Abstract
The invention relates to a slow-binder for a steel stranded wire, which is prepared by adopting the following components according to parts by weight: 30-45 parts of orthocresol formaldehyde poly-epoxy resin, 10-15 parts of polycarboxylic acid, 5-30 parts of alicyclic polyamide fiber and 100-160 parts of filler. The slow-binder has the benefits of having good adhesiveness at the earlier stage and extremely high strength in solidification at the later stage, and simultaneously having good toughness and strong binding power.
Description
Technical field
The present invention relates to the sticker field, especially relate to the slow sticker that a kind of steel strand are used.
Background technology
The frictional coefficient that the existing unbonded prestressing tendon of slow-adhesion prestress steel strand is had is little, without advantages such as grouting after service sleeve and the stretch-draw; After coating solidifies through certain hour; Because the PE jacket surface is pressed with ripple; Making slow-adhesion prestress steel strand be equivalent to bonded prestressed tendon, is the new selection of prestressed material from now on.Since slow-adhesion prestress steel strand diameter ratio have the bonding or the unbonded tendon diameter big; Single delayed bonding prestressed tendon cross section is big; The prestress tonnage is relatively also big, and is all very suitable for the structures such as pressurized vessel of large-tonnage railway, bridge, traffic, water conservancy, nuclear power plant containment shell, Large Storage Tanks coal, air storage, water storage.
For slow bonding steel strand, the quality of slow sticker directly affects construction quality.Present stage, the prescription of slow sticker is varied, and it is poor that effect also has.
Summary of the invention
The slow sticker that the present invention provides a kind of steel strand to use.
For realizing above-mentioned goal of the invention, the technical scheme that the present invention takes is following:
The slow sticker that a kind of steel strand are used is made up of the component of following parts by weight: many epoxy resin of ortho-cresol formaldehyde type 30-45 part, poly carboxylic acid ether 10-15 part, aliphatic cyclic amine 5-30 part, filler 100-160 part.
Wherein, described filler is one or both of lime carbonate, quicklime, cement or talcum powder kind.
Preferred version: many epoxy resin of ortho-cresol formaldehyde type 35-40 part, poly carboxylic acid ether 12-15 part, aliphatic cyclic amine 20-26 part, filler 120-140 part.
The invention has the beneficial effects as follows: slow sticker of the present invention has good tack in earlier stage, has high intensity after the cured, has good toughness simultaneously, and cohesive force is strong.
Embodiment
Below in conjunction with embodiment, to details are as follows according to embodiment provided by the invention:
Embodiment 1
The slow sticker that a kind of steel strand are used accurately takes by weighing the component of following weight: 35 kilograms of the many epoxy resin of ortho-cresol formaldehyde type, 12 kilograms in poly carboxylic acid ether, 26 kilograms of aliphatic cyclic amines, 130 kilograms of fillers.
Embodiment 2
The slow sticker that a kind of steel strand are used accurately takes by weighing the component of following weight: 30 kilograms of the many epoxy resin of ortho-cresol formaldehyde type, 10 kilograms in poly carboxylic acid ether, 7 kilograms of aliphatic cyclic amines, filler double centner.
Embodiment 3
The slow sticker that a kind of steel strand are used accurately takes by weighing the component of following weight: 45 kilograms of the many epoxy resin of ortho-cresol formaldehyde type, 15 kilograms in poly carboxylic acid ether, 30 kilograms of aliphatic cyclic amines, 160 kilograms of fillers.
Preparing method: each component among the embodiment 1 is mixed after stirring, grinding, process pasty state, promptly get and delay the sticker finished product.Slow sticker according to the inventive method preparation has good flowability, tack and toughness, has HS, characteristics that cohesive force is big simultaneously.
Claims (3)
1. the slow sticker that steel strand are used is characterized in that being made up of the component of following parts by weight: many epoxy resin of ortho-cresol formaldehyde type 30-45 part, poly carboxylic acid ether 10-15 part, aliphatic cyclic amine 5-30 part, filler 100-160 part.
2. according to the described slow sticker of claim 1, it is characterized in that: described filler is one or both of lime carbonate, quicklime, cement or talcum powder kind.
3. according to claim 1 or 2 described slow stickers, it is characterized in that: many epoxy resin of ortho-cresol formaldehyde type 35-40 part, poly carboxylic acid ether 12-15 part, aliphatic cyclic amine 20-26 part, filler 120-140 part.
