Abstract

The invention belongs to the field of chemical engineering, and particularly relates to a polyurethane simulation flower and a preparation method thereof. The polyurethane simulation flower is prepared by a component A and a component B, wherein the component A comprises polyether polyol whose functionality degree is 3 and molecular weight is 6,000, polyether polyol whose functionality degree is 3 and molecular weight is 8,000, water, a foam stabilizing agent, an amine catalyst, a cross-linking agent, a chain extender and a diluent, and the component B comprises a modified black material. According to the polyurethane simulation flower, the processing technology is simple, the production efficiency is high, a pedal model with large radian can be made vivid, essence can be added into the simulation flower made of the polyurethane material during the manufacturing process, accordingly, the flower has fragrance of a true flower, and the color solidification degree of the simulation flower is better than that of a silk flower; the simulation flower has good hand feeling and touches like the true flower, and no trace is left after touching; and the production efficiency is high, the energy consumption is low, and the product is washable and has the advantages of high simulation degree, absence of scrap falling on surfaces of the flower and leaves and the like. The invention further provides the preparation method of the polyurethane simulation flower, the technology is reasonable, and the preparation method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a polyurethane artificial flower and a preparation method thereof. Background technique [0002] Polyurethane artificial flowers are flowers made of polyurethane material on the market, which can be faked. Moreover, this "real" is not only visually true, but also very similar to real flowers in terms of touch and smell. The technology of artificial flowers is also constantly developing and changing. Materials such as paper, cloth, silk, yarn, and velvet are constantly used in the production of artificial flowers. More real and more similar can be said to be the goal of artificial flowers. With the application of new materials, this goal is being practiced. [0003] Polyurethane artificial flowers have the following advantages: Polyurethane material artificial flower process: petals are extruded directly through the mold like toothpaste, and then cut, colored, glued, ...
