Problems solved by technology

[0005] However, in many processes for preparing vegetable oil polyols, most of them use petroleum-based products such as small molecule alcohols or amine compounds as ring-opening agents, which do not meet the requirements of the sustainable development strategy of green chemical industry, and the preparation process is relatively cumbersome, and the Most of the obtained vegetable oil polyols are only suitable for the production of polyurethane rigid foam materials, and are not suitable for the production of polyurethane soft foam materials.

Abstract

The invention discloses vegetable oil polyurethane soft foam polyol, and a preparation method and an application thereof. The method comprises the following steps: (1) carrying out ring-opening reaction on epoxy vegetable oil, benzoyl formic acid, a basic catalyst and an inert solvent in a first microchannel reactor of a microchannel reaction device to obtain vegetable oil polyol; and (2) carryingout addition polymerization reaction on the vegetable oil polyol obtained in the step (1), epoxy propane and an inert solvent in a second microchannel reactor of the microchannel reaction device to obtain the vegetable oil polyurethane soft foam polyol. The obtained vegetable oil polyurethane soft foam polyol is novel in structure and can completely replace the traditional petrochemical polyol tobe applied to the preparation of polyurethane foam materials.

Description

technical field [0001] The invention belongs to the technical field of chemical materials and production thereof, in particular to a vegetable oil polyurethane soft foam polyol and its preparation method and application, and the vegetable oil polyurethane soft foam polyol synthesized by the invention is suitable for preparing polyurethane materials. Background technique [0002] Polyurethane is a polymer with repeating structural units of urethane segments produced by the reaction of isocyanate and polyol. Polyurethane products are divided into two categories: foamed products and non-foamed products. Foamed products include soft, rigid, and semi-rigid polyurethane foams; non-foamed products include coatings, adhesives, synthetic leather, elastomers, and elastic fibers. Polyurethane materials have excellent performance, wide range of uses, and many types of products, among which polyurethane foam is the most widely used. Polyurethane soft foam refers to soft polyurethane fo...
