Abstract

The invention belongs to the technical field of polyurethane and particularly relates to polyurethane composition for a car steering wheel and a preparation method of the polyurethane composition. Thepolyurethane composition is prepared from a component A and a component B in the weight ratio being 100:(40-50), wherein the component A is prepared from raw materials in parts by weight as follows:60-70 parts of polyether polyol, 30-40 parts of polyether ester polyol, 0.1-1 part of a foam stabilizer, 5-10 parts of a chain extender, 0.5-1 part of a catalyst, 0.8-1.2 parts of a foaming agent, 1.5-4 parts of an opening agent and 2-3 parts of a flame retardant; the component B is prepared from raw materials in parts by weight as follows: 7-10 parts of polyether ester polyol, 2-4 parts of propylene glycol, 20-30 parts of MI, 15-20 parts of pure MDI and 35-45 parts of crude MDI. Polyether ester polyol is taken as a raw material, so that the polyurethane composition has the performance of polyester and can provide the flexibility of polyether, and the overall performance and comfort of a product are improved; a non-metal catalyst is used, and harm to human bodies is reduced; sodium hydroxide nanofiber can have a certain flame retardant effect. The preparation method is scientific, reasonable and simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of polyurethane, and in particular relates to a polyurethane composition for an automobile steering wheel and a preparation method thereof. Background technique [0002] In recent years, the rapid development of the market economy has driven the progress of the automobile industry, and at the same time the progress of the automobile industry has stimulated market demand. Environmental protection and high quality have become synonymous with the present. With the rapid improvement of living standards, there is a high demand for quality of life. As a common means of transportation for the common people, cars will inevitably become a hot spot. Steering wheels, as an important part of cars, are more concerned focus. The traditional car steering wheel has a cloth type and a leather type, which has a series of problems such as poor hand feeling and easy sweat absorption. Contents of the invention [0003] The o...
