Abstract
The present invention relates to a technology for making high-density epoxy resin scrapers. Fiber layer cloth is heated, pressed and solidified by liquid resin glue. The liquid resin glue has the basic formula: 1 to 5 shares of MoS2, 70 to 95 shares of oxygen resin and 6 to 15 shares of dicyanodiamide solidifying agent. The technology of the present invention has the characteristic of reasonable technology. Made integral scrapers have the characteristics of long length, high strength, no deformation, fine and compact texture, abrasion resistance, accurate dimension, etc. The made integral scrapers can be made into long scrapers in 10 meters to more than tens of meters. The scrapers can be used for paper making industry, etc., and effectively ensure the high quality of products.
Description
The present invention relates to paper machine scraper plate technical field.
The prior art of the used scraper of papermaking equipment is: 1, metallic spatula: because metal is hard, in use seriously make drying cylinder and various papermaking rollers surface radially rill occur to paper machine dryer and the scuffing of various papermaking roller, shorten the service life of drying cylinder and various papermaking rollers, caused the paper quality of being produced poor.2, adhered overlength EPGCI plate scraper, though can not scratch drying cylinder and various papermaking roller, what adopt is adhered, every block of plate only has 2.5m long; Must be bonding when surpassing 2.5m.Abutting edge intensity is little, very easily fractures.3, cloth matter phenolic aldehyde scraper, this scraper adopts the cloth of coming off duty, cotton to do reinforcing material, phenolic resins is done matrix material, adopt the laminating technology compacting to form, though this scraper can not scratch drying cylinder and various papermaking roller yet, but its intensity is low, if guarantee its enough intensity, must adopt the way that strengthens thickness.So scraper is thickened, strengthened the contact area of scraper and drying cylinder and various papermaking rollers, thereby strengthened friction, waste power.And easy crimping, must take off every day from the paper machine, grinds, and the effort of taking a lot of work influences output.Simultaneously, length also is no more than 2.5m.
The purpose of this invention is to provide a kind of high density epoxy resin scraper manufacturing technique, its technology is reasonable, it is long that the monoblock type scraper made from this technology has length, the intensity height, indeformable, quality exquisiteness, closely knit, wear-resisting characteristics, be difficult for scratching drying cylinder and various papermaking roller, prolong its service life, can guarantee the high-quality of products such as papermaking effectively.
The present invention is achieved in that a kind of high density epoxy resin scraper manufacturing technique, it is characterized in that:
A, first obtaining liq resin glue, its composition weight umber ratio is:
MoS
21-5 part epoxy resin 70-95 part
Dicy-curing agent 6-15 part
B, with fibrage cloth impregnation, and heat press curing;
C, by dimensional requirement processing.
Heating press curing method can for: behind the impregnation, build up multilayer, be heated to 100-130 ℃, carry out the mould compacting, push and solidify at 90-130 ℃ after the demoulding.
Heating press curing method also can for: heating is pushed and is solidified for 150-220 ℃ in the time of the multi-layer fiber impregnation.
Fiber can be used high strength glass cloth, fibre glass chopped stand mat, carbon fiber and cotton etc.
The fiber impregnation resin content is good with 22-46%.
Liquid resin glue composition weight umber than in preferably adds silica flour 2-5 part, to improve its ABRASION RESISTANCE.
The advantage that the present invention has is: technology is reasonable, and it is long to have length with the monoblock type overlength scraper of manufacturing of the present invention, and the intensity height is indeformable, wear-resisting, and characteristics such as size is accurate can be made more than 10 meters the overlength scraper to tens meters.This scraper can be used for industries such as papermaking, can effectively guarantee the high-quality of product.
Be described further below in conjunction with embodiment, but not as a limitation of the invention.
Embodiment:
1, liquid resin glue set of dispense is such as following table:
Annotate: epoxy resin selects for use EP, UP or PF resin all can.
| Material | Embodiment (kg) | ||||
| 1 | 2 | 3 | 4 | 5 | |
| MoS 2 | 1 | 2 | 3 | 4 | 5 |
| Epoxy resin | 70 | 75 | 88 | 90 | 95 |
| Dicyandiamide | 6 | 8 | 11 | 13 | 15 |
| Silica flour | 2 | 5 | |||
2, technology one: make fibrage cloth (as high-density glass cloth, fibre glass chopped stand mat, carbon fiber and cotton etc.) by impregnation in the liquid resin glue, making its gel content is 22-46%, builds up multilayer, is heated to 100-130 ℃, suppress in tabular preheated mold, pressure is 4-8MPa/cm
2, carry out the demoulding; Be heated to 90-130 ℃ then and carry out post processing, it is fully solidified, the time is more than the 6H; Carry out machined by the size of scraper requirement at last, promptly make scraper.
3, technology two: multi-layer fiber layer cloth by in the liquid resin glue, is carried out continuous pultrusion by mould, and heating-up temperature is 150-220 ℃; Time fully solidifies it greater than 6H; Last machined is shaped and obtains scraper.
The overlength scraper sheet material made from above-mentioned technology has intensity height, indeformable, wear-resisting characteristics, long service life, and size is accurate.Every large-scale paper machine, can increase income and economize on spending about 1,600,000 yuan every year.
