Problems solved by technology

[0004] This patent functionalizes the surface of graphene, so that graphene has good solubility in non-polar solvents and polar solvents, so that the functionalized graphene has good solubility and is uniformly dispersed in the emulsion; currently , the application of graphene's damping performance has not been reported yet. This patent combines functionalized graphene with polymer emulsion to give full play to the damping characteristics of the two, and prepares an environmentally friendly high-performance damping slurry for vehicles.

Embodiment Construction

[0041] The present invention will be further explained below in conjunction with specific examples.

[0042] According to the formula described in Table 1,

[0043] Sieve bentonite, fumed silica, nano-calcium carbonate, functionalized graphene, and nano-silver powder, and use a 100-200 mesh sieve to blend the core-shell emulsion, defoamer, plasticizer, and cross-linking agent, and stir Evenly, add the powder sieved in the above steps into the blended emulsion, use mechanical stirring to mix, room temperature, stirring speed 100~200r / min, add deionized water, adjust the consistency to 8~10.

[0044] Prepare functionalized graphene according to table three formulations:

[0045] Functional graphene treatment method: Weigh a certain amount of graphene, dissolve it in DMF, disperse it ultrasonically, slowly add the purified monomer dropwise under magnetic stirring, add the initiator, continue to react for 3~4h after the dropwise addition, filter, and dry Preparation of functionali...

Abstract

The invention relates to a preparation method of an automotive damping material and mainly relates to a high-performance damping slurry filled withe functionalized graphene and a preparation method of the high-performance damping slurry. The preparation method comprises the steps of sieving bentone, fumed silica, nano calcium carbonate, functionalized graphene, nano-silver powder by use of a sieve of 100-200 meshes, blending a core-shell emulsion, a defoamer, a plasticizer and a cross-linking agent, stirring evenly, adding the sieved powder to the blended emulsion, mixing by virtue of mechanical stirring at a normal temperature and a stirring speed within the range of 100-200r/min, and adding deionized water for regulating the thickness to the range of 8-10. The functionalized graphene has excellent solubility with a polymer matrix; due to frictional loss between the functionalized graphene and the polymer matrix due to interfacial slippage, the energy can be effectively dissipated, and the noise pollution in a vehicle can be effectively reduced; meanwhile, the silver nanomaterial is taken as an antimycotic assistant, and has an excellent antimycotic effect.

Description

technical field [0001] The patent of the present invention relates to a method for preparing automobile damping materials, mainly involving high-performance damping slurry with functionalized graphene as filler and its preparation method. Background technique [0002] With the improvement of people's living standards, the requirements for quality of life are getting higher and higher. Cars have generally entered every family, but subsequently, the requirements for car comfort are getting higher and higher; vehicle noise mainly comes from wheel and rail noise, vehicle non-dynamic noise, vehicle equipment noise and air dynamic noise, etc. Ambient noise outside the vehicle. The problem of vibration and noise inside the vehicle has not attracted enough attention, but with the lightweight of the vehicle, the comfort of the vehicle and the comfort of the acoustic environment have become an important factor affecting the competitiveness of the vehicle industry; how to reduce the n...
