Description
Technical field
The present invention relates to connector technical field, and in particular to a kind of automobile waterproof high tenacity function connects part and its system
Preparation Method.
Background technology
Connector makes a kind of structure very common in mechanical field, and the connector requirement of automobile has higher anti-tensile
Property, wearability, bending resistance and impact strength and higher extensibility, often by raw material of metal, manufacture is connected in traditional handicraft
Part.But the weight of metal connecting piece is very big, and it is easy to the shortcoming poor with toughness of getting rusty that absorb water.
A kind of connector is disclosed in Patent No. CN201510112357.3 documents, although this connector
Will be with mechanical strength be excellent and hardness is high a little, but it there is poor water proofing property, poor impact toughness and tensile strength is low asks
Topic.
The content of the invention
A kind of automobile waterproof high tenacity function connects part prepared for above-mentioned problem, the present invention, with anti-
Water function, high tenacity and the high advantage of tensile strength.
To achieve the above object, the present invention uses following technical scheme：
A kind of automobile waterproof high tenacity function connects part, its composition is by weight:40~50 parts of modified polyvinylalcohol,
25~30 parts of polyethylene, 15~20 parts of butadiene-styrene rubber, 12~17 parts of phenol-formaldehyde resin modified, 20~25 parts of asphalt, bamboo charcoal are fine
9~16 parts of dimension, 8~14 parts of paraffin, 5~9 parts of sodium pyrophosphate, 6~11 parts of vermiculite power, 4~10 parts of calcium oxide powder and antioxidant 3
~8 parts.
It is preferred that, the manufacture method of the modified polyvinylalcohol comprises the following steps：Polyvinyl alcohol is dissolved in 80~90 DEG C
Distilled water in, and add 4, the 4- diphenyl diglycidyl ethers that quality is polyvinyl alcohol 45% heat while stirring 20~
35min, it is polyvinyl alcohol 8~12% that acrylamide and quality that quality is polyvinyl alcohol 10~15% are then added thereto
Plasticizer, adds the acetic acid that quality is polyvinyl alcohol 13%, is configured to solution after being sufficiently mixed；Constant temperature is stirred under conditions of 85 DEG C
30~45min is mixed, 26~38h is then dried at room temperature for, modified polyvinylalcohol is obtained.
It is preferred that, the manufacture method of the phenol-formaldehyde resin modified comprises the following steps：By phenolic resin, the fat of silicic acid third and receive
It is phenolic resin, the fat of silicic acid third and nano-cerium oxide that rice cerium oxide adds quality thereto according to certain mass than mixing, then
The sodium hydroxide solution that twice of three's gross mass, is reacted under conditions of 90 DEG C, to when continuing to generate without pink solid, is taken
Go out hard resin and obtain phenol-formaldehyde resin modified after being rinsed with water.
It is preferred that, the preparation method of the connector comprises the following steps：
A, by bamboo-carbon fibre, polyethylene, butadiene-styrene rubber, phenol-formaldehyde resin modified, paraffin, sodium pyrophosphate, vermiculite power, calcium oxide
Powder and antioxidant are ground processing respectively, and kneader mediates 15~30min to obtain modified materials standby at 160~180 DEG C；
B, modified materials are well mixed with remaining raw material after, on the twin screw extruder melting extrusion granulation after produce thing
Material, each silicon carbide of extruder is 220~235 DEG C, 210~230r/min of extruder rotating speed；
C, by resulting material shaping be connector finished product.
It is preferred that, the mass ratio of the phenolic resin, the fat of silicic acid third and nano-cerium oxide is 9:1:1.
It is preferred that, the antioxidant selects TBHQ.
It is preferred that, the plasticizer selects sorbierite.
Using above-mentioned technical scheme, the beneficial effect that the present invention reaches is：
1st, phenolic resin is modified by the fat of silicic acid third and nano-cerium oxide, the fat of silicic acid third in the basic conditions with phenol
Phenolic hydroxyl group in urea formaldehyde occurs esterification and has blocked part phenolic hydroxyl group, while occurring cocondensation with the benzyl hydroxyl in phenolic resin
It is poly- to react the coefficient of expansion for reducing product, the increase of its thermal conductivity factor is enhanced the heat resistance of phenolic resin.Nano oxygen
Changing the addition of cerium makes the Crack Extension of phenolic resin be obstructed and be passivated, and finally terminates crackle, phenolic resin is developed into brokenly
Bad property ftractures.Constantly it is crosslinked between the chain of modified phenolic resin, ultimately forms random network structure, improve
The toughness and tensile resistance of phenolic resin.
2nd, the amino in acrylamide can consume the hydrophilic group in polyvinyl alcohol with the hydroxyl reaction in POLYPROPYLENE GLYCOL
Group, improves the hydrophobic performance of propenyl.Avoid connector in a humidity environment, the destruction due to moisture to connector,
Extend the service life of connector.In addition, 4,4- diphenyl diglycidyl ethers make POLYPROPYLENE GLYCOL with polyvinyl alcohol reaction
Structure shows as dimensional network structure, because the chemical bond between stereochemical structure is more, and is cross-linked, so as to improve poly-
The chemical stability of vinyl alcohol.
