Filed:

Apr 5, 2010

Appl. No.:

12/754236

Inventors:

Ben Wen - Horseheads NY, US
Jessica P. Zhang - Horseheads NY, US

Assignee:

United Environment & Energy LLC - Horseheads NY

International Classification:

B05D 1/12
B05D 1/36

US Classification:

427186, 427188

Abstract:

An adhesive product and method of making the product replaces asphalt in the manufacture of roofing shingles. The method comprises steps of forming a mixture of oil comprising fatty acids and a powdered catalyst operable to catalyze the polymerization of the oil; maintaining the oil to powdered catalyst weight ratio in the mixture between 1 to 0. 01 and 1 to 4. 9; heating the mixture to a reaction temperature greater than 100 degrees Centigrade; maintaining the reaction temperature for at least five minutes; and, injecting air into the mixture while maintaining the reaction temperature. In making a roofing shingle, the method includes additional steps of: applying the heated mixture to a fiberglass mat sheet from an upstream roll to form a tacky coated strip; and, adding a layer of granules to the tacky coated strip. The adhesive material of this method comprises polymerized oil and the powdered catalyst.

International Classification:

B05D 1/12

US Classification:

106246, 427186, 427188

Abstract:

A bio-based adhesive and method of making the adhesive replaces or serves as additives for asphalt, sealant, and polymers such as styrene-butadiene-styrene and atactic polypropylene in the manufacture of building or paving materials. The method includes steps of forming a mixture of oil comprising fatty acids group and optionally a powdered material; maintaining the oil-to-powdered-material weight ratio in the mixture between 1 to 0. 00001 and 1 to 20; heating the mixture to a reaction temperature greater than 55 degrees Centigrade; maintaining the reaction temperature until the oil is polymerized; and, injecting air into the mixture while polymerizing the oil. The adhesive of this method comprises a renewable polymer and the powdered material.

International Classification:

C09D 5/26
C09D 191/00
C09D 7/12

US Classification:

106244, 106264, 106310

Abstract:

A bio-based coating for a building automatically transmits or reflects heat gain from infrared sunlight. The coating is composed of bio-based polymerized oil and a catalyst that is also a thermochromic material. The catalyst reduces the temperature for polymerization of the oil to create a suspension that forms a hardened mixture when cooled below about 100 degrees Centigrade. The thermochromic properties of the catalyst are operable to switch the hardened mixture from transparent to reflective of infrared light when the temperature rises above a switching temperature in an approximate range of 18 degrees Centigrade to 35 degrees Centigrade. The method of using the coating involves spraying a hot bio-based coating on the roof surface and allowing it to cool. The method of making involves heating the suspension to a reaction temperature, holding at the reaction temperature, and, introducing an air flow through the mixture at the reaction temperature.
