PROCEDURE FOR STATIC REINFORCEMENT OF BATH-TUB COMBINED BY USING POLYURETHAN AND LAMELLAR MATERIAL
Technical domain:
The procedure falls under the domain of sanitary and latrine equipment made of plastic material. Technical problem:
The technical problem which is solved by this invention consists of solving the problem of static reinforcement of the bath-tub, made up of plastic mass without the usage of material such as polyester resin, glass fiber, dissolvent which are evaporable and highly toxic, as other materials which are used as a filler.
By this invention a problem is solved by gaining a product of high quality material combinations which solve the problem of static reinforcement, at that a request has been fulfilled in regard to ecology, in regard that by a simple procedure of separation different materials are separated, after which they are recycled and used again in the process of the production.
Technical condition:
Because of the problem of strength and compactness in production of acrylic bath-tubs, there is a necessity for additional static reinforcement. Known, ordinary and the most common procedure in the production of acrylic bath-tubs is using polyester resin and glass fiber. The reinforcement of vacuumed or injected shell of the bath-tub is done mainly by inflicting a layer of polyester resin and glass fibers with fillers, by using certain chemical components which come in sight of an accelerant dissolvent which is used for the acceleration of chemical reactions, by using expensive equipment for the application of polyester resin. This is by now the most common technical condition and implies many other disadvantages.
Some of the crucial disadvantages are:
Length of the production process
Using different other materials
Usage of polyester resin and glass fiber, which are mainly imported and very expensive materials,
Usage of glass fibers in the production process, on occasion of installment and product, increases the risk from mechanical violation.
Extremely expensive equipment for the application of polyester resin,
Combination of stated materials forbids recycling, which is common with plastic materials, that after recycling it can be again used in the product process,
Ecologically unaccepted product procedure because of the emission of toxic and flammable substance.
In the technical condition- Vacuumed or injected sub shell for the static reinforcement of bathtubs, by the patent application P-0968/05 Bogoljub Bozic, in great measure solves the state disadvantages, ecologically accepted product process in regard to the under shell which is made up of the same or similar material, solution with implanted stem after which the mask appears, where there is no need for building or tile fitting. But, for the under shell a mold must be made for each bath-tub. By the invention which is under protection, a problem is solved in cases when there is a classical approach of installing built in bath-tubs without making the under shell from
the same or similar material, but solving the previously stated disadvantages stated in the technical condition.
The authors have essentially changed and introduced a new procedure in the production of bathtubs from plastic mass and received the final product which is ecologically acceptable and of exceeding quality.
Presentment of essential invention:
The invention does not refer to a totally new procedure in the production of bath-tubs, as well as the static reinforcement, in which a product of high quality is gained, and by that no other additional equipment be used, nor is the product cycle extended. On the existing acrylic shell of the bath-tub a polyurethane layer is infringed with a sputtering, and under the shell of the bath-tub in the polyurethane layer a lamellar material is inserted. With this combination and arrangement of the stated materials not only in the static reinforcement but also better insulation is obtained. The esthetical color problem is solved by inflicting the color-coating.
The invention enables a more efficient and faster production that is increasing productivity. - Very high quality in regards to the static reinforcement of acrylic bath-tubs,
Simple and fast binding of polyurethane layer with lamellar material of the bath-tub shell,
Total elimination in the usage of polyester resin, glass fibers and fillers which are proven to be a health hazard for human usage,
Ecologically accepted and comfortable production process in all phases, taking into account the final installment of the product,
Does not considerably increase the cost in the production, taking into regard that polyurethane as an expensive material considerably reduces inserted cheaper lamellar material.
Considerably increases the insulation, which enables longer maintenance of the required water temperature.
The derived final product of considerably less weight in regard to the existing one, conduces the total static ballast on a building object.
Ecologically accepted when recycling matters, that is with the simple procedure of separation the materials can be separated and recycled and again used for the production of the same or similar products.
It can (large) be mass produced,
It fulfills high standards of the product which are dedicated for human use.

Detailed description of the invention
By observing Picture 1 and Picture 2 the procedure can be clearly seen, the appearance and allocation of the material which are added on the acrylic shell because of its stability and static reinforcement.
On the acrylic shell 1 gained by classical procedure, a polyurethane layer is infringed 2 as a binding material between acrylic shell 1 and lamellar material 3. The polyurethane layer accept that is has a binding role; also has the role of a excellent thermal insulation. It is gained by inflicting method of syringing or injecting (injecting under the closed mold). One or multi component polyurethane is used primarily because of better occlusion of the bath-tub shell 1 and polyurethane layer 2. For syringing a recognized appliance is used specifically and adjusted for syringing different kinds of polyurethane in contingent upon which will be used.
The polyurethane layer 2 is infringed before and after inserting the shell material 3 which is placed on critical parts of the shell 1 that is under the parts where the same tolerates the highest pressure /base of shell 1 and the upper shell rest 1/. The fullness of the polyurethane layer 2 depends on the surface and shape of the shell 1 and from the type of polyurethane which will be used, and will be as such to satisfy the conventional standards / when assessing the fullness of the polyurethane layer characteristics of the material as well as the surface and shape of the bath-tub shell will be used 1/.
The lamellar material 3 is added for extra stiffening and static reinforcement of the bath-tub shell 1 there where the polyurethane layer 2 is not sufficient enough, and withal replaces and sufficiently reduces the quantity of the expensive polyurethane material. The shell material 3 can be of extra ducted plastic mass such as: ABS, PMMA, PS or from other molded materials and composites.
For the shell material 3 always a material which enables the possibility of recycled final product is used, as well as the possibility that it can be recycled by itself. In regard to that the bottom tolerates higher static reinforcement; the shell material 3 is placed exactly on that part, as also on the upper shell rest 1 because it is parallel and follows the shape of the bath-tub shell 1 under which it is placed. The fullness of the shell material 3 in accordance of the type and compactness of the material, which will be used as well as the dimension and shape of the bath-tub shell 1. The final coating 4 is infringed on a already formed polyurethane layer 2 by syringing or lubrication, and always in the desired color as to cover the specific color of the polyurethane layer 2. Enables and fulfills the esthetic moment.
For the final coating 4 colors in dissolvent's which do not have a hazard impact on human health are used, ecologically accepted and also do not have an impact on the possibility of recycling of the final product. The dissolvent is deactivated such as toluene, styrene... which has a high emission of destructive material. It is best to use colors on the bases of polyurethane acetate dissolvent's.
