Abstract
The invention discloses a production method of an automobile damping mat, and belongs to the field of rubber mat technology. The production method successively comprises steps of raw material mixing, internal mixing and stirring, extruding, twisting, compositing, die forming and packaging. The automobile damping mat comprises following raw materials, by weight, 9 to 11 portions of butyl rubber, 21 to 27 portions of polybutene, 18 to 24 portions of talc, 6 to 8.4 portions of light calcium, 16 to 20 portions of bentonite, 0.4 to 0.6 portion of an anti-aging agent, 5.2 to 7.1 portions of barium sulfate and 9 to 11 portions of white oil. Large-scaled production of the automobile damping mat can be realized. The automobile damping mat possesses excellent performances, no toxicity and no smell, is harmless, and is friendly to the environment.
Description
Technical field:
The present invention relates to the rubber pad technical field, specifically a kind of car damping pad production method.
Background technology:
The rubber pad pattern is various, and majority is to be made with rubber, and the car damping pad is a kind of of numerous rubber pads, existing car damping pad be all to refer and synthesize other elastomeric material and stopping composition carries out the extrusion moulding by pitch.
The chocolate complex mixture that pitch is comprised of hydrocarbon polymer and the nonmetal derivative thereof of different molecular weight, be in a liquid state, semi-solid state or solid-state, is a kind of waterproof and dampproof and rot-resistant organic gel gel material.For the industry such as coating, plastics, rubber and surfacing etc.Pitch has moderate toxicity, irritating smell.Pitch and flue gas thereof have a pungency to mucocutaneous, and light toxic action and carcinogenesis are arranged.
Existing car damping pad is due to pitch being arranged in raw material, therefore there is certain toxicity, HUMAN HEALTH is had to adverse influence, and existing car damping pad all has certain pungency taste, because the car damping pad is the inside that is used in automobile bodies, high-grade car, new car, because its stopping property is relatively good, irritating smell is heavier, and in compartment, be also the place of the long contact of people, the disadvantageous effect that HUMAN HEALTH is caused is more serious.And pitch has certain fragility, use pitch for raw material production damping mat out is harder, easily split frangible.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of production method that can produce nonpoisonous and tasteless, not easily broken car damping pad.
The technical problem solved adopts following technical scheme:
A kind of car damping pad production method, comprise successively that raw material mixes, pure, compound, die forming is stirred, extrudes, rubs with the hands in banburying and packaging step, it is characterized in that: described raw material mixing comprises the white oil that isoprene-isobutylene rubber that weight part is 9～11, polybutene, weight part that weight part is 21～27 are 18～24 talcum powder, the weight part fine particle calcium carbonate that is 6～8.4, weight part is 16～20 wilkinite, anti-aging agent that weight part is 0.4～0.6, barium sulfate that weight part is 5.2～7.1 and weight part are 9～11.
Described material mixing is first to put into polybutene, while stir, puts into successively other raw material.The mixing that mixing can be full and uniform like this.
Describedly compoundly refer to that the two sides to extruding and rub with the hands the rubber pad after net formed carries out composite protection film.There is the effect of grease proofing, anti-gray and waterproof, during production and application, protective membrane is being removed.
It on the rubber pad two sides is respectively aluminium foil and separate-type paper that described protective membrane is compounded in.Aluminium foil, as wrapping material, has nontoxic, tasteless benefit, and not yielding, after recyclable processing, recycles.Separate-type paper is a kind of prepreg adhesion that prevents, can protect again the not contaminated separate paper of prepreg, low price.
Described die forming refers to the mould designed the product after compound is cut.Can product directly be processed into to the required shape of client according to client's requirement, facilitate client's use.
In the present invention, isoprene-isobutylene rubber and polybutene be as the main raw material of car damping pad, all has nontoxicly, and tasteless or the material of slight smell is arranged, and is the excellent material of replacing asphalt.Talcum powder is the effect of playing filling, and anti-aging agent weaving car damping pad aging extends its work-ing life, and barium sulfate plays the effect of reinforcement, and white oil plays the effect of blast and the demoulding.
The invention has the beneficial effects as follows: the present invention can large-scale production, and the car damping pad of producing, have good performance, and nontoxic, tasteless, harmless, health environment-friendly.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific examples, further set forth the present invention.
A kind of car damping pad production method, comprise successively that raw material mixes, pure, compound, die forming is stirred, extrudes, rubs with the hands in banburying and packaging step, it is characterized in that: described raw material mixing comprises the white oil that isoprene-isobutylene rubber that weight part is 10.5, polybutene, weight part that weight part is 25.3 are 21.7 talcum powder, the weight part fine particle calcium carbonate that is 7.6, weight part is 18 wilkinite, anti-aging agent that weight part is 0.5, barium sulfate that weight part is 6.4 and weight part are 10.
Material mixing is first to put into polybutene, while stir, puts into successively other raw material.Compoundly refer to that the two sides to extruding and rub with the hands the rubber pad after net formed carries out composite protection film.It on the rubber pad two sides is respectively aluminium foil and separate-type paper that protective membrane is compounded in.Die forming refers to the mould designed the product after compound is cut.
The product that the present embodiment is produced is after strict detection, content and 18 kinds of PAHs content summations of inner objectionable impurities benzo [a] pyrene all are less than 0.2mg/kg, reach a class health level (can put into mouth material and for children's use once in three years old, understand the toy material with skin contact).Concrete detection method and the following list of data:
Detect foundation:
| Test item | Testing method | Testing tool |
| Polycyclic aromatic hydrocarbons (PAHs) | GS?ZEK01.4-08 | GC-MS |
Detected result:
Annotation:
N.D.=does not detect
Mg/kg=1,000,000/.
Testing process: the weighing sample in test tube → with organic solvent extraction → concentrated extract → transfer extraction liquid to volumetric flask → with organic solvent constant volume → analyze with GC-MS.
Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
