Technical field
The invention belongs to amylan technical fields, more specifically more particularly to a kind of waterproof corn of environmentally friendly carton
Amylan.Meanwhile the invention further relates to a kind of preparation methods of the waterproof Corn Starch Glue of environmentally friendly carton.
Background technique
With the fast development of Chinese economy, chemical industry manufacturing field is also therewith forward, the usage amount of all kinds of adhesives also by
Year increases severely, and adhesive is many kinds of, is widely used in people's lives.Amylan viscose glue is as universal day
Right adhesive is increasingly used widely, this is based primarily upon two reasons, first is that starch resource is abundant, it is cheap, and
It is nontoxic free from extraneous odour, pollution-free；Second is that awarding the chemical products that petroleum is raw material with the increasingly reduction of petroleum resources and constituting
It threatens, so that many enterprises is made to find substitute one after another, and adhesive glue used in cardboard industry continues to use always sodium silicate, by
Big to the corrosivity of paper in its alkali content height, the cardboard produced is easy to get damp, deforms, is damaged, or even corrosion inner packing quotient
Product, and make the change of the structure, physical property and chemical property of starch by physico-chemical process or biochemical method, out
Existing a variety of denaturation cornstarch gluing glue with particular characteristic and purposes, the cornstarch adhesive glue have adhesive strength height,
It is light-weight, it is non-corrosive the features such as, to receive significant attention.
Since generally existing two common drawbacks, i.e. cardboard are dry fast in practical applications for general corn starch adhesive
Degree and the more traditional flower bulb alkaline error of stability, to influence service performance.
