Problems solved by technology

[0004] The production process of the existing polyurethane adhesives is generally completed through the corresponding production line, but the traditional production line uses the traditional resistance indirect heating when heating, which not only leads to low heat utilization rate, but also in the process of cooling. Sometimes it is only cooled by a single air cooling method, the cooling effect is poor, it cannot meet the requirements, and it is easy to affect the product quality

Abstract

The invention discloses that the production line frame of a polyurethane adhesive production line is equipped with a material storage classification mechanism for raw material storage and classification, an automatic allocation mechanism for quantitative allocation of raw materials, and a forming mixing drum. The forming mixing drum is connected with a The forming and distributing components of the forming materials are quantitatively discharged, and the inside of the forming mixing drum is automatically mixed and stirred by an electric stirring mechanism. There are several main barrels and several secondary barrels on the production line frame, and a method for preparing a tackifier for water-based polyurethane adhesives is also disclosed, including the following steps: S100, raw material preparation and pretreatment; S200, raw material Mixing and stirring; S300, adding auxiliary materials; S400, degassing and cooling molding, mixing materials through combined heating and combined stirring methods to avoid uneven local reactions and effectively improve product quality.

Description

technical field [0001] The invention relates to the technical field of adhesive production, in particular to a water-based polyurethane adhesive production line and a method for preparing a tackifier. Background technique [0002] Polyurethane adhesive refers to the adhesive containing carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane. Polyisocyanate molecular chains contain isocyano groups (-NCO) and carbamate groups (-NH-COO-), so polyurethane adhesives exhibit high activity and polarity. It has excellent chemical adhesion to substrates containing active hydrogen, such as porous materials such as foam, plastic, wood, leather, fabric, paper, ceramics, and materials with smooth surfaces such as metal, glass, rubber, and plastic. [0003] Polyurethane adhesive is an important part of the rapidly developing polyurethane resin. It has excellent performance and ha...
