Embodiment Construction

[0023] The present invention is further illustrated by the following examples, but the present invention is not limited to the following examples. Unless otherwise specified, all the amounts given in "parts" and "percentage" should be understood as being by weight. The following materials were used to produce the polyurethane foams of the examples:

[0024] Table 1 Brief Introduction of Polyurethane Raw Materials

[0025]

[0026] The preparation method of biomass-based flame-retardant polyurethane soft sponge foam comprises the following steps: (1) flame-retardant epoxy soybean oil polyol A and polymer polyol, catalyst, blowing agent, foam stabilizer, flame retardant and isocyanate components; each component listed in the following table 2 is transported to the foaming machine head by the weight ratio in table 2 through a metering pump, and after high-speed stirring, the cloth is evenly distributed on the kraft paper of the continuous foaming production line to produce A ...

Abstract

The invention discloses biomass-based flame-retardant polyurethane soft sponge foams and a preparation method thereof. The foams are characterized by being environmental-friendly renewable biomass-based flame-retardant polyurethane soft sponge foams which are prepared by mixing flame-retardant modified epoxy soybean oil polyhydric alcohols (a), and polymer polyhydric alcohols (b) as main raw materials, mixing with a isocyanate component (c), foaming and polymerizing under the action of a reactive or low-odor catalyst, a physical and/or chemical foaming agent, a foam stabilizer or a flame retardant. As the biomass-based flame-retardant polyurethane soft sponge foams disclosed by the invention are produced from renewable biomass raw materials, the dependency of foam synthetic products on petroleum and coal resources is reduced, the product price is stabilized, and the purposes of environment protection and low carbon are also achieved.

Description

technical field [0001] The invention relates to a soft polyurethane sponge foam and a preparation method thereof. Background technique [0002] Polyurethane flexible foam is referred to as soft foam, commonly known as sponge, which refers to soft polyurethane foam with certain elasticity. It is mainly used for furniture cushions, vehicle seat cushions and various soft cushion laminated composite materials. [0003] The main raw material of the polyurethane soft sponge foam in the prior art is a product extracted from petroleum, which is a non-renewable resource, and its processing and production process is complicated, the cost is high, and it pollutes the environment. With the continuous reduction of oil reserves, the international oil price and petrochemical products are rising steadily, the polyurethane flexible foam produced with polyols produced from renewable resources such as renewable biomass and recycled vegetable oil as raw materials has a broad market Prospects. ...
