Description

A kind of environment-friendly type extrusion sheet and its manufacturing method
Technical field
The present invention relates to Material Field more particularly to a kind of environment-friendly type extrusion sheet and its manufacturing methods.
Background technology
Requirement standard with automobile industry to smell VOC is continuously improved, and mark is not achieved with the material of EVA base materials in tradition Standard, EVA are referred to as vinyl acetate, and production material is mainly toluene, ethylene and acetate ethylene copolymer synthesis, so generating gas Taste and Residual Toluene object cause smell and VOC that vehicle enterprise environmental protection standard is not achieved always, and PE colorless and odorless, POE enhancings vulcanize, For this purpose, a large number of experiments has also been made in my company, so using the materials such as POE, PE, the base-material of production sheet material at present is just selected, is reached It is compared for the sheet material of base material to the requirement of vehicular odor and VOC, and by the sheet material improved and EVA.It is obviously base with PE, POE The product of material is better than the characteristic that EVA is base material.
Invention content
The shortcomings that present invention for smell and Residual Toluene object is generated in the prior art, provides a kind of environment-friendly type extrusion sheet And its manufacturing method.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
A kind of environment-friendly type extrusion sheet, including following components by weight：
10 parts of POE
20 parts of PE
1~2 part of bulking agent
20~40 parts of fillers
1~3 part of vulcanizing agent
POE is DuPont-Dow elastomers company of the U.S. in 1994 with ethylene, pungent dilute for raw material, using in-situ polymerization work The new type polyolefin elastomeric material that skill (INSITE) and constrained geometry catalysis technique (CGCT) are made and release.Polyethylene (PE) it is in itself a kind of material of crystallization, but since the intervention of octene in strand or butylene destroys the knot of part polyethylene The polyethylene segment that crystalline substance, octene or butylene segment are destroyed with crystallization together forms the soft segment of elasticity, the crystallization unit of polyethylene Divide and form hard section, plays a part of physical crosslinking point, POE is made to be provided with the property of elastomer.The material of the two mixing manufacture was both There are good elasticity, damping noise reduction to make good use of, while reducing the pollution to environment.
Preferably, bulking agent is PE-g-MAH.PE-g-MAH is maleic anhydride grafted polyethylene, is to pass through chemical reaction Means the several maleic anhydride molecules of skill are connect on polyethylene molecular chain, can make product both with polyethylene good workability and Other excellent properties, but with maleic anhydride polar molecule can again reactivity and it is highly polar.After PE-g-MAH bulking agents are added, It can make system while keeping higher level toughness, the reduction of effective compensation modulus makes POE be better mixed with PE.
Preferably, filler is white carbon.
Preferably, vulcanizing agent is cumyl peroxide.
A kind of production method of environment-friendly type extrusion sheet, includes the following steps：
(1) constituent content according to claim 1 weighs 10 parts of POE and 20 part of PE, first adds in 1~2 part of mass fraction The bulking agent of a quarter stirs 1~2min, and 20~40 parts of fillers and 1~3 part of vulcanizing agent is being added, is adding mass fraction 1 All components are added mixer and carry out mixing by 3/4ths bulking agent in~2 parts, and mixing while stirs component It mixes overturning and obtains mixture；
(2) single screw rod is put into the feed inlet of extrusion equipment, mixture is added to feed inlet, mixture passes through screw rod Rotate into equipment；
(3) it squeezes out at raw rubber to the extrusion die of the thickness mixed up, the extrusion temperature of raw rubber is 170 DEG C~180 DEG C；
(4) using three rollers of extrusion equipment as traction, raw rubber is transferred on flowing water line platform, transfer while carries out cold But；
(5) extrusion sheet is obtained to cutting into required size after raw rubber progress surface corona processing.
Bulking agent is added at twice, addition bulking agent, POE, PE keep mixing more uniform for the first time, in order to avoid preliminary heat release shadow The property of bulking agent is rung, second of addition bulking agent makes POE and PE materials preferably mix.
Preferably, the time of component mixing in mixer is 6~7 minutes, the refractory bricks of mixing slot in mixer At 180~200 DEG C.Since the melt temperature of PE is at 160~165 DEG C, and the melt temperature of POE is at 90 DEG C or so, therefore mixing The temperature of heating is higher than 165 DEG C, and the extrusion temperature of raw rubber is also higher than 165 DEG C, but the excessively high drop that can cause raw material of temperature Solution influences the generation of product, therefore the refractory bricks of control mixing slot, at 180~200 DEG C, the extrusion temperature of raw rubber is 170 DEG C ~180 DEG C.
The present invention has significant technique effect as a result of above technical scheme：The sheet material produced reaches automobile-used The requirement of smell and VOC, and the sheet material improved and EVA are compared for the sheet material of base material, hence it is evident that with the production that PE, POE are base material Product are better than the characteristic that EVA is base material.
