3. material will have enough toughness and anti-fatigue ability, can resist the continuous impact of larger particles in material and not damage.
Therefore, the present invention proposes the wearing and tearing of a kind of Novel slurry pump and repairs abrasion-resistant coating material, and this material comprises:
Host, comprises epoxy resin 15-60 part, coupling agent 0-5 part, toughner 0-20 part, abrasive material 0-600 part, fiber 0-60 part, resin alloy polyphenylene oxide 0-80 part, antifriction material 0-30 part, thixotropic agent aerosil 0-20 part, pigment 0-50 part;
Solidifying agent, comprises organic amine substance 5-50 part, coupling agent 0.5-20 part, promotor 0.5-18 part, abrasive material 0-300 part, thixotropic agent aerosil 0-10 part, pigment 0-15 part.
Host in the present invention and solidifying agent are configured separately in preparation process, and various component forms through Homogeneous phase mixing.During onsite application, then host and solidifying agent are carried out used in combination.
Wherein, coupling agent can select KH550, KH560 or other coupling agent; Promotor can select DMP-30 or other promotor.
Under preferable case, during use, the proportioning of host and solidifying agent is 3: 1 ~ 4: 1.
