Abstract
The invention discloses a road traffic marking plate material and a preparation method thereof. The road traffic marking plate material comprises the following components by weight: 100 parts of polypropylene, 10-16 parts of high density polyethylene, 10-16 parts of ethylene propylene terpolymer, 10-20 parts of glass fiber, 0.1-0.3 part of titanium tris (dodecylbenzenesulfonate) isopropoxide and 0.1-0.2 part of molybdenum dioxide. The titanium tris(dodecylbenzenesulfonate) isopropoxide is used for modification on glass fiber; then the glass fiber is added together with polypropylene, high density polyethylane, ethylene propylene terpolymer and molybdenum dioxide into a high-speed mixer for mixing; and the mixture is subjected to extrusion and granulation by an extruder. The road traffic marking plate material provided by the invention has the advantages of high heat resistance temperature, good thermal stability, high MFR value, tensile strength, bending modulus and cantilever beam notched impact strength.
Description
Technical field
The present invention relates to a kind of matrix material and preparation method thereof, relate in particular to a kind of road traffic sign plate material and preparation method thereof.
Background technology
Road signs and graticule are to transmit traffic management information with pattern, symbol, word, in order to a kind of security control facility of control and channel traffic.Road equipment with word or symbol transmission guiding, restriction, warning or indication information.Claim again road sign, road signs.It is to implement traffic administration that eye-catching, clear, bright traffic sign is set, and guarantees traffic safety, important measures smoothly.
Traffic sign has broad variety, can divide in various manners: item key and Subsidiary Signs; Movable sign and fixed sign; Simulated log, luminous sign and reflecting sign; And the changeable-message sign of reflection environment variation.
Traffic sign is classified according to optical characteristics, is divided into reflex reflection formula, illuminated and illuminated three kinds, wherein illuminated interior lighting formula and the exterior lighting formula of being divided into again.
Road signs product comprises road traffic sign plate and strut member, and wherein road traffic sign plate is the assembly consisting of mark slab, plate face and chute, rivet etc.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention is to provide a kind of road traffic sign plate material.
Two of technical problem to be solved by this invention is to provide a kind of preparation method of road traffic sign plate material.
Technical problem to be solved by this invention, is achieved by the following technical solution:
A kind of road traffic sign plate material; by following component, formed by weight: 100 parts of polypropylene; high density polyethylene(HDPE) 10-16 part; terpolymer EP rubber 10-16 part; glass fibre 10-20 part; sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester 0.1-0.3 part, molybdenum dioxide 0.1-0.2 part.
The preparation method of above-mentioned road traffic sign plate material, is comprised of following step: by sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester, glass fibre is carried out to surface modification treatment; Add in super mixer and stir together with molybdenum dioxide with polypropylene, high density polyethylene(HDPE), terpolymer EP rubber again, through forcing machine extruding pelletization, can make road traffic sign plate material of the present invention.
Road traffic sign plate material of the present invention, has higher heat resisting temperature, good thermal stability, higher MFR value, draws high intensity, modulus in flexure and socle girder notched Izod impact strength.
Embodiment
Below by specific embodiment, the invention will be further described, but the present invention is not limited by following examples.
Embodiment 1
Take: 100 kilograms of polypropylene, 13 kilograms of high density polyethylene(HDPE)s, 13 kilograms of terpolymer EP rubbers, 15 kilograms, glass fibre, 0.2 kilogram of sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester, 0.15 kilogram of molybdenum dioxide.
By sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester, glass fibre is carried out to surface modification treatment; Add in super mixer and stir together with molybdenum dioxide with polypropylene, high density polyethylene(HDPE), terpolymer EP rubber again, through forcing machine extruding pelletization, can make road traffic sign plate material of the present invention.
Wherein, with coupling agent, glass fibre is carried out to surface modification treatment: under high-speed stirring, rotating speed is 1500-3000r/min by glass fibre, spray into coupling agent sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester; then continue to stir 5-15 minute, obtain modified glass-fiber.
The present embodiment polypropylene used is Co-polypropylene, and the trade mark is J641, and Guangzhou petrochemical industry branch office of China Petrochemical Industry produces.
