Abstract
The invention discloses a formula of flame retardation epoxy resin, which comprises epoxy resin and an auxiliary additive. The auxiliary additive comprises a fire retardant, a cross-linking agent, a coupling agent, a filler, a dispersant and a mildew inhibitor; the fire retardant is aluminium hydroxide, the cross-linking agent is dicumyl peroxide, the coupling agent is amino propyl triethoxysilane, the filler is alumina powder, the dispersant is polyacrylamide, and the mildew inhibitor is phenol. According to the invention, the fire retardant and a plurality of auxiliary additives are added in epoxy resin, the flame retardation epoxy resin has good flame retardation performance, no halogen element is contained, and the flame retardation epoxy resin has the advantages of environmental protection and no pollution, simultaneously, the mutual cooperation of a plurality of additives can keep the physical and chemical performance of the flame retardation epoxy resin, and the physical and chemical performance of the flame retardation epoxy resin are increased at large degree.
Description
Technical field
The present invention relates to a kind of formula, be specifically related to a kind of formula of fire retarding epoxide resin.
Background technology
Epoxy resin cured product has good electrical insulation properties and physical and mechanical property, is widely used in the fields such as electrical equipment, electronics, mechanical industry.But its oxygen index only has 19.5 left and right, belong to inflammableness material.In recent years, each Application Areas is had higher requirement to its flame resistivity, and has carried out research extensively and profoundly.
The flame resistant method of epoxy resin cured product has two kinds of additive flame burning and reaction-type flame-retardingizations.Addition type is in epoxy resin composite, to add the various additives with flame retardant properties, makes material have flame retardant properties.Addition type is in epoxy resin composite, to add the various additives with flame retardant properties, makes material have flame retardant properties.The inexpensive easy row of addition type, for the main method of current application, but thereby other performances that affect epoxy resin are oozed out in the general easy migration of flame-retardant additive of adding, 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 is in epoxy resin, to introduce flame retarding construction, thereby makes fire retardant matter be difficult for migration, good flame retardation effect, but comparatively speaking, in reaction process, be not easy to control, easily cause the variation of other performances, cannot effectively control, thereby also be very restricted.
Summary of the invention
The object of the present invention is to provide the formula of the fire retarding epoxide resin that a kind of good flame retardation effect, environmental protection, physical and chemical performance are stable.
Technical scheme of the present invention is, a kind of formula of fire retarding epoxide resin, comprise epoxy resin and supplementary additive, described supplementary additive comprises fire retardant, linking agent, coupling agent, weighting agent, dispersion agent and mould inhibitor, and described fire retardant is aluminium hydroxide, and 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.
In a preferred embodiment of the present invention, 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%.
In a preferred embodiment of the present invention, 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%.
Of the present invention is a kind of formula of fire retarding epoxide resin, by adding in epoxy resin after fire retardant and multiple supplementary additive, make fire retarding epoxide resin there is flame retardant properties good, not halogen-containing element, environment friendly and pollution-free, meanwhile, physics, the chemical property that fire retarding epoxide resin itself is had that cooperatively interact of multiple additives do not change, and is improved to a great extent.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of formula of fire retarding epoxide resin, comprise 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.
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%, and aluminium hydroxide accounts for 5.2%, dicumyl peroxide accounts for 3.6%, and aminopropyl triethoxysilane accounts for 3.3%, and aluminum oxide powder accounts for 6.8%, polyacrylamide accounts for 2.4%, and phenol accounts for 2%.
Fire retardant can play and stop 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 intensity, cohesive force, electrical property, hydrophobicity, ageing resistance that makes material etc. significantly improves, and in reaction, improves speed of reaction, reduces production costs.
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 that prevents that fluoropolymer resin from being degraded by microbial attack
Of the present invention is a kind of formula of fire retarding epoxide resin, by adding in epoxy resin after fire retardant and multiple supplementary additive, make fire retarding epoxide resin there is flame retardant properties good, not halogen-containing element, environment friendly and pollution-free, meanwhile, physics, the chemical property that fire retarding epoxide resin itself is had that cooperatively interact of multiple additives do not change, and is improved to a great extent.
