Description
Technical field
The present invention relates to field of material technology, and in particular to a kind of preparation method of nanostructured glue.
Background technology
Glue play the role of in terms of engineering-built it is important, be related to plank, fragment of brick, metal, cement, glass, stone,
The sticking problem of plastics, aluminum products etc., can all use glue.How much glue in the market can all have some defects, such as：
First, water-proof sealing is poor, and showing for adhesive interface leak just occurs in (such as bathroom) use time long in wet environment
As；2nd, it is chronically at wet environment and Signs of Mould occurs, such as under the more wet environment such as south or bathroom, kitchen, uses
Can be mouldy in the structure glue of the materials such as adhesion marble, glass, ceramics, or even come off；3rd, easily go out under dry climatic condition
Existing cracking phenomena；4th, with the increase of use time can gradually taper up, finally come off, and useful life be generally 10 years with
It is interior.
The content of the invention
Present invention solves the technical problem that being to overcome the defect of prior art being capable of waterproof sealing, mould proof, no there is provided one kind
Cracking, do not shrink, do not fall off, high-time a kind of nano-titanium magnesium structural silicone adhesive and preparation method thereof.
Technological means：The invention discloses a kind of preparation method of nano-titanium magnesium structural silicone adhesive, comprise the following steps：
The first step：By 107 glue, 45-48 parts of calcium carbonate, 8-10 parts No. 3 white oils, 3-5 that parts by weight are 36-38 parts
Stirring, dissolving in the silicone oil input high force dispersion machine of part, high force dispersion machine temperature control is at 60-120 DEG C, and rotating speed is 450r/
After min, stirring and dissolving 4-6h, melting extrusion in extruder is placed in；
Second step：Titanate coupling agent, the crosslinking of 0.2-0.5 parts of titanate esters first by parts by weight for 0.2-0.5 parts
Agent, 1-2 parts of nanometer titanium complex, 0.6-1 parts of pigment, 0.6-1 parts of nano-titanium micro mist, 0.6-1 parts of nanometer Mg micro mist
Put into high force dispersion machine, temperature control at 45-60 DEG C, rotating speed 300-600r/min, vacuum nitrogen gas is simultaneously forced into
2Pa, is reacted 2 hours, is subsequently cooled to 40 DEG C, and the raw material being stirred is placed in extruder and extruded；
3rd step：The material extruded in the first step and second step is blended to form highly viscous nano-titanium magnesium silicone structure
Glue.
High force dispersion machine temperature control is at 100 DEG C in the first step, and the stirring and dissolving time is 5h；Strongly divide in the second step
The temperature control of machine is dissipated at 50 DEG C, and rotating speed is 450r/min.
Wherein, the weight fraction of each material is preferably：
Or the parts by weight of each material are preferably：
Or the parts by weight of each material are preferably：
Beneficial effect：First, with higher sealing performance, can have during applied to positions such as bathroom, kitchen sinks
What is imitated prevents water from exosmosing；2nd, it is mould proof, mildew resistance is test by the modes of GB/T 1741 and meets testing standard；3rd, do not ftracture, do not receive
Contract, do not fall off, detected by a series of modes, test value substantially exceeds standard index, and actual use by user,
Do not occur any cracking, shrink the phenomenon such as come off；4th, this hair name structure glue is tested through anti-softening, and long shelf-life was up to 50 years, much
It is longer than other structures glue in the prior art.
