Description

A kind of bolt lock solid glue

Technical field

The present invention relates to a kind of jelly, specifically a kind of bolt lock solid glue.

Background technique

After locking glue bolt both domestic and external and internal screw thread screw, generally locks rapidly in 10 seconds, can not be adjusted after locking, And many occasions, after needing bolt and internal screw thread to screw, adjusted in certain time, it cannot in rear certain time this requires screwing Locking, but cannot the time it is too long.The locking glue that we study thus, can guarantee 10 minutes or so and does not lock, and locking force Greatly, it is good to loosen performance, good seal performance.

Summary of the invention

The object of the present invention is to provide a kind of bolt lock solid glues to achieve the goals above, the technology that the present invention uses Scheme is as follows：

In order to solve the above technical problems, the technical scheme is that a kind of bolt lock solid glue, by the raw material of following weight proportion It is made：Methacrylate 60~70%, hydroxyethyl methacrylate 20~30%, modified white carbon black 2~5%, 1- methyl-1 phenyl Ethyl hydrogen peroxide 1~2%, N, N- diyl ortho-aminotoluene 0.1% flow auxiliary rheological agents 0.5%, ammonium salt dispersing agent 1.2%, anti-aging agent DDA, 4%, sodium gluconate 0.2%, sodium methyl silicate 0.2%.

The preparation method of the modified white carbon black is：

（1）First by gangue and flyash by weight 2：1 mixing, adds the stone of gangue, 0.1 times of flyash total weight parts English powder is sufficiently mixed, and granularity is crushed to after mixing less than 200 mesh, then grinding distribution 1~2 hour, then gangue, flyash, Quartz sand mixture and soda ash are by weight 1：60 are uniformly mixed, and melt 80 minutes through 1400~1500 DEG C of smeltings, then successively by 3~ Pure water extraction in 4 hours and 1~2 hour alcohol steep, then filter decontamination, and filtrate is finally concentrated and obtains to 45~46 Baume degrees Complex silicate sodium；

（2）Complex silicate sodium is first made into water glass solution, modulus is that 2.5~3.8, SiO2 content is 5~10%, then dense Degree is then to be warming up to 80 DEG C acidleach 15~20 hours in the sulfuric acid of 28~32 DEG C of 10~20% temperature, is stirred, adjust pH value be 5~ 7, it cures 20 minutes, using filter washing, drying, sorting, obtains modified white carbon black.

Locking agent of the invention locks the time 5 to 12 minutes in the environment of 25 DEG C of air humiditys 30%, the locking measured Power：

M12 bolt and GB6170 nut matching locking force >=60NM；

M16 bolt and GB6170 nut matching locking force >=120NM；

M20 bolt and GB6170 nut matching locking force >=170NM.

Specific embodiment

A kind of bolt lock solid glue, is prepared from the following raw materials in parts by weight：Methacrylate 68%, hydroxyethyl methacrylate Ethyl ester 22%, modified white carbon black 3%, 1- methyl-1 phenylethyl hydrogen peroxide 1.9%, N, N- diyl ortho-aminotoluene 0.1%, flowing stream Become auxiliary agent 0.5%, ammonium salt dispersing agent 1.2%, antioxidant D DA, 4%, sodium gluconate 0.2%, sodium methyl silicate 0.2%.

The preparation method of the modified white carbon black is：

（1）First by gangue and flyash by weight 2：1 mixing, adds the stone of gangue, 0.1 times of flyash total weight parts English powder is sufficiently mixed, and granularity is crushed to after mixing less than 200 mesh, then grinding distribution 1~2 hour, then gangue, flyash, Quartz sand mixture and soda ash are by weight 1：60 are uniformly mixed, and melt 80 minutes through 1400~1500 DEG C of smeltings, then successively by 3~ Pure water extraction in 4 hours and 1~2 hour alcohol steep, then filter decontamination, and filtrate is finally concentrated and obtains to 45~46 Baume degrees Complex silicate sodium；

（2）Complex silicate sodium is first made into water glass solution, modulus is that 2.5~3.8, SiO2 content is 5~10%, then dense Degree is then to be warming up to 80 DEG C acidleach 15~20 hours in the sulfuric acid of 28~32 DEG C of 10~20% temperature, is stirred, adjust pH value be 5~ 7, it cures 20 minutes, using filter washing, drying, sorting, obtains modified white carbon black.

The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any Those skilled in the art, made equivalent changes and modifications under the premise of not departing from design and the principle of the present invention, It should belong to the scope of protection of the invention.
