Description
Technical field
The invention belongs to adhesive techniques field, more particularly to a kind of super large emery wheel reinforcing glass fiber mat bonding
Agent.
Background technology
Emery wheel mesh sheet is the bone in resin wheel, and particularly important effect is played to the intensity of whole emery wheel, directly certainly
Determine the quality of emery wheel.Emery wheel mesh sheet be using emery wheel screen cloth be coated with bonding agent drying after punching form, it is necessary to when laminating non-woven fabrics,
Black paper and plastic sheeting, there is excellent tensile strength and flex stiffiness energy, be the optimal enhancing base materials of various resin wheels.And sand
Take turns the superior service life and tear resistance for directly affecting emery wheel of adhesive performance of mesh sheet.
Traditional emery wheel mesh sheet bonding agent is all manufacturer to be formed with reactor reaction, and storage time is short, bonding agent with
Methanol is solvent, and transport and storage all have very big potential safety hazard.And it can be caused in the building-up process of bonding agent a large amount of
Waste water, waste liquid, very big influence is caused to environment.And traditional caking agent formula is single, cause emery wheel backing wire piece and sand
The adhesion of son and resin is weak, with reference to not close, causes the not wear-resisting of emery wheel, service life is low.
On emery wheel mesh sheet bonding agent, have been reported in the prior art.As the B of patent CN 103481210 disclose one
Kind emery wheel mesh sheet bonding agent and preparation method thereof, the bonding agent is by thermoplastic phenolic resin 80-110 parts, curing agent 1-6
Part, thermosetting phenolic resin liquid 20-40 parts, alcohol 60-140 parts, toughener 0.5-2 parts, coupling agent 0.5-2 parts,
Plasticizer 0.5-2 parts form.Its preparation method is that alcohol is added in agitator, adds thermoplastic phenolic resin while stirring
Fat, 3-4 hours are stirred, treat that phenolic resin block all dissolves, add the thermosetting phenolic resin liquid containing coupling agent, plasticizer
And alcoholic toughener, stirring 3-4 hours add curing agent, continue to stir 4-6 hours, obtain the bonding agent；But should
The caking agent formula of emery wheel mesh sheet is very single, causes the adhesion of emery wheel backing wire piece and sand and resin weak, with reference to not close, leads
The not wear-resisting of emery wheel is caused, service life is low.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of stable performance and emery wheel mesh sheet intensity and bonding effect can be improved
The bonding agent of fruit, so as to improve the wearability of emery wheel and service life.
In order to solve the above technical problems, the technical scheme is that：A kind of super large emery wheel reinforcing glass fiber mat is used
Bonding agent, its innovative point are：The bonding agent is prepared from the following raw materials in parts by weight：2123 34~38 parts of phenolic resin,
0.05~0.15 part of 2127 34~38 parts of phenolic resin, 22~24 parts of ethanol, 0.5~1.5 part of methenamine and silane coupler；
Wherein, the silane coupler is from silane resin acceptor kh-550, silane coupler KH-560 and silane coupler DL-602
Mixture, and the mass ratio of silane resin acceptor kh-550, silane coupler KH-560 and silane coupler DL-602 be 2.4~
2.8:1.7~2.1:1.
Further, the silane coupler is even from silane resin acceptor kh-550, silane coupler KH-560 and silane
Join agent DL-602 mixture, and the matter of silane resin acceptor kh-550, silane coupler KH-560 and silane coupler DL-602
Amount is than being 2.6:1.9:1.
Further, the bonding agent is prepared from the following raw materials in parts by weight：2123 36 parts of phenolic resin, 2127 phenolic aldehyde
0.1 part of 36 parts of resin, 23 parts of ethanol, 1.0 parts of methenamine and silane coupler；Wherein, the silane coupler selects silane
Coupling agent KH-550, silane coupler KH-560 and silane coupler DL-602 mixture, and silane resin acceptor kh-550, silicon
Alkane coupling agent KH-560 and silane coupler DL-602 mass ratio are 2.6:1.9:1.
The advantage of the invention is that：Phenolic resin adhesion, heat resistance, Burning corrosion resistance, the anti-flammability that the present invention selects are excellent
It is different, and material is easy to get, it is cheap；Wherein 2123 phenolic resin have thermoplasticity in the presence of without curing agent, make it
Still there is the ability of reprocessing after impregnated glass fiber, 2127 phenolic resin also have curing characteristics again without curing agent,
Mesh sheet in emery wheel is combined with good cementability to abrasive material, and the dry and wet degree of mesh sheet can be adjusted in order to preferably adapt to gas
Influence of the time factor to mesh sheet；And the present invention uses ethanol not only to reduce the injury to human body as solvent, improve work
Condition, and similar compatibility principle is made full use of, reach the purpose that various components fully dissolve；
In addition, add a kind of silane resin acceptor kh-550, silane coupler KH-560 and silane coupler DL-602 in formula
Compound coupling agent is mixed, contains two kinds of different active genes in KH550 molecules --- amino and epoxide, for being coupled organic high score
Son and inorganic filler, strengthen its caking property, improve the performance such as mechanical, water-fast, anti-aging of product；Silane coupler KH560 is used
In glass fiber reinforced epoxy resin, ABS, phenolic resin, nylon, PBT etc., improve the bonding force of inorganic filler, ground and resin with
The performances such as the mechanical strength of its physical property, especially composite, water proofing property, electric property, heat resistance are improved, and wet
There is higher conservation rate under state；Silane coupler DL-602 is used for phenolic aldehyde, epoxy resin, can improve the intensity of composite；Cause
This, is 2.4~2.8 from mass ratio:1.7~2.1:1 silane resin acceptor kh-550, silane coupler KH-560 and silane is even
Join agent DL-602 mixture as excellent adhesive accelerant, phenolic resin adhesive in emery wheel manufacturing process can be improved
Cohesive, so as to improve the adhesion of emery wheel backing wire piece and sand and resin, and then improve the intensity of emery wheel mesh sheet；It is viscous using this
Emery wheel made of agent prescription is connect, its wearability is strong, so as to extend the service life of emery wheel.
