Abstract

The invention provides a bio-based polyurethane color paste. The bio-based polyurethane color paste is prepared from the following components in percentage by mass: bio-based polyether polyol, carbon dioxide-based polycarbonate polyether polyol, pigment powder and a bio-based dispersing agent. A preparation method of the bio-based polyurethane color paste comprises the following steps: adding the bio-based dispersing agent into the carbon dioxide-based polycarbonate polyether polyol and the bio-based soybean oil polyol, uniformly stirring, adding the pigment powder, dispersing for 15-25 minutes at the speed of 1000-2000 rpm, adding the grinding medium, grinding for 1.5-2.5 hours by using an oscillator, and discharging when the fineness is lower than 20 [mu]m. The fineness of the bio-based polyurethane color paste disclosed by the invention is controlled to be below 20 [mu]m, the fluidity is good, and the subsequent production efficiency is favorably improved; the color paste has good compatibility with a polyurethane composite material and is easy to disperse, the colored material is bright in color, the blackness of the black paste is good, and the product quality is greatly improved; in addition, the bio-based polyurethane color paste disclosed by the invention can meet the requirement of biodegradability.

Description

technical field [0001] The invention belongs to the field of polyurethane color paste, and in particular relates to a bio-based polyurethane color paste and a preparation method thereof. Background technique [0002] Color paste, as the name suggests, is a colored paste, which is developed by using different pigments through rigorous processing techniques such as surface treatment and surface wrapping of pigments. In nature, color pastes cooperate to dress up the whole world, ranging from clothing, daily necessities, toys, etc., to bridges, housing constructions, etc., all displaying colorful colors. [0003] Polyurethane materials are used in a very wide range, almost penetrate into all sectors of the national economy, and are widely used, and have become one of the indispensable materials. Polyurethane soft foam is mainly used in furniture, bedding and other household items, such as sofas and seats, back cushions, mattresses and pillows; polyurethane rigid foam is mainly ...
