By part of it be ground into granular size be 100 ~ 200nm particle A it is spare, another part be ground into granular size be 10 ~
The particle B of 40nm is spare；
B. by operate a obtained by particle A and particle B according to weight ratio 1：0.4 ~ 0.6 is mixed, and is then put into and is changed jointly
Property liquid in, heating keep modification liquid temperature be 45 ~ 50 DEG C, be carried out at the same time supersound process, be filtered after 1.5 ~ 2h, it is finally right
Filtrate be dried processing after functional stuffing it is spare；Each ingredient and its corresponding weight percent are in the modification liquid：
Silane coupling agent 8 ~ 10%, sodium pyrophosphate 0.5 ~ 1.5%, ethyl alcohol 3 ~ 5%, rosin resin 2 ~ 4%, surplus are water；Two kinds of particles are put
Enter in modification liquid, carries out surface coupling modifier processing using silane coupling agent, further promote the compatible of the ingredients such as itself and lotion
Property, while under the continuous peptizaiton of ultrasound, small particle silicas is gradually deposited on large granular silicon dioxide, while profit
Bonding is carried out to its surface with rosin resin to wrap, form a kind of compound filler particles, be conducive to the heatproof for promoting adhesive
Performance；
（2）It is prepared by adhesive：
A. it is spare to weigh following substance by corresponding parts by weight：80 ~ 85 parts of 2-EHA, methyl methacrylate
15 ~ 20 parts, 2 ~ 4 parts of methacrylic acid, 0.1 ~ 0.15 part of initiator, 1 ~ 3 part of emulsifier, 3 ~ 6 parts of acrylamide, acrylic acid hydroxyl second
2 ~ 5 parts of ester, step（1）20 ~ 25 parts of functional stuffing obtained, 10 ~ 15 parts of toluene；
B. by operate a obtained by each substance jointly mixing be put into reaction kettle, heating keep reaction kettle in temperature be 78 ~
It 82 DEG C, is taken out after being stirred continuously 40 ~ 50min of reaction, it is spare that adhesive is obtained after natural cooling；
（3）It is prepared by double faced adhesive tape：
A. with bar by step（2）The surface that adhesive obtained is spread evenly across base material forms straight rubberised layer, then
Adhesive is applied to be posted again in release paper or release film and forms that be posted glue-line spare on another surface of base material；
B. it operates under conditions of the base material for being equipped with straight rubberised layer and being posted glue-line obtained by a is respectively placed in 85 ~ 95 DEG C and toasts 3
Double faced adhesive tape is got product after ~ 5min.
Further, step（1）Operate the cleaning treatment described in a to be the hydrochloric acid solution for being first 8 ~ 10% with mass fraction
Soaking and washing processing is carried out, takes out after 15 ~ 20min and is rinsed one time with deionized water again.
Further, step（1）Calcination processing described in operation a be cleaned silica is put into 700 ~
50 ~ 60min of calcination processing under conditions of 730 DEG C.
Further, step（1）The frequency of sound wave for operating the supersound process described in b is 70 ~ 75kHz.

Inorganic nano-particle has small-size effect, surface-interface effect, can be larger the interface generation between other components
Active force, cohesion, cohesive force etc. to enhance adhesive reduce painting so as to improve the usage amount of adhesive
The thickness of layer, but find that the thickness used due to adhesive is smaller in actual use, under higher temperature in use environment, mistake
Adhesive coating can be divided into big and small not equal region by the inorganic filler of degree dispersion, whole cohere spy to reduce
Property, has carried out improvement processing to this present invention, functional stuffing has been made using silica as raw material first, wherein being crushed point
Grade is at the particle of two kinds of variable grain sizes, and finally modified a kind of large granular silicon dioxide is made is core, small particle silicas
For the bulk structure of surrounding layer, this structure macroscopic view area is larger, improves the contact area with remaining ingredient, while with little particle
The projection portion that silica is formed can promote the crosslinking complexity with lotion matrix, while its is compound as a kind of whole knot
Structure is filled, and can weaken the dividing degree to relatively thin adhesive coating, be conducive to enhance its at relatively high temperatures cohere spy
Property, it is finally used cooperatively jointly with remaining ingredient, performance is greatly improved.
The present invention has the following advantages compared with prior art：
The present invention has carried out special improvement to the processing preparation process of double faced adhesive tape and has handled, and effectively enhances it in high temperature
Under cohere stability, be conducive to promoted corresponding product quality stability, application and popularizations value it is higher.
