8 ◇Example 1 Water 28501Tt While stirring, cornstarch 1000/
