Description
Technical field
The present invention relates to the high heat-resisting BMC composites of one kind.
Background technology
BMC (Bulk Molding Compounds) is with special unsaturated polyester thermosetting hardening resin, with excellent
Electrical insulative property, heat resistance, flame resistance, high mechanical properties dimensional stability, corrosion resistance, water resistance, shrink stability etc.,
Highest product in various thermosetting hardening moulding materials.
BMC ejection formations are also known as BMC injection molding.Britain is referred to as DMC（Expect BMC）Ejection formation.
The stock of this ejection formation is unsaturated polyester, styrene resin, along with mineral filler, colouring agent and 10-30%
（Percentage by weight）The composition such as fiber glass reinforcement block plastics.Length of Glass Fiber typically takes 6-12mm, and long is reachable
25mm, BMC and SMC are named as to this new moulding material using unsaturated polyester as the glass fiber reinforcement of binding agent（Piece
Shape moulding compound）；These block stocks are category reinforced thermosetting plastics.Its product gone very high resistance, moisture-proof, have excellent machine
Tool performance and less shrinkage factor, therefore can be used to produce the product in thick section, it is widely used in electronics industry and household electrical appliance
Aspect, makees various housings and finding etc..
But performance of the material in terms of high temperature resistant and anti-shrink also needs to further optimization, makes it in radio, essence
It can just be more suitable for when being used in the equipment instrument such as close instrument.
The content of the invention
It is contemplated that overcoming the deficiencies in the prior art, there is provided the high heat-resisting BMC composites of one kind, the BMC composites
Heat-resisting, water-fast, oil resistant, excellent corrosion resistance adapt to various moulding process, can meet the performance requirement of various products.
A kind of high heat-resisting BMC composites that the present invention is provided, the composite uses short glass fiber and carbon fiber
The material shape moulding material that powder vinylite is composited.
The short glass fiber uses dilute HCl and Silane coupling reagent KH-570 working process mistake successively.
The working process process to short glass fiber is specially：
The short glass fiber is placed in 2 h, dry for standby in 105 ± 2 DEG C of drying boxes；
E- glass fibres are soaked in concentration for the dilute HCl solution of 0. 5,1. 0,1. 5,2. 0 and 2. 5 mol/L respectively
In 1 h, then dry up；Weigh respectively and account for glass fiber quality fraction 0. 3%, 0. 6%, 0. 9%, 1. 0%, 1. 1% after processing
And 1. 2% Silane coupling reagent KH-570, be each configured to again 4% the aqueous solution；
Glass fibre is infiltrated in solution and stands 2 h, Silane coupling reagent KH-570 is coated glass fibre；Then after handling
E- glass fibres be put into 130 ± 2 DEG C of baking ovens constant temperature and handle 4 h, 1 h is cooled down after taking-up at room temperature, is cut to 9 mm's
Short fine and sealing preserve, is made with HCl and Silane coupling reagent KH-570 composite modified short glass fiber.
It is fine that the composite includes carbon fiber powder vinylite, diallyl phthalate, the third fat, staple glass
Dimension, zinc stearate, talcum powder, zinc oxide and diphenyl peroxide first.
Its quality proportioning is：32-35% carbon fiber powder vinylite, diallyl phthalate is polyester resin
20%-40%, 1%-3% the third fat, 22-25% short glass fiber, 1%-3% zinc stearate, talcum powder is polyester resin
2%, remaining zinc oxide and diphenyl peroxide first for being 0.01%.
The quality proportion of third fat is 2%.
The quality proportion of the zinc stearate is 2%.
The present invention uses above technical scheme compared with prior art, with following technique effect：
1. high-fire resistance：I reaches 170 DEG C of more than, thermal deformation by the BMC composite new product Long-term service temperatures of company's research and development
Temperature reaches 300 DEG C
2. zero shrinks：Solved to be molded after-contraction with addition shrinking agent and ultra-fine filling material during preparing molded composite material
The problem of deformation, because matrix is the relatively low vinylite of shrinkage factor, the selection preferable styrene solution of lower shrinkage is as low
Contracting agent, the characteristics of composite after the mutual preparation of different meshes filler then can reach zero contraction.
3. low-gravity：Because carbon fiber proportion is relatively low, adjustment formula changes the ratio of carbon fiber and filler, and preparation is answered
Condensation material.
The compatibility of glass fibre and resin is improved, the adhesion between E- glass fibres and organic resin is improved,
So as to improve the anti-bending strength of BMC products；When Silane coupling reagent KH-570 mass fraction increases to 1. 2% from 1. 0%,
R-Si of fiberglass surfacing-O-group has tended to saturation, therefore the bending strength on BMC samples influences very little.
