Description
Technical field
The present invention relates to the production technologies of organosilicon sealant, belong to technical field of polymer materials.
Background technique
The production of organosilicon sealant is 107 silicon rubber and fume colloidal silica, nano-calcium carbonate with make versus buy
Calcium, extraordinary organoalkoxysilane, silane adhesion promoters, plasticizer, pigment and catalyst etc. are raw material, pass through mixing facilities physics
Mixing homogenizes obtained.After raw material, process flow determine, the mixing of material is homogenized, especially plasticizer, pigment and catalysis
The dosages such as agent are less, but act on the uniformity that huge material (being referred to as small powder) is dispersed in finished product, are to ensure that cooperation material
Quality and the important link for improving material effect, are the most important guarantees of organosilicon sealant quality stability.
The mixing of material is exactly that under the effect of external force, various material components blend mutually, various in any volume
The particle of component is uniformly distributed.
There are many ways to mixing, such as mechanical mixing, pneumatic type mixing, impulse mixing, wherein mechanical mixing
It is relatively conventional.For being mechanically stirred, mixed process can be divided into 3 stages: first with the movement of bulk material fritter
Based on the convection current mixing of formation, mixture homogeneity is improved rapidly；Secondly, mutual sliding that particle is asked and impact or blade and wall
The shear action of compression and extension between face, mixing velocity are steady；Third, particle position exchange diffusion with separate work
With equilibrium state is reached, i.e. mixing uniformity keeps stablizing or slightly fluctuating.
Mixing is generally divided into batch mixed and continuous mixing.Batch mixed is the ratio by various material components according to formula
A certain number of batches are made into, the mixing machine that this batch is sent into interval work is mixed in batches.Mixing one
A period produces a batch.This mixing can promptly change the ratio and kind of ingredient, change batch comparison side
Just, between every batch of mutually mix it is less, but operate it is more frequent.Continuous mixing is continuously to count various material components respectively
Amount, is continually fed into continuous mixer or corresponding mixing apparatus is mixed.This technique is adapted to more fixedly produce
The material of a certain kind and formula, change it is batch cumbersome, and since residual material is more, cause between two batches mutually mix it is heavier.
Organosilicon sealant generallys use (high speed) dispersion machine (also referred to as blender) batch mixed, mixed including small powder etc.
It closes.But between batch and in the conversion production of different size glue kind, dispersion machine need to be cleared up and be cleaned, there are sizing material losses greatly,
The disadvantages of wasting more consumptive material, large labor intensity, lower production efficiency.Meanwhile in sizing material transfer, contact of the sizing material with air can
The quality of product can be will affect.Introduced in the mixing of silicone sealant collagen-based materials it is a kind of it is efficient, closed, can quantity-produced it is mixed
Equipment is closed, it is imperative.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of production technology of organosilicon sealant, include the following steps:
A kind of production technology of organosilicon sealant, includes the following steps:
(1) base rubber, filler and plasticizer are added in dispersing agent, temperature is 70-80 DEG C, vacuum degree is higher than -0.092MPa's
Under the conditions of stir 1~3h, cooling obtain high mixing；
(2) high mixing enters storage tank after condensation is cooled to lower than 50 DEG C, and base-material, which measures, in storage tank enters static mixer, then with
Curing agent, silane coupling agent and the mill base of metering enter terminal automatic packer after mixing, which carries out packing, becomes finished product glue.
In above-mentioned raw materials by weight, 100 parts of base rubber, 30-40 parts of filler, 5-10 parts of plasticizer, 5-10 parts of curing agent,

The dilute base tributanoximo silane of base silane, second, four butanone oximino silanes, any one and silicon in methyl tributanoximo silane
The colloidal sol mixture of 10:0.5-1 in mass ratio.Plasticizer selects inert polysiloxane, is commonly called as silicone oil, is mainly used to improve sealing
It is glue elasticity, consistency, extrudability.Silicone oil and base rubber are all siloxanes, have good compatibility, energy longer-term persistence is in sealant
It is interior, improve intensity.
The plasticizer is two butanone oximino silane of dimethyl and the silica solution mixture of 10:0.6 in mass ratio.
The plasticizer further includes Dimethyldichlorosilane hydrolysate or Dimethyldichlorosilane hydrolysate and silica solution
The mixture of mass ratio 10:0.5-1, the wherein octamethylcy-clotetrasiloxane in Dimethyldichlorosilane hydrolysate and decamethyl ring
The total content of five siloxanes reaches 65% or more.
The curing agent includes diethylenetriamine or triethylene tetramine, isopropanolamine.
The silane coupling agent is KH540, KH550, KH570, KH900.Above-mentioned silane coupling agent can also be two
Dimethyl dichlorosilane (DMCS) hydrolysate, wherein octamethylcy-clotetrasiloxane and five silicon oxygen of decamethyl ring in Dimethyldichlorosilane hydrolysate
The total content of alkane reaches 65%-68%.Coupling agent is also multi-functional silane compound, its main function is to improve sealant
Adhesion strength and bonding range.Silicone sealant can cling the contribution that various construction materials are mainly it.
The mill base is pigment, alkyl polyoxyethylene ether, styrene maleic anhydride copolymer solution through mass ratio 1:
The mixture of 0.9-1.2:0.5-0.6.
Technical solution of the present invention is mixed using static mixer, and mixed process is by series installation in hollow pipe
What the mixed cell of the different size in road carried out.It is when making fluid and left-handed due to the effect of mixed cell, when and rotation of turning right,
Constantly change flowing mixing machine direction, not only pushes core flow to periphery, but also push peripheral fluid to center, to cause
Good radial direction mixed effect.At the same time, the turning effort of fluid itself can also be sent out on the interface of adjacent component junction
Raw, this perfect radial circular flow immixture makes material obtain uniformly mixed purpose.
Static mixer impact flow various types panel element in pipeline by fluid increases the speed of laminar flow of fluid movement
Gradient forms turbulent flow.It is " segmentation-position is mobile-converges again " when laminar flow；When turbulent flow, fluid in addition to above-mentioned three kinds of situations,
Violent vortex can be also generated in section direction, had very strong shearing force in fluid, so that fluid is further divided mixing, most
It is mixed to form required emulsion eventually.
