Description
Technical field
It is specially a kind of for coating the thermoplastic elastomehc of glass fiber enhanced nylon the invention belongs to technical field of polymer materials
Elastomer material and preparation method thereof.
Background technique
Nylon is a kind of widely used engineering plastics, has many advantages, such as high mechanical strength, and heat resistance, rub resistance are good.
In recent years, nylon is widely used in toy, daily necessities, industrial products etc., product surface made of nylon material it is often harder and
Smooth, feel is poor in use, and is easy to slide.To solve this problem, upper one layer can be coated on nylon surface
Flexible glue makes it have good feel, increases the comfort of user, can also largely improve the aesthetics of product.
The products such as electric tool and pneumatic tool can generate biggish vibration in use, the thermoplasticity coated on nylon handle
Elastomer can play the role of damping, play preferable protective effect.
Common thermoplastic elastomer (TPE) (TPE) encapsulated products mainly have the encapsulated polypropylene of TPE (PP), TPE encapsulated in the market
Acrylonitrile-butadiene-styrene copolymer (ABS), the encapsulated nylon of TPE (PA), wherein due to the polarity and TPE material phase of nylon
Difference is larger, so encapsulated difficulty is maximum, the encapsulated difficulty of the PA material of fiberglass reinforced is further up.
Have the defects that TPE is Nian Jie with PA material loosely mostly in the prior art, the TPE material of cladding is easier to from PA base
It removes or falls off on material.Overlap, the defect ware etc. that TPE cover material product generates in process, need the TPE cladding
It is coated again after material removing, the product coated is frequently necessary to recycling secondary use, the existing encapsulated stronger TPE product of performance
A large amount of TPE flexible glue can be remained on substrate when removing PA substrate, the complexity for becoming recovery process reduces nylon products
The rate of recovery.Patent CN103897321A discloses a kind of TPE material of low temperature cladding nylon, the product can 220 DEG C plus
It is bonded nylon at a temperature of work, but a large amount of TPE residual layer can be generated on substrate in stripping process, and to the Buddhist nun of fiberglass reinforced
Dragon does not almost have bonding force.Patent CN103756234A discloses a kind of encapsulated nylon material of TPE for removing noresidue, but it is bonded
Power is limited, and does not almost have bonding force to the nylon of fiberglass reinforced.Patent CN102432976A, which discloses one kind, can coat glass increasing
The thermoplastic elastic of strong nylon, but the product is needed with dimethylbenzene, n-butanol, cyclohexanone mixed liquor before quadric injection mould to nylon
Part carries out spraying pretreatment, and process is complicated, greatly reduces production efficiency, and only to low content glass fiber enhanced nylon (glass
Fine content 25%) there is certain cladding power, it is poor to the cladding power of high-content glass fiber enhanced nylon, it is difficult to practical application.Patent
CN101921444A discloses a kind of removing noresidue, the tack-free special material coated on nylon in surface, but the melting of the product refers to
Number is lower, will lead to the poor mobile performance of the product, needs in process of production big to generate using biggish injection pressure
The overlap of the amount injection defect product more with appearance.
Summary of the invention
Have the defects that TPE is Nian Jie with PA material loosely for solution is of the existing technology, the TPE material of cladding is easier to
The defect removed or fallen off from PA substrate, the present invention provide a kind of for coating the thermoplastic elastomer (TPE) material of glass fiber enhanced nylon
