The method that an original silicone sealant adopts common dimethicone is changed to the method which adopts quaternary ammonium salt end group modified dimethyl polysiloxane so that the silicone sealant for the fish tank can keep colored for a long time, moreover, mildewing and bacteria breeding are not prone to occurring, the sealant is environmentally friendly, and the fish tank can keep clean and attractive for a long time.
Description
Technical field
The present invention relates to a kind of fish jar fungi-proofing anti-yellowing variable color silicone sealant of one pack system and preparation method thereof, belongs to close
Sealing technical field.
Background technology
Fish jar is the glass wares for raising tropical fish or goldfish, plays a part of to view and admire, both built to fish
One warm family, also ensure that the safety of overall living environment.Fish jar is even more must not in being related to when household geomantic omen etc. is decorated
The goods of furniture for display rather than for use that can lack, is the perfect adaptation with space, is household, handles official business, the soul honorific Buddhist monk of commercial space.And the sealing of fish bowl system
Property and structural stability with adopt fluid sealant species and performance it is relevant.The more fish jar glue of domestic application is silicone at present
Glue, mainly due to the excellent ageing-resistant performance of silicone adhesive, sealing, compatibility and with good viscous between glass and base material
Connect performance.Fish jar glue is the important component part of fish jar, directly determines the quality of fish jar quality.But fish jar is used as decoration
Product, not only require his practicality, and aesthetic property are also particularly important, so part of the fish jar glue as fish jar, its color is straight
Connect the beauty function that have impact on fish jar.
Domestic manufacturer generally using transparent fish jar glue come bonding fish jar, using this transparent product processes letter
Single, product cost is low, adjusts colloidal property more convenient.But, only high-end product cannot be met in this transparent product
The rigors that product and some special dimensions are proposed to fish jar glue, particularly require that fish jar glue has and suppress xanthochromia, mould proof kill
Bacterium, bright color, rapid curing, the adhesive property of lasting high intensity and high-peeling strength.
Chinese patent document CN101724268A (application number：200910194242.8) a kind of producer of silicone adhesive is disclosed
Material is added mixing in double screw extruder, stirring to be obtained by method, and the material includes:Polysiloxanes, crosslinking agent, filler, increasing
Modeling agent, coupling agent, catalyst.
Chinese patent document CN 105368378A (application numbers：201510968119.2) disclose covering with paint property silicone adhesive and
Its preparation method；The paintability silicone adhesive, raw material are constituted in parts by weight, including：α, alpha, omega-dihydroxy polydimethyl silica

On the one hand above-mentioned silicone adhesive does not add pigment, for the mechanical strength and viscosity of silicone adhesive after addition pigment
Can decrease, and due to Long Term Contact water, easily in the surface mould growth of glue, affect attractive in appearance and cleaning, especially exist
It is on water and air interface, particularly evident, therefore, find suitable component and constitute under the requirement for ensureing silicone adhesive color, machinery
Intensity and adhesive property do not make a difference, and are difficult breed bacteria, mouldy, color can be kept for a long time not change, and become high-end at present
Problem demanding prompt solution in fish jar glue development process.On the other hand, current silicone sealant does not all have very in terms of feature
Good progress, particularly fish jar silicone adhesive.As fish jar is contacted with water for a long time with silicone adhesive, result in a humidity environment
Mouldy, breed bacteria is particularly easy to, that is, is affected attractive in appearance, is not easily cleaned again, and deteriorating water quality can be caused, therefore develop these pins
It is very necessary to the special glue of specific environment.
In products innovation, in the case that high-quality is required, continue, using original transparent silicone colloid system, can not expire
The requirement of sufficient some high targets, therefore the urgently exploitation of high-end fish jar glue, realize the innovation of product and significantly rising to for performance.
