Description

Manufacturing method of plastic floor tile substrate

The invention relates to a method for manufacturing a plastic floor tile substrate, in particular, it not only can effectively reduce the manufacturing cost, but also has extremely stable ingredients, and will not volatize and release toxic substances during use. The above hazards can have excellent safety in use, and those with more practical utility characteristics in their overall application.

According to the present, the layered structure of the existing plastic floor tiles is the bottom layer, the printed layer and the protective layer in order from bottom to top; wherein, the bottom layer is generally made of waste polyvinyl chloride [Polyvinylchloride, PVC for short] plastic material Manufacturing, after the waste PVC plastic material is crushed, added stone powder, and compression molding steps, the production of the substrate is completed. Since the entire life cycle of PVC is related to toxic substances, it is recognized by International Greenpeace The organization is called "toxic plastic". Polyvinyl chloride ranges from raw material chlorine and the intermediate product of the production process, EDC [dichloroethane], to VCM made from EDC [vinyl chloride, a monomer used to polymerize to form PVC] , Then the stabilizers [such as lead, cadmium] and plasticizers [phthalic esters, such as DEHP], and the hydrochloric acid generated after combustion and the century Dioxin is a serious threat to our environment and health.

The reason is that, in view of this, the inventors have maintained rich design and development and practical production experience in the related industries for many years, and then studied and improved the existing structures and deficiencies to provide a method for manufacturing plastic floor tiles substrates in order to achieve better practical value Purpose.

The main purpose of the present invention is to provide a method for manufacturing plastic floor tile substrates, which not only can effectively reduce the manufacturing cost, but also has extremely stable ingredients, and will not release toxic substances during the use process. Health hazards can have excellent safety in use, and those with more practical utility characteristics in their overall application.

The main purpose and effect of the manufacturing method of the plastic floor tile substrate of the present invention are achieved by the following specific technical means:

The main system includes the following steps:

A. Crushing: take the PVB [Polyvinyl Butyral Resin, polyvinyl butyral] film scrap used in the glued safety glass, and crush the PVB film scraps;

B. Add CPVC: Add CPVC [Chlorinated Polyvinyl Chloride, Chlorinated Polyvinyl Chloride] to the PVB film scrap after crushing;

C. Add calcium carbonate: add calcium carbonate again;

D. Forming: The crushed PVB film scraps, the CPVC, and the calcium carbonate are mixed, and then subjected to compression molding to complete the production of the plastic floor tile substrate.

A preferred embodiment of the manufacturing method of the plastic floor tile substrate of the present invention, wherein the crushed PVB film scraps, the CPVC, and the calcium carbonate are 10%~30%, 3%~15%, 55%~ by weight Mix at a rate of 87%.

In order to make the technical content, the purpose of the invention and the effect achieved by the invention more complete and clear disclosure, it is described in detail below, and please refer to the drawings and figures disclosed:

First of all, please refer to the first diagram of the manufacturing process diagram of the present invention. The present invention mainly includes the following steps:

A. Crushing: It is made of PVB [Polyvinyl Butyral Resin] used in glued safety glass. The PVB film is a commonly used support, which has strong binding force and high The optical clarity, easy adhesion to various surfaces, high toughness and high elasticity resin make it commonly used for gluing safety glass. During the process of gluing safety glass, many PVB film scraps will be produced. The PVB film scrap is a stable and non-toxic material, but its subsequent treatment is easy to cause environmental pollution problems, so that the PVB film scrap is used immediately, and the PVB film scrap is crushed;

B. Adding CPVC: CPVC [Chlorinated Polyvinyl Chloride] is formed from PVC [Polyvinyl Chloride, polyvinyl chloride] single polymer through chlorination. This CPVC has high temperature resistance, chemical inertness, inactivity, Excellent mechanical strength, non-conductivity, the safest combustion conductivity and smoke generation, etc., so that the CPVC added to the PVB film scrap after crushing can have high temperature resistance characteristics;

C. Add calcium carbonate: add calcium carbonate, which can increase the overall weight, and has the characteristics of wear resistance and high temperature resistance;

D. Forming: The crushed PVB film scraps, the CPVC and the calcium carbonate are mixed in the proportion of 10%~30%, 3%~15%, 55%~87% by weight, and then subjected to compression molding To complete the production of plastic floor tiles.

In this way, the finished plastic floor tile substrate can be formed into a printed layer and a protective layer in sequence at the upper end to produce a complete plastic floor tile for laying on the ground, because the plastic floor tile substrate is separately crushed Afterwards, the PVB film trim, CPVC, and calcium carbonate are mixed, and its ingredients are extremely stable, and will not release toxic substances during use. Relatively, it will not cause health hazards to users. Better use security.

Based on the above, the description of the use and implementation of the present invention shows that, compared with the prior art means, the present invention mainly has the following advantages:

1. In the present invention, the PVB [Polyvinyl Butyral Resin] used in glued safety glass is crushed, and then mixed with CPVC and calcium carbonate respectively, which can effectively reduce the production cost .

2. The present invention is made by mixing the PVB film scraps, CPVC and calcium carbonate after being crushed, so that its ingredients are extremely stable and will not release toxic substances during volatilization during use. Users have health hazards and can have excellent use safety, and those who have more practical functional characteristics in their overall application.

However, the foregoing embodiments or drawings do not limit the product structure or usage of the present invention. Any appropriate changes or modifications by those with ordinary knowledge in the technical field should be regarded as not departing from the patent scope of the present invention.

In summary, the embodiments of the present invention can indeed achieve the expected use effect, and the specific structure disclosed by it has not only not been seen in similar products, nor has it been disclosed before application, and has fully complied with the provisions of the Patent Law To meet the requirements, I filed an application for a patent for invention according to law, and pleaded for the review, and granted the patent.
