Polyurethane artificial flowers and production method thereof

Abstract

The invention relates to the field of artificial plant technology, in particular to polyurethane artificial flowers and a production method thereof; the artificial flowers comprises blooms, stamens, flower poles and flower leaves which are all prepared by the following raw materials by weight percent: 41%-57% of polyether polyol, 1%-5% of amines catalyst, 1%-5% of crosslinking agent, 1% of foam stabilizer, 10% of foaming agent, 25%-30% of isocyanate, 2.5%-4% of anti-yellowing additive and 2.5%-4% of antioxidant through the following steps as follows: proportioning, pouring materials, closing dies, coloring, cutting and assembling; the preparation method is simple, the prepared polyurethane artificial flowers has the advantages of bright colors, good anti-buckling performance, difficult distortion, difficult yellow discolouration for putting for a long time, vivid image and lifelike feeling.

Description

Technical field: [0001] The invention relates to the technical field of artificial plants, in particular to a polyurethane artificial flower and a manufacturing method thereof. Background technique: [0002] In life, in order to beautify the living environment, people usually like to use plants to decorate their living space; and fresh plants, including flowers, trees and fruits, will become dry and lose their luster after a period of time due to the loss of water in the body and beautiful appearance, so people usually use artificial plants instead. These artificial plants not only can maintain a delicious appearance for a long time, but also have different shapes, and have become indispensable decorations for people to decorate the space; among them, artificial flowers and artificial plants are the most common. [0003] At present, people have also carried out a lot of research on artificial plants; from the initial rough plastic products to today's lifelike products, it i...

Problems solved by technology

[0003] At present, people have also carried out a lot of research on artificial plants; from the initial rough plastic products to today's lifelike products, it is mainly to show the beauty that is closest to natural plants; such as: Chinese Patent Publication No. CN1113129A, Invention The name is "Improved Artificial Plant"; it discloses an artificial plant prepared by using a new material expanded polyethylene (PVC) foam, although it has the same thickness, resilience and surface structure as the natural plant, but its feel is Still not realistic enough; simulation capabilities are still relatively limited
