Environment-friendly foam material with high flame retardance for shells of agricultural spraying machines and method for preparing environment-friendly foam material

Abstract

The invention discloses an environment-friendly foam material with high flame retardance for shells of agricultural spraying machines and a method for preparing the environment-friendly foam material. The environment-friendly foam material comprises isocyanate and combination materials. A mass ratio of the isocyanate to the combination materials is 1:1.8. The combination materials comprise, by weight, 45-55 parts of polyether 403, 25-35 parts of polyether 635, 15-25 parts of polyether 3450, 10-15 parts of polyether 1500, 15-25 parts of polyether 943, 2.5-3 parts of silicone oil 8804, 1.2-1.4 parts of catalysts HP300, 1-1.5 parts of catalysts HP224, 3.5-4.6 parts of water and 38-42 parts of flame retardants TCEP. The environment-friendly foam material and the method have the advantages that components of the environment-friendly foam material in a formula are reasonably matched with one another, the method is appropriate, accordingly, the environment-friendly foam material prepared by the aid of the method is high in flame-retardant property and is difficult to combust when in contact with fire, and the fireproof safety and the personal safety can be guaranteed; the manufactured shells of the spraying machines are quite light, and carrying and shifting requirements can be met; raw materials for the environment-friendly foam material are environment-friendly raw materials, accordingly, the environment-friendly foam material is free of release of substances which are toxic and harmful for human bodies, and environmental protection requirements can be met.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to an environment-friendly high flame-retardant foaming material for an agricultural sprayer shell and a preparation method thereof. Background technique [0002] After agricultural planting, pesticides need to be sprayed, and spraying pesticides generally requires the use of sprayers to spray pesticides. The shell of the existing agricultural sprayer is an important part of the agricultural sprayer, and its fire safety is very important. In addition to fire safety, the shell of the existing sprayer also needs to have lightweight requirements to meet the requirements of handling and movement. In order to achieve this purpose, people have tried various materials as the shell material of the sprayer, but in The pursuit of light weight also reduces safety, and it is often easy to cause fires when encountering failures or accidents. Therefore, how to meet the need...

[0002] After agricultural planting, pesticides need to be sprayed, and spraying pesticides generally requires the use of sprayers to spray pesticides. The shell of the existing agricultural sprayer is an important part of the agricultural sprayer, and its fire safety is very important. In addition to fire safety, the shell of the existing sprayer also needs to have lightweight requirements to meet the requirements of handling and movement. In order to achieve this purpose, people have tried various materials as the shell material of the sprayer, but in The pursuit of light weight also reduces safety, and it is often easy to cause fires when encountering failures or accidents. Therefore, how to meet the needs of light weight and have flame-retardant properties to ensure safety is a difficult technical problem to solve , In addition, the shell material of the existing sprayer is not environmentally friendly, which has a great impact on the environment and harm to the human body
