Abstract

The composite table top board has one main structure of cementing material, one decorating face layer, reinforcing ribs and one bottom frame structure of cementing material. Its making process includes the following steps: compounding the cementing material, spreading the cementing material inside mold with configured face layer, setting the reinforcing ribs, leveling the cementing material, forming in a molding press, setting the table top to the table, curing, eliminating mold and grinding. The present invention has the advantages of adopting inorganic cementing material producing no toxic and harmful gas, no product deformation, high production efficiency, low production cost, etc.

Description

A kind of composite top board and preparation method thereof

Technical field

The present invention relates to deck plate, the preparation method of the compound deck plate of the table that particularly lies fallow, kitchen coloured glaze platform.

Background technology

At present reach leisure table popular on the international market, baking oven, kitchen coloured glaze platform at home, its deck plate mostly uses a kind of compound panel and artificial stone plate.Its composition is backer board, unsaturated-resin and veneer material.Its recombination process is that the model that will need specification is seated on the workbench, by design veneer material is arranged in its scope, on the veneer material that sequences, pour into a mould unsaturated-resin again, after the slit of veneer material filled up, scrape one deck above the veneer material again and certain thickness resin is arranged when being gelling agent, then, treat to carry out sand milling, polishing again after whole composite platform solidifies again by last backer board.

The shortcoming of prior art has: 1, all process major parts of making the table panels are finished by hand, and not only efficient is low, quality also because of human factor can't be desirable keyholed back plate, cause qualification rate and cost uncontrollable; 2, employed unsaturated-resin can be emitted heat in the process of solidifying, and easily causes the warpage or the distortion of product, and secondly, unsaturated-resin can overflow pungent peculiar smell in process, harmful; 3, employed backer board use which kind of material all must by flat board more on demand specification cut and form, formed the waste of great manpower and material, increased the cost of product; 4, backer board adds resin and adds veneer material, has mutual exclusive problem to take place because of material is different, easily produces sequelae such as table facial ornament material and backer board come off, chap, peel off.

Summary of the invention

The object of the present invention is to provide a kind of composite top board,, use manpower and material resources sparingly, reduce production costs to improve the quality and the production efficiency of product.

For reaching above-mentioned purpose, the invention provides a kind of composite top board, with the agent structure of gelling material as deck plate, the surface has reinforcement, bottom to have " well " font or " rice " font convex tendon to cast with the gelling material in the middle part of the table top and forms coated with decoration plane material.

Described reinforcement is a reinforcement material with bamboo reinforcement or timber or burlap or flax silk or metal material or glass fibre or plastics.

A further object of the present invention is to provide a kind of preparation method of composite top board, this technical scheme is: batching stirs Binder Materials (with Portland cement and mixed type cement, or magnesia oxychloride cement), the Binder Materials of mixing is laid in the mould that sequences veneer material (can reserves the veneer material position in the mould or not reserve the veneer material position), place enhancement Layer again, wipe Binder Materials off, the mould of completing material is delivered to the last moulding of press, the table top that presses is sent to workbench together with pressing mold, shed the outer rim mould, finished product sent to carry out maintenance between maintenance and (decide on gelling material attribute, but steam curing, cure maintenance or natural curing), the demoulding again, sand milling is to finished product.

Advantage of the present invention is:

1, adopts inorganic coagulation material to replace the unsaturated resin of macromolecule, do not produce toxic and harmful in the production process, can not damage the workman; Inorganic coagulation material can just can not cause the product buckling deformation because of intense reaction generates heat at short notice yet in hardening process simultaneously;

2, replace original handwork with mould production, improved production efficiency, and quality also can obtain effective management and control;

3, one-shot forming technique has been cancelled original backer board, does not produce leftover pieces in the production, has saved the raw material and the amount of labour used, has reduced production cost greatly;

4, product is based on single inorganic material, and the surface is combined with inorganic veneer material, and the backer board of having given up original use is compound, has avoided because of the different drawbacks that produce with material of multilayer overlap joint, so can not produce problems such as interlayer crack or surface checking;

5, the back side of table face main body design has convex tendon, and distortion, warpage and the depression of table face are avoided in effectively weight reduction, have eliminated the common drawback of general table face.

The specific embodiment

The invention will be further described below in conjunction with structure chart and process chart.

A kind of composite top board of the present invention, with the agent structure of inorganic gel material as deck plate, the surface is coated with decoration plane material, and the table top middle part has reinforcement, bottom that " well " font convex tendon 1,3 or " rice " font convex

tendon

2,4 are arranged, and casts with the gelling material to form.

Technological process of the present invention is:

Embodiment 1

With the magnesia oxychloride cement is the die press technology for forming of main gel gel material.

(1) by weight percentage, prescription is as follows:

Light-magnesite powder 35～45%

Magnesium chloride solution 23Be ⁰40～50%

Talcum powder 2～3%

Calcite in powder 1.5～2%

Expanded perlite 8～10%

Additive 2.5～3.5%
