An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.

An environmentally friendly, formaldehyde-free, aqueous binder composition that includes a carbohydrate, a crosslinking agent, and a pre-reacted product of an alcohol or polyol and monomeric or polymeric polycarboxylic acid or polyglycerol is provided. The pre-reacted product may include glycerol and esters of citric acid such a monoglyceryl citrate, diglyceryl citrate, and triglyceryl citrate as well as other higher molecular weight citric acid-based esters. The inclusion of the pre-reacted product in the binder composition helps to speed the crosslinking reaction, induces faster water evaporation, decreases the viscosity of the binder, helps to reduce the amount of water needed for application of the binder, decreases tackiness, and helps to achieve a maximum vertical expansion of the insulation pack in the transfer zone. The binder composition may be used in the formation of insulation materials and non-woven chopped strand mats.

The invention discloses a method for preparing bond for corrugated boards by using potato residue as the raw material, which belongs to the technical field of preparing bonds. In the method, a bond with good performance and low cost for a corrugated board is obtained by using waste potato residue used for producing potato starch industrially as the main raw material, using superfine pulverizationby a colloid wet grinding method and the physical modification means of high-pressure steam treatment, combining oxidation modification treatment and adding a series of assistant agents. The main bonding properties of the prepared bond for the corrugated board are similar to those of a starch-based bond; the prepared bond conforms to the requirement of producing the corrugated board and can be widely applied to the production, the bonding and the like of the corrugated board; in addition, because the waste potato residue is used as the main raw material, the production cost is obviously reduced and the environmental pollution is effectively reduced.

The invention discloses a preparation method of corn starch adhesive through cannabis degummed waste liquor, which comprises the following steps: a, the preparation of carrier starch, b, the preparation of main starch, and c, the preparation of the corn starch adhesive. Corn starch is dissolved in warm water at 40 plus or minus 2 DEG C, and then catalyst FeSO4 is added. Cannabis degummed waste liquor is added till the pH value is 11.0 to 11.2, H2O2 is slowly added, and reaction is performed for 120min. Residual degummed waste liquor is added and stirred. Borax is dissolved in warm water at 40 plus or minus 2 DEG C, and then corn starch is added and uniformly mixed, and a small amount of tributyl phosphate is added, so as to perform defoaming. The carrier starch is added into the main starch while being stirred, stirring is performed for 30min, heat preservation is for 30min at 40 plus or minus 2 DEG C, and then a finished product is obtained after cooling. For producing 1 ton of adhesive, 166 Kg of corn starch, 260 Kg of degummed waste liquor, 0.22 Kg of FeSO4, 8.88 Kg of 30 percent H2O2, 2.33 Kg of borax, and 0.11 Kg of tributyl phosphate are required.
