Abstract
The invention discloses an ultraviolet-resistant organosilicon adhesive which comprises an original silicon adhesive layer and a functional layer. The functional layer comprises the following components in parts by weight: 50-70 parts of organosilicon adhesive, 30-50 parts of hydroxy polysiloxane, 3-5 parts of dibutyltin diacetate, 1.2-2 parts of composite stabilizer, 1-2 parts of lubricant, 5-30 parts of reinforcer, 0.02-0.05 part of pigment, 5-8 parts of toughener and 30-40 parts of ultraviolet absorbent. The ultraviolet absorbent is a chlorobenzotriazole ultraviolet absorbent. By improving the formula, the ultraviolet absorbent and organosilicon adhesive functional layer master batch are mixed and molten by heating, and drawn to form the organosilicon adhesive, thereby solving the problem that color in the organosilicon adhesive in the prior art influences the visual effect. Meanwhile, by the aid of the weather resistance of the organosilicon adhesive, the ultraviolet absorbent can not easily migrate, thereby greatly prolonging the timeliness of the ultraviolet-resistant function.
Description
Technical field
The present invention relates to a kind of uvioresistant organic silica gel.
Background technology
The sizing of organic silicon adhesive is by the siloxanes of one or more line styles, ring-type or branched chain type, under catalyst action, and the line style of the high molecule mass obtained by reactions such as balance, addition or condensations or cross-linking type siloxanes composition.Organic silicon adhesive mainly contains rubber-type and resin type two class.Organic silicon adhesive has the features such as high temperature resistant, clinging power stable, persistence is good, is widely used in the every field such as aviation, navigation, spaceship, rocket-powered missile, nuclear power, electronic apparatus industry.
Along with the progressively expansion of the range of application of organic silicon adhesive system adhesive tape, all trades and professions propose new requirement to the quality of organic silicon adhesive system adhesive tape and the application of properties.The adhesive surface of many irregular and different treatment technique, makes the application of organic silicon adhesive system adhesive tape be changed to special use by simple.The preparation technology of general organic silicon adhesive system adhesive tape is surface organic silicon adhesive being coated on adhesive band base (as various thin, paper etc.).One large purposes of organic silicon adhesive system adhesive tape makes protection, for the protection of the surface of the material such as glass, sheet metal, plastic plate of transport or use procedure, its surface scratched from contact stain(ing) or polishing scratch.
Existing organic silica gel is easy to be subject to ultraviolet destruction, needs to use the packaging protecting material with anti-ultraviolet function.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of uvioresistant organic silica gel.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of uvioresistant organic silica gel of the present invention, comprises original layer of silica gel and functional layer, described functional layer its count by weight, comprise following composition:
Organic silicon adhesive 50-70;
