(1) preparation of scraper base material: base material is selected resin glue for use, and the composition weight umber of this resin glue is such as following:
38-50 parts of novolac epoxy resins,
1-3 parts of epoxy resin tougheners,
5-12 parts of dicyandiamides,
0.003-0.008 part of imidazoles,
13-15 parts of dimethyl formamides,
10-20 parts in acetone,
Silicon powder 15--20 part,
1.5 parts of molybdenum bisuphide;
(2) with multi-layer fiber cloth, through the high temperature gluing of 160 degree, cure under pressure again heats up.
In the said method step (1), described novolac epoxy resin is that described cloth is carbon cloth, glass fabric or cotton in F51 or NPPN638S or the KEP-1138 said method step (2);
In the said method step (2), described intensification cure under pressure, the temperature of its intensification is 240-260 degree,
The pressure of pressurization is 50-80 kilograms every square centimeter and solidifies.
Two, the shape of scraper is constructed as follows:
The novolac epoxy scraper that adopts above-mentioned base material to make, its version is as follows:
The length of this scraper customizes on demand, and the thickness of scraper is 1.5-5mm; The width of scraper is 76-200mm; This scraper side along its length puts the first edge on a knife or a pair of scissors, and blade angle is 20-60 degree angles; This scraper is a link in a side of not putting the first edge on a knife or a pair of scissors, in order to connect knife rest.This link can be that the riveting copper rivet is connected with the connected mode of knife rest, or the connection of riveting copper butterfly sheet, or opens the U-lag connection at link.
When described usefulness riveting copper rivet connected, its copper rivet spacing was 300-550mm, and copper rivet length is 5-10mm;
When described usefulness riveting copper butterfly sheet connected, its copper butterfly sheet spacing was 300-550mm, and copper butterfly sheet thickness is 0.15-0.45mm;
Described its U-lag spacing is 100-150mm when link is opened the U-lag connection, and the U-lag degree of depth is 30-35mm, and the U-lag width is 100-150mm.
The utility model novolac epoxy scraper has the following advantages:
1. high temperature resistant, can reach 350 and spend not deliquescing, indeformable.
Scraper can 200 meters in non junction.
3. linearity is strong, and 200 meters long errors are no more than 3.5mm.
4. disgrace good toughness, embrittlement not, the edge of a knife place of putting the first edge on a knife or a pair of scissors zigzag can not occur.
5. be of close texture, the intensity height, a side of not putting the first edge on a knife or a pair of scissors can riveting copper rivet, riveting copper butterfly sheet or open U-lag and connect, it is more firm that it is installed in knife rest, difficult drop-off.It is useful for the knife rest of all size, various models.
