Abstract
The present invention relates to a starch adhesive mixed with zeolite powder to provide suitable absorption function for corrugated cardboards, and a method for making the adhesive. The adhesive comprises: corn starch as main ingredient, zeolite powder suitably mixed with said corn starch, water, and additives like caustic soda and borax. The corn starch is mixed with zeolite powder in an amount of zeolite powder being 20˜33% of the total weight of corn starch and the zeolite powder, and said adhesive is prepared and adjusted to have a lower gelation temperature. The present invention solves the problem that the initial adhesive strength of adhesive would decrease because of addition of the zeolite powder to the adhesive and would make the drying time longer and then deteriorating the initial adhesive strength. The present invention will make it more efficient and predictable for the mass production of the zeolite starch corrugated cardboards.
