Description

A kind of manufacture method of plastic floor tile

Technical field

The present invention relates to a kind of manufacture method of plastic floor tile.

Technical background

At building decorating industry, PVC (polyvinyl chloride) plastic floor tile is convenient to construction because its light weight, pattern can be ever-changing and cost and price lower, so rather popular in American-European building materials market, also there is the production PVC of the man production firm of number plastic floor tile existing China's Mainland.Traditional PVC plastic cement stamp floor tile generally needs the mixing through PVC powder, plasticizer, filler and processing aid, opens operations such as refining and lamination coating, and the homogeneous floor tile then can obtain finished product as waxing directly through mill slice and necessary post processing after mixing.

Demand for the various performances of catering to the consumer, as need have the luminous noctilucence floor tile of energy at night in hotels and other places, with when having a power failure or unusual condition such as breaking out of fire guide the usefulness of direction when not having electric lighting, the dance hall then needs the radium-shine floor tile that can reflect laser light, to cooperate the irradiation of laser light, produce special lighting effects.The manufacture process of above-mentioned floor tile is identical with the manufacture process of aforementioned homogeneous floor tile, and adds the additive with specific function in mixed processes, as luminescent powder and fluorescent material etc.But because these additives are because price is very high, so on additional proportion, be difficult to grasp control: because of it is scattered in the PVC floor tile, most ofly hidden, cross as additional proportion and hang down that then effect is bad by PVC and filler, but as too much, then can cause irrational rising of cost.

In addition, for cooperating the needs of informatization epoch for the elimination and the prevention of static, the PVC producer also releases antistatic or the conduction floor tile.Recently the plastic cement conduction floor tile that occurs on the domestic and international market ties up to the conduction black smoke or the graphite of sneaking into larger proportion in the plastic cement component mostly and leads the purpose of releasing static as conductive agent to reach.But because such conductive agent color and luster is single, the conduction floor tile of gained also is difficult to change on impression, is difficult to satisfy the demand of existing interior decoration variation.

United States Patent (USP) 4,101 discloses a kind of conduction floor tile and manufacture method thereof No. 689, and so that above-mentioned shortcoming is improved, this product is led by insulating barrier and conductive layer and the static that runs through insulating barrier and released post and constitute.It is to produce insulating barrier earlier, on this insulating barrier, go out several and run through hole up and down, this hole is up-small and down-big, the paste resin that will contain conductive agent again has the conductive layer that becomes certain thickness than a side coated of big frustum diameter from the sheet semi-finished product, and the opposite side that makes pastel penetrate into taper hole forms static and leads and release post, make it plasticizing at a certain temperature, thereby utilizing the static penetrate insulating barrier to lead to release post reaches the floor tile bottom with surface charge, and utilizes the conductive layer of bottom that static is led to disengage.This kind manufacture method is more loaded down with trivial details and its resulting product outward appearance is more single, also can not effectively solve the diversified problem of impression.

Existing producer releases a kind of new-type conduction floor tile, and this conduction floor tile is to wrap up in attached conductive agent around the plastic cement particle, again with the particle compacting in flakes, thereby utilizes conductive agent to form conductive network, reaches and leads the purpose of releasing static.This kind product is because pattern is many and outward appearance is beautiful, and can be according to the actual requirements, changing its static leads and releases performance, so it is very popular on the market, as the conductive column (STATIC CONDUCTIVE) of Britain Mary company (MARLEY), the VIP of LG Corp of South Korea conduction floor tile series (LG VIP CONDUCTIVE TILE) etc.But the manufacturing process of these floor tiles is wrap up in attached conductive agent around the plastic cement particle after, accurate running roller calendering by special heater and automation control is handled, obtain finished product through operations such as the surface finish and the bottom mill ends again, the equipment precision of these processing procedure needs is very high, investment cost is very high, and control technology requires also very high.The floor tile dealer, especially medium and small dealer is difficult to even can't reaches.

Among the existing plastic floor tile dealer, the hot pressing Heat sealing machine is similar to vulcanizing press, is very general equipment, and its investment cost is not high, operates also simpler.For utilizing existing equipment and avoiding huge equipment investment, the dealer studies one after another and uses the hot pressing make-up machine to produce required function floor tile, as the method for noctilucence floor tile, conduction floor tile etc.The existing practice is wrapped up in attached additive by specific function for producing particles, utilizes the hot pressing Heat sealing machine to carry out the single slice hot pressing fusion, the semi-finished product of hot pressing fusion back gained is polished again and polishes, and obtains required floor tile.This kind production method also has significant disadvantages: at first, this kind producer genealogy of law monolithic production method is difficult to even stone, lacks material so very easily cause when producing, thus the finished product fraction defective of production and heavily the burning rate is high.In addition, when the plastic cement particle fused into the sheet semi-finished product, volume can be reduced into about original half, thus need matched molds can, this can cause stone inconvenience, and fusion effectiveness is extremely low.

Summary of the invention

The invention reside in the manufacture method that a kind of plastic floor tile is provided, utilize this method can reach the input cost of saving equipment, the purpose of enhancing productivity.

The manufacture method of plastic floor tile of the present invention comprises following operation: plastic cement particle production process, and promptly produce the plastic cement particle and wrap up in attached additive to obtain the required plastic cement particle of floor tile; Fusion process is by fusing the hot pressing of plastic cement particle to obtain fusing half product; It is characterized in that: to fuse half-finished thickness be more than 2 times of finished product thickness in resulting hot pressing in the fusion process, and hack operation through one, with the equipment that hacks these semi-finished product are cut into the finished product of some desired thicknesses, carry out post processing again, with end article.

Adopt method of the present invention, this floor tile is processed into multi-layer product through cutting equipment after plastic cement particle hot pressing fusion, enhance productivity thereby can reach, and reduces the purpose of equipment cost and production cost.
