Problems solved by technology

Auxiliary manufacturers such as Air Products, Evonik, and Momentive have also continuously introduced their low-volatility catalysts and silicone oils. However, due to the low amount of auxiliaries in the formula, although the foam VOC has improved to a certain extent, it is still far from meeting the requirements of an automobile OEM. a certain distance

Abstract

The invention relates to the technical field of foam materials, in particular to low-odor low-VOC (low volatile organic compounds) polyurethane high-elastic foam, characterized by comprising a polyolcomposition and an isocyanate; an equivalent ratio of the NCO content of the isocyanate to the OH content of the polyol composition is (70-120):100; the polyol composition includes a polyol, a crosslinker, a chain extender, a catalyst, silicone oil, an aldehyde remover, water, and other aids. Compared with the prior art, the PU (polyurethane) foam prepared herein has the advantages of low odor andlow VOC, is satisfactory to the requirements of automotive main unit manufacturers upon PU material odor and increasingly severe VOC issue, and is widely applicable to automotive interiors, furnitureproducts and fields having high VOC requirement.

Description

technical field [0001] The invention relates to the technical field of foam materials and preparation methods thereof, in particular to a low-odor, low-VOC polyurethane high-resilience foam. Background technique [0002] Polyurethane (PU) soft foam has the characteristics of light weight, high resilience, good comfort, durability, high sound insulation and shock absorption, and is widely used in automobile seats, backrests, headrests, armrests and sound and vibration isolation systems. and other applications. Along with people's increasing day by day to automobile quality and environmental protection requirement, the odor and volatile organic compound (VOC) in PU material receive more and more attention. In 2011, relevant national departments formulated GB / T 27630-2011 "Guidelines for Air Quality Evaluation in Passenger Cars", which stipulated that benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, Concentration requirements for VOCs such as acrol...
