Abstract
The invention discloses a kind of treated basalt fiber/styrene-butadiene latex composite foam materials and preparation method thereof, it prepares raw material and parts by weight includes: 100 parts of carboxylic styrene butadiene latex, 10 parts~15 parts of cationic chloroprene latex, 10 parts~15 parts of butadiene-vinylpyridine copylymer latex, 5 parts~10 parts of treated basalt fiber, 3 parts~7 parts of foaming agent, 2 parts~5 parts of vulcanizing agent, 1 part~3 parts of vulcanization accelerator；The method of modifying of treated basalt fiber: basalt fibre is impregnated in the concentrated sulfuric acid and obtains sulfonation basalt fibre；Polyacrylamide is dissolved in water and obtains polyacrylamide solution；Sulfonation basalt fibre is impregnated in polyacrylamide solution, obtains the treated basalt fiber through 50 DEG C~60 DEG C isothermal curings and 300 DEG C~400 DEG C isothermal holdings.Treated basalt fiber of the present invention/styrene-butadiene latex composite foam material excellent product performance, product stability is good, is expected to be widely used in sole material field, prospect is outstanding.
Description
Technical field
The present invention relates to technical field of polymer processing, and in particular to a kind of treated basalt fiber/styrene-butadiene latex is compound
Foamed material and preparation method thereof.
Background technique
Carboxylic styrene butadiene latex is to add a small amount of carboxylic acid and other auxiliary agents with butadiene, styrene, is generated by emulsion polymerization
Copolymer.Due to the introducing of carboxyl, the polarity of latex is increased, carboxy styrene-butadiene rubber dairy products have than styrene-butadiene latex product more
Excellent wear-resisting, heat-resisting, ageing-resistant performance, can also be used in combination with natural rubber and various synthetic rubber, be expected to as sole material
Material is widely applied.Currently, the research for carboxylic styrene butadiene latex foamed material is also rarely reported.
But the defects of carboxylic styrene butadiene latex still has tensile resistance, wear-resisting property and ingredient compatibility performance are poor, it would be highly desirable to
It solves, therefore, in practical applications, it usually needs carboxylic styrene butadiene latex is modified to improve the product of latex product
Energy.Common method of modifying includes: filler modified and chemical modification.
Cationic chloroprene latex has preferable oil resistant, ageing-resistant, corrosion resistance, also has preferable stretch-resistance
Can, it can be used in combination with carboxylic styrene butadiene latex, to enhance the properties of product of carboxy styrene-butadiene rubber dairy products.
Basalt fibre is basalt building stones after 1450 DEG C~1500 DEG C meltings, passes through platinum-rhodium alloy bushing high speed
Continuous fiber made of drawing has a variety of excellent properties such as tensile strength height, good insulating, wear-resisting, corrosion-resistant, is a kind of good
Good rubber reinforcement material.But since basalt fibre surface is smooth, surface-active is lower, with rubber material compatibility compared with
Difference limits it in the application of rubber materials, needs to be modified basalt fibre processing.
Currently, common basalt fibre method of modifying is surface roughness or the surface to improve basalt fibre
For the purpose of activity, most commonly seen is the method for coupling agent modified basalt fibre.But there is also idols for coupling agent modified method
The problems such as modified effect caused by connection effect is unstable is bad.
Chinese patent CN201711222315.0 discloses a kind of basalt fibre rubber soles and preparation method thereof, the rubber
Rubber sole is prepared by the raw material of following parts by weight: 20~30 parts of natural rubber, 40~60 parts of neoprene, and butadiene-styrene rubber 20
~29 parts, 1.5~2.0 parts of sulphur, 35~46 parts of basalt fibre, 4~5 parts of calcium carbonate, 0.6~1.2 part of stearic acid, aftereffect promotees
Into 0.5~1.1 part of agent, 3~6 parts of nanometer calcium, TM monex TM0.22~0.35 part, 1.7~2.6 parts of diethylene glycol (DEG), superfine active
22~29 parts of calcium carbonate, 6~8 parts of white factice, 0.7~1.1 part of silane coupling agent, 6~9 parts of naphthenic oil, antioxidant 0.35~
0.45 part, 0.6~1.0 part of antioxidant SP-C, 0.5~0.9 part of paraffin, 0.5~1.1 part of modified rosin resin.But the patent
The basalt fibre of use is not modified, and surface-active is poor, poor with rubber material compatibility, reinforcing effect compared with
Difference.
Chinese patent CN201811575761.4 discloses a kind of treated basalt fiber rubber composite material preparation method:
It weighs basalt fibre to be put into large beaker, is poured slowly into glacial acetic acid, stirred using electric mixer, disperse basalt fibre
It opens, stops stirring and take out basalt fibre from beaker, filter vacuum drying after cleaning, obtain treated basalt fiber；
Natural rubber is weighed, after being plasticated using opening rubber mixing machine, treated basalt fiber is sequentially added, zinc oxide, stearic acid, prevents always
Agent 4020NA, accelerator NS, carbon black, Vulcanization accelerator TMTD and sulphur are kneaded standing and obtain rubber compound；Rubber compound obtained is used
Vulcanizing press is vulcanized, and treated basalt fiber/native rubber composite material is obtained.But the patent basalt is only used
Acid etching increases the surface roughness of basalt fibre, but it improves basalt fibre and the compatibility effect of rubber material and has
Limit.
Therefore, it is necessary to a kind of composite foam materials of treated basalt fiber enhancing styrene-butadiene latex, improve composite foamed material
The performances such as tensile resistance, wear-resisting property, the corrosion resistance of material.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of treated basalt fiber/styrene-butadiene latex composite foam material and its system
Preparation Method.
Technical solution used by the present invention solves the above problems is: a kind of treated basalt fiber/styrene-butadiene latex is compound
