Description
Technical field
The present invention relates to coating technical field of flame retardant, and in particular to a kind of DOPO base expanding fire retardant.
Background technique
Wiring board is the substrate for carrying electronic component, it is bound fraction indirect material on the basis of direct material, is led to
Cross what the tool of production completed the process.Wherein, direct material, which refers to, is directly used on product in production or directly connects with product
The main material of touching；Indirect material refers in production indirectly using the secondary material on product or with product mediate contact.
In wiring board production there are three types of most important direct materials, i.e. substrate, prepreg and copper foil.Substrate (core/laminte) is
It is suppressed by prepreg and copper foil.Prepreg is then to combine different strengthening material and filler system by resin, glass cloth
It makes.
On requiring fire-retardant electronic equipment, it is also necessary to which fire-retardant circuit board, these circuit boards are all to be coated with flame-retarded resin
Laminate.Epoxide resin material is because having many special energy outstanding, such as preferable thermal stability, insulating properties, adhesion, anti-corruption
Corrosion and good mechanical property are widely used in the fields such as electronics, electric appliance, and then become currently the most important ones electron chemistry
Material it.However, its oxygen index (OI) is not high, and only 20% or so, belong to flammability substance, its flame retardant property need to usually be changed
Good raising.Common flame resistant method first is that introducing the halogens such as chlorine, the bromine with fire retarding effect in the epoxy to mention
The flame retardant property of high epoxy resin solidfied material.In recent years, people have carried out big in terms of the anti-flammability for improving epoxide resin material
Amount and in-depth study.
9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, abbreviation DOPO contain P-H key in structure, to alkene
Hydrocarbon, epoxide and the great activity of carbonyls can react and generate many derivatives.DOPO and its derivative are due to molecule
Contain cyclohexyl biphenyl, phenanthrene ring, O=P-O key in structure, so there is stronger flame retardant property than common organophosphorus ester.By
Saito reported its synthetic route in 1972 for the first time.DOPO and its derivative can be used as response type and additive flame retardant, close
At fire retardant Halogen, smokeless, nontoxic, do not migrate, flame retardant property is lasting.While improving the flame retardant property of material, not shadow
Ring the mechanical performances such as the mechanical strength of material.It can be used for the multiple materials such as polyamide, linear polyester, polyurethane, epoxy resin
Flame retardant treatment, foreign countries are widely used in the fire-retardant of materials such as pressurized layer, circuit board in plastics for electronics, brass.
Summary of the invention
In view of the above deficiencies, the object of the present invention is to provide a kind of formulas rationally, and the good DOPO base of stability expands resistance
Fire agent.When being added into epoxy resin coating system, there is excellent flame retardant effect, when flame retardant agent content reaches 4%
When, solidfied material can achieve UL94, and V-0 grades.
To achieve the above object, the technical solution provided by the present invention is:
A kind of DOPO base expanding fire retardant, is made of the raw material of following mass percent:
As a preferred solution of the present invention, it is made of the raw material of following mass percent:
As a preferred solution of the present invention, it is made of the raw material of following mass percent:
As a preferred solution of the present invention, the graphene containing DOPO group is that graphene surface is grafted with 1
A or multiple DOPO groups.
As a preferred solution of the present invention, the dispersing agent is hyperbranched propenoic acid ester polymer.Specifically, this hair
Bright dispersing agent can be Guangzhou Si Luoke Chemical Co., LtdThe hyper-dispersant of 7679 models.
As a preferred solution of the present invention, specifically, the Tea Saponin is the Tea Saponin that purity is not less than 98%.This
The selected Tea Saponin of invention is the product of Xi'an four seasons Biotechnology Co., Ltd.
The invention has the benefit that the formula of DOPO base expanding fire retardant provided by the invention is reasonable, main body fire retardant
For the graphene containing DOPO group, one side DOPO group has excellent flame retardant property, meanwhile, the addition of graphene is advantageous
In the mechanical strength improved and holding is formed a film；Starch phosphate melamine salt in formula is a kind of expansion type flame retardant, usually
It is prepared using starch, polyphosphoric acids, melamine, raw material sources are extensive, and cost is relatively low, and toxicity is smaller, and can and contain
Host system is collectively formed in the graphene of DOPO group, and forms between the graphene containing DOPO group a kind of fire-retardant
Synergistic effect；Tea Saponin in formula itself has a good expansion character, the introducing of Tea Saponin can also with contain DOPO base
Cooperative flame retardant and suppression cigarette effect are formed between the graphene of group, the nitrogen source for making up the graphene containing DOPO group insufficient is asked
Topic, and its source is wide, it is at low cost, and in the interface compatibility for improving fire retardant and epoxy resin, improve flame-retardant smoke inhibition side
Face has significant effect；It is compatible with system that the introducing of dispersing agent in formula efficiently solves the graphene containing DOPO group
The problem of property.
Below with reference to embodiment, the present invention is further described.
