Abstract
The invention relates to flame-retardant epoxy resin. The flame-retardant epoxy resin is characterized by comprising an epoxy resin body and auxiliary additives, wherein the auxiliary additives comprise a fire retardant, a cross-linking agent, a coupling agent, a filling agent, a dispersing agent and a mildew preventive, the fire retardant is aluminum hydroxide, the cross-linking agent is dicumyl peroxide, the coupling agent is 3-aminopropyltriethoxysilane, the filling agent is alumina powder, the dispersing agent is polyacrylamide and the mildew preventive is phenol. According to the flame-retardant epoxy resin, the fire retardant and the multiple additives are added to the epoxy resin body, so that the flame-retardant epoxy resin has the advantages of being good in flame-retardant property, free of halogen elements, environmentally friendly and free of pollution. Meanwhile, the multiple additives cooperate mutually, so that physical performance and the chemical performance of the flame-retardant epoxy resin are not changed and are greatly improved.
Description
Technical field
The present invention relates to a kind of fire retarding epoxide resin.
Background technology
The flame resistant method of epoxy resin cured product has additive flame burning and reaction-type flame-retardingization two kinds.Addition type is in epoxy resin composite, add the various additive with flame retardant properties, makes material have flame retardant properties.Addition type is in epoxy resin composite, add the various additive with flame retardant properties, makes material have flame retardant properties.Addition type is inexpensive easy, for the main method of current application, but the flame-retardant additive added generally easy migration oozes out thus affects other performances of epoxy resin, and the fire retardant that addition type uses is mostly halogen flame, its flame retarding efficiency is higher, but being but subject to environmental requirement more and more limits.Response type introduces flame retarding construction in the epoxy, thus fire retardant matter is not easily moved, good flame retardation effect, but comparatively speaking, be not easy to control in reaction process, easily cause the change of other performances, effectively cannot control, thus also be very restricted.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of fire retarding epoxide resin.
Described a kind of fire retarding epoxide resin, it is characterized in that comprising epoxy resin and supplementary additive, described supplementary additive comprises fire retardant, linking agent, coupling agent, weighting agent, dispersion agent and mould inhibitor, described fire retardant is aluminium hydroxide, linking agent is dicumyl peroxide, and coupling agent is aminopropyl triethoxysilane, and weighting agent is aluminum oxide powder, dispersion agent is polyacrylamide, and mould inhibitor is phenol.
Described fire retarding epoxide resin, it is characterized in that the weight proportion scope of each composition in the formula of described fire retarding epoxide resin is that epoxy resin accounts for 73.6%-79.8%, aluminium hydroxide accounts for 4.4%-5.7%, dicumyl peroxide accounts for 2.6%-3.9%, aminopropyl triethoxysilane accounts for 2.8%-3.4%, aluminum oxide powder accounts for 6.4%-7.1%, and polyacrylamide accounts for 2.3%-3.5%, and phenol accounts for 1.7%-2.8%.
Described fire retarding epoxide resin, it is characterized in that the weight proportion scope of each composition in the formula of described fire retarding epoxide resin is that epoxy resin accounts for 76.7%, aluminium hydroxide accounts for 5.2%, dicumyl peroxide accounts for 3.6%, aminopropyl triethoxysilane accounts for 3.3%, aluminum oxide powder accounts for 6.8%, and polyacrylamide accounts for 2.4%, and phenol accounts for 2%.
After the present invention passes through to add fire retardant and multiple supplementary additive in the epoxy, fire retarding epoxide resin is made to have flame retardant properties good, not halogen-containing element, environment friendly and pollution-free, simultaneously, the physics that the cooperatively interacting of multiple additives makes fire retarding epoxide resin itself have, chemical property do not change, and are improved to a great extent.
Embodiment
The present invention includes epoxy resin and supplementary additive, described supplementary additive comprises fire retardant, linking agent, coupling agent, weighting agent, dispersion agent and mould inhibitor, described fire retardant is aluminium hydroxide, linking agent is dicumyl peroxide, coupling agent is aminopropyl triethoxysilane, weighting agent is aluminum oxide powder, and dispersion agent is polyacrylamide, and mould inhibitor is phenol.
Further, in the formula of described fire retarding epoxide resin, the weight proportion scope of each composition is that epoxy resin accounts for 73.6%-79.8%, aluminium hydroxide accounts for 4.4%-5.7%, dicumyl peroxide accounts for 2.6%-3.9%, aminopropyl triethoxysilane accounts for 2.8%-3.4%, aluminum oxide powder accounts for 6.4%-7.1%, and polyacrylamide accounts for 2.3%-3.5%, and phenol accounts for 1.7%-2.8%.
Further, in the formula of described fire retarding epoxide resin, the weight proportion scope of each composition is that epoxy resin accounts for 76.7%, aluminium hydroxide accounts for 5.2%, dicumyl peroxide accounts for 3.6%, aminopropyl triethoxysilane accounts for 3.3%, aluminum oxide powder accounts for 6.8%, and polyacrylamide accounts for 2.4%, and phenol accounts for 2%.
Fire retardant can play and stops or suppress its incendiary effect in plastics; Linking agent can promote the formation with telomerized polymer molecular chain, significantly improves thermotolerance, resistance to chemical corrosion, dimensional stability, weathering resistance and mechanical property etc.; Coupling agent can make additive and polymkeric substance combine closely, and the intensity of material, cohesive force, electrical property, hydrophobicity, ageing resistance etc. is significantly improved, and improves speed of reaction in the reaction, reduces production cost; Weighting agent can improve the performance of polymkeric substance and reduce costs; Dispersion agent can promote various subsidiary material homodisperse auxiliary agent in resin, and the properties of resin itself is not changed; Mould inhibitor is a kind of stabilizing additive preventing fluoropolymer resin from being degraded by microbial attack.
After the present invention passes through to add fire retardant and multiple supplementary additive in the epoxy, fire retarding epoxide resin is made to have flame retardant properties good, not halogen-containing element, environment friendly and pollution-free, simultaneously, the physics that the cooperatively interacting of multiple additives makes fire retarding epoxide resin itself have, chemical property do not change, and are improved to a great extent.
