Problems solved by technology

[0010] In order to overcome the deficiencies in the prior art, the present inventors have carried out intensive research and provided a microwave curing equipment and curing process for the production of insulation boards. The polar molecules of the adhesive are activated by microwaves to improve the molecular activity and the binding force between the components. By partitioning the microwave curing equipment according to product characteristics, the problem of uneven curing and poor quality of low thermal conductivity materials is solved, the thermal insulation performance and mechanical properties (tensile strength of the vertical board surface) of the insulation board are improved, and the curing time is shortened. The curing pressure is reduced, the curing temperature is reduced, the use of curing aids is reduced, energy utilization is improved, energy consumption is greatly reduced, and cost is reduced, thereby completing the present invention

Abstract

The invention provides microwave curing equipment and curing process for the production of insulation boards. The curing process is implemented by the microwave curing equipment. The microwave curingequipment comprises a microwave unit, a conveyor belt unit, an air outlet system and a hot air system, wherein the microwave unit is of a cavity structure, the conveyor belt unit carries materials after spraying an adhesive into a microwave unit cavity, and the adhesive is heated and cured through microwave by the microwave unit; the air outlet system communicates with the microwave unit, steam generated by microwave heating is discharged through an air outlet pipeline to the hot air system, and after the steam is burned by the hot air system, the hot air generated after burning is sent back to the microwave unit. According to the microwave curing equipment and curing process, the problem of low heating efficiency of low thermal conductivity materials by using traditional heat sources is solved, the microwave heating method is utilized, the energy utilization rate is greatly increased, the curing cycle of composite materials is shortened, and thus mass assembly line production is possible.

Description

technical field [0001] The invention belongs to the field of thermal insulation board production and manufacturing processes, and particularly relates to a microwave curing device and a curing process for the production of thermal insulation boards. Background technique [0002] The emergence of the new type of insulation board solves the dilemma that the fireproof materials on the market are not insulated and the insulation materials are not fireproof, and at the same time, it has the characteristics of green and non-toxic. With the gradual maturity and stability of the new insulation board technology, the market demand has become more and more obvious, and the mass production and supply of new insulation boards has become an imminent problem. [0003] The new thermal insulation board composite material is a new material and new technology, and its core feature is that the thermal conductivity is very low. The curing process is involved in the production process of the new...
