Abstract
The invention discloses vitrified powder and relates to filler of silica gel and other chemical raw materials. The vitrified powder is prepared from, by weight, 10-40 parts of white mica, 10-30 parts of wollastonite, 10-40 parts of quartz powder, 10-30 parts of zinc borate, 10-20 parts of nanometer magnesium hydroxide, 3-15 parts of aluminum oxide and 3-10 parts of titanium dioxide, and the materials need to be treated by a silane coupling agent. The vitrified powder is easy to process, low in production cost and capable of being ablated into a ceramic shell when added into rubber or polyolefin, and a burnt object is protected against damage. Compared with traditional vitrified powder, the sintering temperature of a flame resistance ceramic polymer can be decreased, the influence on the mechanical performance of the polymer is small, the preparation reaction speed can be improved, production efficiency is improved, and the production cost is reduced.
Description
Technical field
The present invention relates to the filler of a kind of silica gel or other industrial chemicals, particularly relate to a kind of Vitrified powder.
Background technology
Ceramics is protected as one self-control formula all the time, and Vitrified powder is typically added to silicone rubber or polyene
Hydrocarbon tire out polymer adds in rubber or polyolefin can the housing of ablated one-tenth ceramic-like, the object that protection is burnt is without damage,
The sintering temperature enabling to fire resistant ceramic fluidized polymer relative to traditional Vitrified powder reduces, the mechanical performance shadow to polymer
Ring little, and preparation response speed can be improved, improve production efficiency, reduce production cost.
Summary of the invention
It is an object of the invention to provide a kind of Vitrified powder, this Vitrified powder is possible not only to after low temperature becomes porcelain and becomes porcelain hard
Firmly, the filler simultaneously added does not interferes with other mechanical performances of silicone rubber yet.Self-control boric acid zinc-type Vitrified powder is utilized to drop
Low one-tenth porcelain temperature, is substantially improved into the hardness after porcelain and smoothness, and cubical contraction is minimum.
It is an object of the invention to be achieved through the following technical solutions:
Advantages of the present invention with effect is:
Vitrified powder of the present invention, improves original technology and filler, and it not only has the highest fire resistance, is adding simultaneously
Do not interfere with other machinery and the mechanical properties adding post-consumer polymer after filled, utilize self-control boric acid zinc-type Vitrified powder permissible yet
Reducing into porcelain temperature, hardness porcelain after and smoothness are substantially improved into, cubical contraction is minimum, can be satisfied with defeated high tension cable,
Building doors and windows rubber seal strip, rubber vehicle parts and the features such as field reliably use such as electric.
