    专利说明:

     On the island of La Palma, they appear for the first time in the island capital, Santa Cruz de La Palma, also known as Villa del Apuron in the Sinodales Constitutions of Vázquez de Arce in 1515. 5 With techniques derived from paper as raw material they are performed the popular "dwarfs of the Island of the Palm" as well as masks that represent giants, big heads and other traditional figures of towns and peninsular cities, that satirize popular personages of the time, with the intention of distracting and making people laugh. 10 As for paper-derived applications, those based on cellulosic materials are known, such as paper, cardboard, cardboard, cardboard-stone, paper agglomerates and the like based on cellulose, in which different uses are claimed, for example , funeral urmas, or for the use of 15 different modular supports, at the height of children, representing characters, animals, objects (trees, fountains, aquariums, carousel ...) or any other form. Many plastic materials have characteristics that involve conflict with very important aspects and values in terms of handling, strength and durability, especially when we want to use them as an intermediate step towards works in materials of high strength and durability such as bronzes. So far the paper mache has not been considered as final material 25 for works of art of great importance or of great artistic value. Traditionally, different "formulas" are cited for the production of paper mache. The present invention has the advantages over paper mache and other traditional materials obtained from paper fiber and binders: a) .- Very superior mechanical strength; b) .- lightness; and c) .- plasticity suitable for modeling for artistic purposes. a) Mechanical resistance. -The components used, together with the appropriate formulation thereof; the process of making the mixture; and the setting process of the resulting material, allow to obtain clearly superior mechanical resistance results, which can exceed the values of the known "paper mache" by more than 300%. Once they reach the setting point we are faced with a material with characteristics of durability and resistance that make it suitable as the final material in the realization of works of art. b) The aforementioned strength allows to obtain emptyings and pieces of small thickness and therefore very light in comparison with the other materials known at present. c) Plasticity has been one of the objectives that were pursued from the first moment in the search for a new material so that it wasDESCRIPTION OF THE INVENTION This is a modeling paste composed of paper fiber, liquid binder, cementitious powder, water, modeling, non-toxic and easy to handle. The cementitious powder (in solution) fills the interstices or pores left by the mixture of cellulose and glue, resulting in a complex material that allows both its molding for industrial application (according to the proportions 10 between the indicated margins); or a plastic material, optimal for artistic expression in applications of fine arts, crafts and DIY. The treatment of the paper fiber is based on a process of hydration with water followed by the elimination of the excess water, as well as a certain process of beating and mixing it with the liquid binder and the cementing powder. This paste can be worked at room temperature and there is a time range between 2 minutes and 2 hours, before drying and hardening. In addition, setting (process characterized by drying and hardening of material) does not require applying any type of product, although it is always possible to modify its initial properties through accelerators or retarders. 25 Nor does it require the use of toxic substances as solvents; emulsifiers, preservatives, or gas or liquid catalyst products that require special handling. It therefore has safety features or low toxicity, depending on the liquid adhesive used, so it can be handled indoors and does not require special ventilation. Both in its possible molding and demoulding, it does not require special products or solvents, being able to use basic materials such as soap or petroleum jelly, and even a film-like material to prevent it from adhering to the mold. As an additional advantage, it can be manipulated (manually shaped) to give applications or expressions of an artistic type or related to the 40 fine arts or crafts. The material is capable of admitting different types of supplements that improve the specific properties sought. In the case of looking for a greater resistance of mechanical type, it can be provided with different types of reinforcements, whether they are metallic in the form of a mesh or metallic filaments; as of flexible materials of polymeric mesh type, or even fiberglass, among many others.New layers of the same product can be applied to the material by accumulation (among which some new material such as sheet; mesh; etc) can be introduced resulting in complex sandwich-type materials with superior elastic or resistant properties. You can also apply 5 new materials or layers, although the first layer is already hardened, which facilitates the formation by molding of complex parts. In order to obtain comparable results, numerous tests have been carried out on parts obtained with dimensional homogeneity, carried out by means of a duralumin mold (Figure 1). After their subsequent drying and setting process, they were subjected to compression resistance tests, and through the study of their stress-strain behavior, in order to measure and compare their mechanical characteristics. 15 The pieces of the material object of this patent, in the form of a spherical shell 3 mm thick (Figure 1, C), in comparison with the patterns of identical size obtained from the traditional mixtures of glue and cellulose fiber that make up the paper Mache, have resulted in a resistance that, on average, exceeds 300%. 20 In Figure 2 we can see how the piece resists up to 330 kp with a small deformation, around 4 mm. in the form of crushing its dome. After the initial crushing, the piece becomes resistant again until around 450 kp. pressure undergoes a new deformation. From 25 of this moment the deformation rises from 6 mm to 8 mm with only a progressive increase of 50 kp. Finally, it resumes load until the moment of breakage that occurs after resisting 525 kp with 8.88 mm deformation. PREFERRED EMBODIMENT OF THE INVENTION Plastic compound made from the following composition: 38% (by weight) of cellulose, 38% (by weight) of vinyl glue, 14% (by weight) of cementitious powder, and 10% ( by weight) of water. The treatment of cellulose 35 is based on a process of hydration with water, as well as a certain process of beating and mixing it with the vinyl glue and the cementitious powder. 40 45
