Abstract

The invention provides a low-odor low-VOC foaming raw material and a material mixing process thereof. The preparation method of the foaming raw material comprises the following steps: adding 3.2-4 parts of deionized water into a mixing tank, conveying 100 parts of polyether polyol EP -3600 to the mixing tank through a feeding pump, and uniformly stirring; adding 2-2.5 parts of a pore-forming agent, 0.5-1.2 parts of a foam stabilizer, 0.2-0.4 part of a curing agent, 0.5-1 part of a low-odor catalyst, 0.1-0.3 part of diaminopropane and 0.6-1.0 part of diethanolamine into a raw material barrel, feeding the mixture into an auxiliary material stirring tank through a feeding pump, uniformly stirring, adding the uniformly mixed auxiliary materials into the mixing tank in the step (2), and uniformly mixing in the mixing tank at the rotating speed of 120-500 r / min to prepare the low-odor low-VOC foaming raw material. The method disclosed by the invention has the advantages that the odor is prevented from being too large, and the reaction type catalyst which is low in molecular weight, low in odor and is low in volatilization is used, so that the odor of the VOC (volatile organic compounds)is prevented from being too large.

Description

technical field [0001] The invention relates to a foaming material for an automobile interior decoration, in particular to a low-odor and low-VOC foaming raw material and a mixing process for the automobile interior decoration foaming material. Background technique [0002] The comfort of automotive interior parts has become an important issue in the field of automobile research and development. In the past, my country only focused on the functionality and reliability of automotive interior parts and legally controlled them. However, with my country's entry into the WTO, the consumption level It will also continue to improve, and future consumer and legal controls will pay more attention to comfort and safety. [0003] The headrest of the car seat must meet the safety function, and it can effectively protect the head and neck passively when the passenger has a traffic accident. In addition, passengers have higher and higher requirements for the comfort of the headrest. At pr...
