Abstract
This invention relates to a finger-pressing flexible sealant for sealing metal holes and gaps. The finger-pressing flexible sealant comprises: thermoplastic resin 15-25 wt.%, viscous resin 3-6 wt.%, filler 5-15 wt.%, slip agent 10-15 wt.%, manipulating agent 5-10 wt.%, reinforcer 15-30 wt.%, surfactant 1-5 wt.%, and plasticizer 20-30 wt.%. The finger-pressing flexible sealant can be directly manipulated by hand, and has no odor or toxicity. The finger-pressing flexible sealant does not stick hand, and can effectively seal metal holes and gaps while can maintain enough flexibility to absorb applied stress. Besides, the finger-pressing flexible sealant has such advantages as good processability, no flowing and convenient usage.
Description
Technical field
The present invention relates to a kind of sealing agent, particularly a kind of finger pressure type softness sealant more particularly, the present invention relates to a kind of metal aperture, position, crack, the particularly bonding tackiness agent of privileged sites such as slit, arrangements for automotive doors edge, fabrication hole of being used for.
Technical background
Past has the metal joint and the seam crossing that must seal in the body of a motor car manufacturing processed, what adopt is that the pasty state sealing agent seals, PVC type pasty state sealing agent bonding strength height, effective to general less gap sealing, but require the very high big fabrication hole of performance, big slit to be difficult to reach requirement with the pasty state sealing agent for seal construction, can not guarantee sealing effectiveness, be difficult for being coated with as the front windshield pillar of truck cab and top cover gutter channel flanging junction and use the pasty state sealing agent.
Summary of the invention
The purpose of this invention is to provide a kind of finger pressure type softness sealant composition, to solve the above-mentioned problems in the prior art, good with this finger pressure type softness sealant composition of the present invention and metallic substance adhesion property, when guaranteeing enough bonding strengths and excellent sealing, also has good manual operations.Can with the encapsulant composition moulding, be placed on required place compacting, floating with hand according to concrete hole, crack size and Special Circumstances, appearance effect is good, and is tack-free in the construction process, nontoxic, tasteless.
Technical scheme of the present invention is: a kind of finger pressure type softness sealant is the composition of forming by weight percentage, and its component is formed and comprised:
Thermoplastic resin 15～25%
Tackifying resin 3～6%
Weighting agent 5～15%
Slipping agent 10～15%
Operation agent 5～10%
Strengthening agent 15～30%
Promoting agent 1～5%
Softening agent 20～30%
Finger pressure type softness sealant characteristics of the present invention are to can be used for discontinuous metal aperture, the sealing at position, crack, can use the hand direct control during use, nontoxic, tasteless, tack-free, can more effectively be used to prevent entering of materials such as dust, moisture content, and good manufacturability, do not trickle, easy to use.
