Abstract
The invention discloses a dipping adhesive for flexible industrial canvas and a preparation method of the dipping adhesive. The dipping adhesive comprises raw materials in parts by weight as follows: 20-30 parts of distilled water, 0.035-0.045 parts of sodium hydroxide, 55-65 parts of butadiene-vinyl pyridine latex, 20-30 parts of natural latex, 6-7 parts of ammonium water and 75-85 parts of a phenolic resin solution, wherein the phenolic resin solution comprises raw materials in parts by weight as follows: 150-170 parts of distilled water, 0.15-0.25 parts of sodium hydroxide, 10-11 parts of resorcinol and 12-14 parts of formaldehyde. Compared with the prior art, the dipping adhesive adopts phenolic resin prepared from resorcinol and the formaldehyde solution as well as butadiene-vinyl pyridine latex and natural latex as main raw materials, so that the canvas has better flexibility, the adhesion performance between a framework layer and a rubber layer is improved, the service life of a conveyor belt is prolonged, and the conveying accuracy of the conveyor belt is improved.
Description
Technical field
The invention belongs to canvas process field, be specifically related to dipping solution of a kind of flexible industrial canvas and preparation method thereof.
Background technology
The framework material of conveying belt is polyester dipped canvas, polyester material has outstanding over-all properties, as high in breaking tenacity and Young's modulus is high, rebound resilience is moderate, therefore polyester dipped canvas is as the main framework material of conveying belt goods, instead of traditional fabric conveying belt field at home and abroad and has been able to widespread use.
Polyester dipped canvas is the important component part of conveying belt, what current polyester canvas impregnation adopted in producing usually is two bath methods, first bath carries out pre-treatment (usually with epoxy or isocyanate ester compound), and the second bath is then traditional Resorcinol-formaldehyde-latex dipping liquid.By the canvas of this kind of dipping process in life-time service, owing to lacking certain snappiness, can depart from glue-line at flexing place, thus can not well fit together, make conveying belt easily frayed, skid, affect transmission effect.Therefore, improve the flexibility of dipped canvas, extending the work-ing life of conveying belt, is a current problem urgently to be resolved hurrily.
Improving existing gum dipping process is the important means improving canvas snappiness and conveying belt ply adhesion effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of dipping solution of flexible industrial canvas, by controlling proportioning raw materials, improve the snappiness of dipped canvas, enhance the bonding effect between itself and glue-line, extend the work-ing life of conveying belt, improve the accuracy that conveying belt transmits.
Present invention also offers a kind of preparation method of dipping solution of flexible industrial canvas, make the canvas obtained have good snappiness, enhance the bond properties between casing ply and rubber layer.
The dipping solution of a kind of flexible industrial canvas provided by the invention, comprises the raw material of following weight part:
Described liquid phenolic resin, comprises the raw material of following weight part:
Wherein, Resorcinol and formaldehyde monomers mol ratio are 1:1.7.
Chun Du≤96% of described sodium hydroxide, the mass percentage concentration of formaldehyde solution is 37%, and the solid content of vinyl-pyridine latex is 39wt% ~ 42wt%, and the solid content of natural rubber latex is 30wt% ~ 40wt%, and the mass percentage concentration of ammoniacal liquor is 18% ~ 20%.
The preparation method of the dipping solution of a kind of flexible industrial canvas provided by the invention, comprises the following steps:
(1), according to formula, by distilled water and sodium hydroxide mixing, stir until dissolve;
(2) add the vinyl-pyridine latex of formula ratio, stir;
(3) add the ammoniacal liquor of formula ratio, stir;
(4) add the liquid phenolic resin of formula ratio, stir 30-40 minute, the dipping solution of obtained flexible industrial canvas.
The preparation method of described liquid phenolic resin, comprises the following steps:
A, according to formula ratio, by distilled water and sodium hydroxide mixing, stir until dissolve;
B, add the Resorcinol of formula ratio, stir until dissolve;
C, add the formaldehyde solution of formula ratio, continuously stirring, obtained liquid phenolic resin.
Continuously stirring described in step c, temperature controls at 30 DEG C, and the time is 3-4 hour.
In the present invention, owing to having introduced pyridine groups in vinyl-pyridine latex, polarity nitrogen-atoms on pyridine ring can react with the organic group on liquid phenolic resin and fiber, form hydrogen bond and dipole to combine, natural rubber latex have snappiness, bonding time film forming properties good, glued membrane be imbued with snappiness, excellent flexible resistance; Vinyl-pyridine latex, natural rubber latex and canvas is made to have good bond properties.The present invention reaches goal of the invention by optimizing resorcin/formaldehyde monomer ratio, especially when in the present invention, liquid phenolic resin resorcin/formaldehyde monomer ratio is 1:1.7, the bridging property feature of existing heat-reactive phenolic resin, also have the flexible characteristic of certain novolac resin, therefore the canvas obtained also have certain thermotolerance and meltbility.
Compared with current technology, dipping solution provided by the invention adopts Resorcinol, formaldehyde solution prepares the resol that obtains and vinyl-pyridine latex, natural rubber latex is as the main body of dipping solution, canvas is made to have good snappiness, enhance the bond properties between casing ply and rubber layer, extend the work-ing life of conveying belt, improve the accuracy that conveying belt transmits.
