Problems solved by technology

[0002] As rice seedling trays are needed in the process of rice seedling raising, and the elastomer in the rice seedling tray is an important part of the rice seedling tray, its fire safety is very important. In addition to the fire safety of the existing elastomers, It is also necessary to have a lightweight requirement to meet the requirements of the overall weight of the vehicle. In order to achieve this purpose, people have tried various materials as elastomer materials, but the pursuit of lightweight also reduces safety, and often occurs In the event of failure or accident, it is easy to cause a fire situation. Therefore, how to meet the demand for lightweight and have flame-retardant properties to ensure safety is a difficult technical problem to solve. In addition, the existing elastomer materials are not environmentally friendly and have a negative impact on the environment. Great impact and human harm

Abstract

The invention discloses an elastomer environment-friendly high-flame-resistance foaming material in a rice seedling culture plate and a preparation method thereof. The elastomer environment-friendly high-flame-resistance foaming material is prepared from isocyanate and combined material at mass ratio of 1:0.8. The combined material is prepared from the following materials in parts by weight: 68-75 parts of polyether JTP 330, 30-35 parts of polyether 982, 8-10 parts of polyether 210, 12-18 parts of polyether 1500, 2.9-3.5 parts of silicone oil AK 8805, 0.8-1.3 parts of catalyst A33, 0.6-1 part of catalyst A1, 3-3.8 parts of water and 35-40 parts of flame retardant TCPP. After the material and the method are adopted, the formula component is reasonable in collocation and the preparation method is proper, so that the prepared foaming material is high in flame resistance and is difficult to burn once meeting fire and the waterproof safety and personal safety are further ensured. Besides, the prepared elastomer is light in weight and can meet the weight requirements of vehicles. The used raw materials of the foaming material are environment-friendly raw materials, so that the matters toxic and harmful to human body are not released and the environmental protection requirement can be met.
