Abstract

The invention relates to low-cost biomass polyurethane glue and a preparation process thereof. The preparation process comprises the following steps of: S1, feeding; S2, mixing and stirring; S3, heating; and S4, discharging. The invention further comprises a stirring device. According to the low-cost biomass polyurethane glue and the preparation process thereof, raw materials are placed in an outer container, and then a stirring motor is started to enable an upper stirring rod and a lower stirring rod which is in meshing transmission with the upper stirring rod through the gear to rotate, so that the raw materials can be uniformly and sufficiently mixed and stirred; a heating adjusting table and a heating rod can be conveniently connected to conduct electricity through linkage of conducting double loops and conducting rings, heating can be conducted after electricity conduction; and due to the fact that mixing is quite uniform, the heating rod acting along with stirring and mixing can also guarantee uniformity in the heating process, and therefore, the problems that the quality is common and the cost is increased when the biomass polyurethane glue is prepared and produced by adopting existing equipment are effectively solved.

Description

technical field [0001] The invention relates to the technical field of glue production, in particular to a low-cost biomass polyurethane glue and a preparation process thereof. Background technique [0002] Polyurethane glue is a glue containing urethane and isocyanate groups in the molecular chain. Due to the strong polar isocyanate and urethane groups, it has high reactivity and can be cured at room temperature, so it is suitable for metal, rubber, glass, ceramics, etc. , plastic, wood, fabric and leather and other materials have excellent adhesive properties. [0003] The main chain of polyurethane is very flexible. Its biggest feature is that it is resistant to shock, vibration and bending fatigue. It has high peel strength, especially excellent low temperature resistance, and is the best among existing glues. Therefore, it is widely used today. [0004] When the biomass polyurethane glue is produced and processed, it usually includes the process of stirring and mixing ...
