Description
Technical field
The present invention relates to composition epoxy resin field more particularly to a kind of high tenacity, halogen-free flameproof vacuum diversion epoxies
Resin combination and preparation method thereof, more particularly to electrotechnical, electronic, aerospace, new energy, rail traffic, sports equipment etc.
There is the halogen-free flame retardant epoxy resin composition and preparation method thereof that high flame-retardant property requires to material.
Background technology
There is epoxide resin material good corrosion resistance, adhesive property, low-shrinkage to have compared with metal material
Have the advantages that light weight, intensity are high.But since the chemical constitution of epoxy resin itself determines its impact flexibility, elongation at break
It is poor with flame retardant property；It should be further noted that the composition epoxy resin gel time of domestic production at present is shorter,
And a large amount of solid metal hydroxide fire retardant of halogen-free fire-retardant epoxy resin generally use, this based flame retardant do not dissolve in resin
System, and the viscosity of resin system can be caused larger, it is only applicable to manual pasting forming process to limit it, is not met by big
The vacuum diversion forming requirements of type composite material, such as：The manufacture of wind turbine blade, railway air conditioner product, so scientific research personnel
By the modification to composition epoxy resin to obtaining better performance product.
To improve the flame retardant property of epoxy resin-base composite material, it usually needs be added in resin system and contain halogen flame retardant
Agent and/or halogen-free flame-retardant.Halogen-containing flame retardant will produce toxic, carcinogen in Pintsch process and burning.And Halogen
Fire retardant not will produce the carcinogens such as polybrominated dibenzo-furan and more bromo dibenzo dioxanes then in burning, be referred to as nothing
Public hazards fire retardant.It can be seen that a novel, strong mechanical performance of research and development, environment amenable halogen-free fire-retardant epoxy resin material
Material has very important realistic meaning.National 13 planning outlines are complied fully with for the research and development of such Halogen resin material
The Major Strategic Demands such as the environmentally protective industry of development of middle proposition, material.
Chinese patent 201010602588.X discloses one kind by epoxy resin, reaction diluent and curing agent (amine and miaow
Azole compounds) composition epoxy-resin systems, the gel time at 23 DEG C is only 10-60min, is not suitable for hand paste and water conservancy diversion
Large component.It is to be noted that the toxicity of the accelerating agent phenolic compound described in the patent of invention is very big, with cell original
Protein chemically reacts in slurry, and then invades nerve center, stimulates spinal cord, eventually results in systemic toxicity profiles.
Chinese patent CN105315620A discloses a kind of epoxy resin enhancing lamination insulated type material.The fire retardant is big
Amount has used inorganic combustion inhibitor, therefore cannot achieve vacuum diversion.And it is using heat pressing process.Heat pressing process equipment at
This costliness, high processing costs, high energy consumption are not suitable for the rapid processing of short product of potential period.
Therefore, for a kind of solid metal hydroxide fire retardant and nontoxic or less toxic of capable of substituting completely of searching (1)
Sex flame retardant is applied to composition epoxy resin, and (2) have high impact toughness and the preferable epoxy of elongation at break, flame retardant property
Resin combination；(3) there is suitable gel time and exothermic peak temperature；(4) it is adapted to vacuum diversion moulding process, there is weight
The realistic meaning wanted.

In suitable phosphonate ester is not added, so affecting its flame retardant property, flame retardant rating can only achieve UL94V-1.
(2) high tenacity of patent proposition of the present invention, halogen-free flame retardant epoxy resin composition embodiment 1-6 are due to adding foot
The novel phosphonate fire retardant enough measured, therefore DIN5510-2 can be met：S4 in 2009 standards, SR2, the fire protection requirement of ST2.
(3) high tenacity of patent proposition of the present invention, halogen-free flame retardant epoxy resin composition can be used for vacuum diversion technique.Its
The density of manufactured resin-base glass fibre (unidirectional cloth) composite material is usually less than the epoxy resin lamination insulation that filler is added
Proximate matter, also well below the density of steel.It can be seen that there is light weight according to laminate made of patent of the present invention, use
The advantages that more convenient.
(4) epoxy resin (unidirectional cloth) composite materials property made of patent of the present invention is higher, tensile strength and curved
Qu Qiangdu is up to 890MPa and 997MPa respectively.It can be seen that much according to laminate mechanical property made of patent of the present invention
Higher than steel.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
