Abstract

The invention provides premixing equipment for a polyurethane polyol multi-component formula. The premixing equipment comprises a polyether raw material storing system, a plurality of auxiliary material storing and conveying systems, a manual test mixing device, a mixing metering system and a mixed raw material storing and conveying system. A first conveying pump of the polyether raw material storing system is respectively connected with a manual test mixing tank of the manual test mixing device and a mixing metering tank of the mixing metering system; auxiliary material conveying pumps of the auxiliary material storing and conveying systems are respectively connected with the manual test mixing tank of the manual test mixing device; an auxiliary material A metering tank, an auxiliary material B metering tank and an auxiliary material C metering tank of the mixing metering system are respectively connected with the corresponding auxiliary material conveying pump of the auxiliary material storing and conveying systems, and the pipelines of the auxiliary material A metering tank, the auxiliary material B metering tank and the auxiliary material C metering tank are respectively provided with a flow proportional valve; and a mixing tank conveying pump of the mixing metering system is connected with a material storage tank of the mixed raw material storing and conveying system through a pipeline. According to the premixing equipment provided by the invention, automatic burdening can be performed according to the formula, therefore, the manpower is saved, and the polyurethane production cost is reduced.

Description

technical field [0001] The invention relates to a polyurethane production equipment, in particular to a polyurethane polyol multi-component formula premixing equipment. Background technique [0002] With the rapid development of my country's automobile industry and the continuous improvement of humanized requirements for car seats, how to effectively control production costs while improving product comfort and durability has become a research topic for major automotive interior parts manufacturers. In the past production mode, polyurethane raw material suppliers mixed various auxiliary raw materials (such as water, catalysts, crosslinking agents, silicone oil, etc.) in polyether polyol raw materials according to a certain formula and then sold them to automotive interior parts manufacturers. Such raw materials Raw materials that can satisfy production but are not the most suitable for our company's products. With the improvement of customer requirements, various manufacture...
