Embodiment 1
[0040] A polyurethane production system such as figure 1 As shown, including: storage tank, reactor 200, metering system, vacuum system, temperature control system, filling system, compressed air system and control system,
[0041] The storage tank includes a raw material storage tank 110 and an auxiliary agent storage tank 120 . In this embodiment, there are seven raw material storage tanks 110, which respectively store polyols a, b, c, d, e, f, and g. It can be understood that the quantity of raw material storage tanks 110 and auxiliary agent storage tanks 120 can be flexibly designed according to production requirements, and only need to cooperate with corresponding metering systems.
[0042] The reactor 200 is provided with a feed port 210 , a feed port 220 and a vacuum port 230 . The reactor 200 can be a conventional reactor according to production requirements, such as a reactor with a motor-driven stirring paddle.
[0043] The metering system includes a metering tank...

Description
technical field [0001] The invention relates to the field of polymer material manufacturing, in particular to a polyurethane production system and method. Background technique [0002] The pouring heat insulating aluminum profile is formed by bonding the inner and outer parts of the aluminum profile into a whole with cast polyurethane heat insulating glue, so as to achieve the purpose of energy saving. Polyurethane thermal insulation adhesive is a high molecular polymer obtained by mixing two components, namely isocyanate and modified polyether polyol in a certain proportion, and undergoes a rapid crosslinking reaction. This kind of polymer is composed of soft segment and hard segment block, has relatively high mechanical strength and bonding strength, and can replace rivets, bolts and other forms for structural connection of aluminum profiles. [0003] However, this castable heat-insulating aluminum profile production process has very high requirements on the product stabi...
