Description
Technical field
The present invention relates to a kind of phenolic resin black functional master batch and preparation method thereof, and in particular to one kind is with nano material
Modified colour carbon black is phenolic resin black functional master batch of coloring agent and preparation method thereof.
Background technology
It using phenol and formaldehyde is raw material in acidic catalyst that phenolic resin, which is,（Or base catalyst）Under the conditions of, it is polymerized
High polymer material.Its stable processing technique is simple to operate, and the prices of raw materials are cheap, and has good heat resistance, and electricity is absolutely
Many advantages, such as edge, corrosion resistance, low smokiness, product size stability.Therefore, using phenolic resin as main raw material(s)
Phenolaldehyde moulding compound（It is commonly called as phenolic moulding powder）Have extensively in many fields such as household electrical appliance, domestic cookers, Aero-Space, auto industry
Application.In numerous phenolic molding compound material products, black product is occupied an leading position, and constitutes about more than the 95% of product population.Mesh
Preceding phenolaldehyde moulding compound is mainly dyed with oil black nigrosine and carbon black.
Oil black nigrosine is earliest organic synthetic dye.It has strong coloring force, and good fluidity, photo absorption performance is strong, face
The advantages that color stability is good.It is easily scattered in phenolaldehyde moulding compound, dyeing capacity is strong, and the product of production is black and bright.But oil is molten
For nigrosine in production, environmental pollution is than more serious；Because containing chromium to also having certain influence in Human Physiology health.With
China《Law on Environmental Protection》Strict implementation, the production cost more and more higher of oil black nigrosine, the growth of selling price also at double.
In black phenolaldehyde moulding compound, color matching cost has accounted for selling price 7%~9%.The economic effect of enterprise is had a strong impact on
Benefit.Carbon black is also one of ancient black dye and relatively inexpensive.But carbon black should not disperse, influence to dye.Present work
The carbon black particle almost spherical of industry production, particle diameter is between micron and nanometer.Many particles are often agglomerated into three-dimensional key branch
Chain or aggregating state.The dyeing capacity of carbon black has necessary correlative connection with self structure, in general the high carbon black of structure
It is easier to disperse, but dyeing capacity is relatively low, the low carbon black dyeing power of structure is higher, but needs bigger cut when scattered
Shear force.Colour carbon black is that scattered one kind is most difficult in all pigment.In order to reduce production cost, the performance of enterprises, phenolic aldehyde mould are improved
Plastics-production enterprise largely substitutes oil black nigrosine using carbon black.
At present, the main technique of phenolaldehyde moulding compound application carbon black dyeing is carbon black（Or add a small amount of glossy black）With phenolic aldehyde tree
After the blending of the other materials such as fat, wood powder, methenamine, inorganic filler, plastified in two-roll mill and dyeing is handled, so
Cooling crush is granulated afterwards.This traditional handicraft has certain effect to the dyeing cost for reducing phenolaldehyde moulding compound；But to carbon black
Disperse and utilize have certain limitation.Major defect is as follows：（1）Dosage is bigger；（2）It is scattered uneven；（3）Products appearance
Unsightly；（4）Product is more crisp；（5）Influence the curing rate of phenolic resin；（6）Easily pollution production link.
Through market survey, currently also the molten aniline of oil is substituted using colour carbon black without a kind of in phenolaldehyde moulding compound production
Black, carbon black and the product for obtaining more satisfactory effect.Therefore, in order to reduce the dyeing cost of phenolaldehyde moulding compound, phenolic aldehyde is improved
The combination property of resin, it is necessary to research and develop a kind of Color is good, production cost is low, stable performance, good fluidity, using simplicity
Multi-functional resins masterbatch.
