Problems solved by technology

However, polydicyclopentadiene is composed of hydrocarbons containing unsaturated double bonds, which is very flammable, which limits its application in many fields such as electronic appliances and decorative materials.
[0003] In the existing technology, the flame retardant performance of polydicyclopentadiene is often achieved by adding a high proportion of flame retardants. However, it has been found that the addition of a high proportion of flame retardants will affect the mechanical and physical properties of polydicyclopentadiene. performance, when it is used in the automotive field or the aerospace industry, it will cause safety hazards due to the loss of its mechanical properties

Abstract

The invention provides an environment-friendly and flame-retarding polydicyclopentadiene material. The environment-friendly and flame-retarding polydicyclopentadiene material is characterized by beingprepared from the following components in percentage by weight: 75 percent to 85 percent of dicyclopentadiene, 0.01 percent to 1 percent of a catalyst, 10 percent to 22 percent of a flame retardant,0.2 percent to 5 percent of a coupling agent, 0.1 percent to 3 percent of an anti-ageing auxiliary agent and 0.1 percent to 3 percent of an ultraviolet absorbent, wherein the catalyst is selected fromone or more of ruthenium alkyidene carbine catalysts; the flame retardant is a compound mixture of modified aluminum hydroxide and / or modified magnesium hydroxide and one or more of flame retardantsincluding an organic silicon type flame retardant, a melamine phosphate, a phosphate type flame retardant and pentaerythritol. The environment-friendly polydicyclopentadiene material provided by the invention has good performance and has a good flame-retarding function.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an environment-friendly flame-retardant polydicyclopentadiene material and a preparation method thereof. Background technique [0002] Polydicyclopentadiene material has excellent physical and mechanical properties and good chemical properties, and its raw material dicyclopentadiene has a low viscosity (about 0.3Pa s), and can be quickly ring-opened and polymerized under the introduction of a little heat and a catalyst , the reaction rate is very fast, so dicyclopentadiene is particularly suitable for reaction injection molding (RIM), especially for the production of large structural parts. However, polydicyclopentadiene is composed of hydrocarbons containing unsaturated double bonds and is very flammable, which limits its application in many fields such as electronic appliances and decorative materials. [0003] In the existing technology, the flame retard...
