Abstract
The invention relates to a method for producing linear low-density polythene grass pad. Wherein, it uses linear low-density polythene grass pad as material, uses industrial dope; and the production comprises that mixing materials, injecting at high temperature and high pressure, combining, demoulding, finishing, coiling and packing. And the invention uses environment friend material, without toxicity and irritant odor. And it has long service life and can be recycled.
Description
Technical field
The present invention relates to a kind of doorway that is used for and remove shoe sole dust, foul, or be used for the preparation method that there is the ground cushion in water place in bathroom etc., be specifically related to a kind of preparation method of linear low density polyethylene lawn-shape ground cushion.
Background technology
In daily life, the plastic cement ground cushion material that generally uses is polyvinyl chloride (pvc).Information according to present grasp, polyvinyl chloride, it is a kind of polymer that is the vinyl chloride chemical substance, vinyl chloride itself is harmful to human body, let it be to the greatest extent, and polymer---polyvinyl chloride is harmless in principle, but the polymerization of any chemical substance is not completely, so the vinyl chloride of some does not have complete polymerization, but can't therefrom separate, these unpolymerized vinyl chloride are PVC material carcinogenic " chief culprits ".
Simultaneously,, generally can add plasticizer and improve pliability, can make the sort of thicker but also very soft simultaneously product because PVC itself also is harder.To the harm of human health also from the harmful chemical component of plasticizer.
If contact polrvinyl chloride product for a long time, the harmful substance in the material can have carcinogenesis to human body, particularly disturbs human endocrine, causes women's breast cancer, neonate's birth defect, male genetic obstacle even mental illness etc.Exactly because harm is serious, in packaging industry, Europe just banned use of PVC as packaging material before the several years.Japan has also stopped the PVC packing in 2000.Announce that according to council of World Packaging Organization the U.S., Japan, Singapore, Korea S and European various countries have now completely forbidden and used the PVC packaging material.And the commodity industry that comprises ground cushion also will be following closely, progressively substitutes and eliminate used pvc material.
In daily life, generally be lined with the surface has thread or the network structure ground cushion polyvinyl chloride of Shi Yonging, this kind structure ground cushion is general finer and closely woven, soft, scrape dirty weak effect, not wear-resisting, fragile, not anti-skidding, its ability of removing shoe sole dust and foul is relatively poor, and the Fouling Cleaning difficulty of accumulating; Hydrophobic effect is relatively poor, causes surface area water, and the people walks up very uncomfortable.
Summary of the invention
At the problem that existing ground cushion preparation method exists, the invention provides a kind of preparation method of linear low density polyethylene lawn-shape ground cushion.
This ground cushion adopts LLDPE (LLDPE) material.Be very safe a kind of chemical material, safety and long service life are the strong points of polythene material.The polyethylene odorless, nontoxic, the feel ceraceous has good resistance to low temperature (minimum serviceability temperature can reach-70～-100 ℃), and chemical stability is good, and the erosion of the most of soda acids of ability is insoluble to common solvent under the normal temperature, and water imbibition is little, and electrical insulation capability is good; And linear low density polyethylene (LLDPE); Mechanical performance between high density and low density polyethylene (LDPE) between the two; Fusing point is higher 15 ℃ than common low density polyethylene (LDPE); Resistance to low temperature is also good than low density polyethylene (LDPE); Environmental stress crack resistance is than high tens of times of common low density polyethylene (LDPE).
Adopting LLDPE (LLDPE) is raw material, adds industrial pigment, and addition is according to percentage by weight the line is busy 0.01%～2% of property low density polyethylene (LDPE) (LLDPE).
The processing technology step is as follows:
Raw material stirs, and raw material is added homogenizer respectively, mixes 1000～10000 rev/mins of stir speed (S.S.)s, time 5～150min.
The HTHP injection moulding.Mixed raw materials is added the HTHP injection machine, injection moulding under the condition of 170～190 ℃ of temperature, pressure 0.5～5MPa.
Injection molding.The material of injection moulding is added in the mould of casting according to shape of product, pass through mould shape.
Compound, at injection-molded product bottom surface bonding nonwoven and heat-resisting anti-skidding screen cloth.
Take off and touch, the above-mentioned steps injection-molded product is cooled to below 100 ℃, then with mold separation.
Arrangement is put modification in order to product appearance.
Last rolling, packing.
The product of the present invention preparation includes substrate, is covered with the careless thicket that is surrounded by vanelets on substrate, is convex-concave structure below the substrate.Described vanelets extends upward and its end is bending, and the quantity of vanelets is 6～10 in each careless thicket, and described subbasal male and female face is provided with skid resistant course.Substrate, careless thicket, vanelets constitute by the LLDPE that adds industrial pigment, and the scope of the whole height L of product is 12mm～18mm.
Simultaneously, on technology, we have adopted the method for integral molded plastic.In conjunction with the environmental protection properties of materials, and the moulding of employing lawn shape, beneficial effect is:
Owing to adopted internationally recognized environment-friendly materials, in daily use, have nontoxicly, have no irritating odor, human body there is not potential harm, pollution-free to surrounding environment, good environmental protection characteristics such as long service life and recyclable processing.
Owing to adopted unique technology outward appearance, have good anti-skidding, dedusting, scrape sand, hydrophobic effect; Simultaneously, be more convenient for removing the dirt of sole, and be seeped into the substrate bottom, ground cushion is tilted gently one to knock and promptly can make dust wander, keep pad face cleaning attractive in appearance, be easy to scrub, and feel is comfortable because the ground cushion surface is covered with the careless thicket that is surrounded by vanelets.
Owing to adopt emulational-mode (lawn shape), help improving people's visual enjoyment, beautify life.
