Abstract
The invention discloses an expanded starch adhesive which is prepared from the following components in parts by weight: 80-100 parts of expanded corn starch, 1.5-4 parts of bentonite, 0.5-1 part of borax, 5-8 parts of sodium tripolyphosphate, 1-3 parts of sodium benzoate, 5-10 parts of calcium chloride, 8-15 parts of alum and 1-3 parts of potassium permanganate. The invention also discloses a preparation method of the adhesive. The expanded starch adhesive uses the expanded corn starch as the main raw material, has the advantages of favorable initial adhesive force and high strength, and is easy to store and convenient to use; the bentonite is added to enhance the solid content, reduce the moisture and obviously enhance the drying rate; the borax is added, so that the prepared adhesive forms a complexing action while adding water so as to form a network crosslinked structure; and the sodium tripolyphosphate is added to enhance the adhesive strength.
