COMPOSIÇÃO DE PLÁSTICO HIDROSSOLÚVEL E PROCESSO  WATER SOLUBLE PLASTIC COMPOSITION AND PROCESS
DE OBTENÇÃO OBTAINING
CAMPO DA INVENÇÃO FIELD OF INVENTION
A presente invenção descreve uma composição de plástico hidrossolúvel e o respectivo processo de obtenção. Mais especificamente compreende uma formulação que não utiliza nenhum derivado de petróleo, dito plástico que reage ao fazer contato com qualquer meio líquido, retornando à forma liquida e hidrolisando com o corpo liquido receptor, sem alterar a propriedade física e química do líquido.  The present invention describes a water soluble plastic composition and the process for obtaining it. More specifically it comprises a formulation that does not use any petroleum derivatives, said plastic that reacts upon contact with any liquid medium, returning to liquid form and hydrolyzing with the receiving liquid body, without altering the physical and chemical property of the liquid.
ANTECEDENTES DA INVENÇÃO  BACKGROUND OF THE INVENTION
Os plásticos são materiais formados pela união de grandes cadeias moleculares chamadas polímeros, uma substância derivadado petróleo de alta massa molar, que consiste em moléculas caracterizadas pela repetição de um ou mais tipos de monômeros (ABNT, 2008).  Plastics are materials formed by the joining of large molecular chains called polymers, a high molecular weight petroleum derivative, consisting of molecules characterized by the repetition of one or more types of monomers (ABNT, 2008).
A fabricação de plásticos exige uma boa quantidade de água, produzindo resíduos e emissão de gases estufa, envolvendo ainda a utilização de substâncias químicas perigosas e gerando substâncias tóxicas durante a fabricação.  The manufacture of plastics requires a good amount of water, producing waste and greenhouse gas emissions, also involving the use of hazardous chemicals and generating toxic substances during manufacture.
No setor de embalagens, o uso intenso de plásticos gera grandes quantidades de resíduos que são descartados no meio ambiente. Atualmente, os resíduos plásticos representam cerca de 15 a20% do volume de resíduos nos lixões, levando em torno de 4 a 5 séculos para se degradarem. Devido à natureza não biodegradável da maioria dos plásticos, há uma grande preocupação dos ambientalistas com relação ao lixo produzido pelos mesmos, o qual contribui em grande parte pela poluição do meio ambiente. Nos EUA, 30% do volume total de lixo produzido diariamente é constituído de plásticos. Já na cidade de São Paulo, são produzidas 12.000ton./dia de lixo, dos quais cerca de 10% constituem-se de material plástico. In the packaging sector, the heavy use of plastics generates large amounts of waste that is disposed of in the environment. Currently, plastic waste represents about 15 to 20% of the volume of waste in dumps, taking about 4 to 5 centuries to degrade. Due to the non-biodegradable nature of most plastics, environmentalists are very concerned about the waste they produce, which contributes largely to environmental pollution. In the US, 30% of total volume The waste produced daily consists of plastics. In the city of São Paulo, 12,000ton./day of waste is produced, of which about 10% is made of plastic material.
Segundo Narayan [NARAYAN, R. Starch Basead Biodegradable Palstics& Products. In Third Inter. Symp. on Nat. Polym. Comp. (ISNAPOL) Proceedings, São Pedro - SP, Brazil, 2000, p.201-205.] as novas leis ambientais e a conscientização da sociedade moderna sobre a preservação do meio ambiente têm levado à pesquisa de novos produtos e processos que sejam ambientalmente compatíveis. Uma atual abordagem no desenvolvimento de novos materiais está atenta a todo o seu ciclo de vida, isto é, considera os impactos causados desde a matéria-prima empregada até o destino final do produto (descarte). Embora relativamente poucos produtos sejam concebidos considerando-se seu destino final (descarte ou reciclagem e descarte), os plásticos de descartabilidade rápida têm sido os produtos criticados com maior frequência sob este aspecto. Tais materiais apresentam impacto ambiental, na medida que embalagens de descartabilidade rápida assumem grande proporção do lixo urbano [SILVA, L.F. Ensaios para Avaliação da Biodegradabilidade de Plásticos. Anais do 4o Seminário das Comissões Técnicas da ABPOL, S P, 31/05 a 1/06 de 2000, p.10-12.]. According to Narayan [NARAYAN, R. Starch Basead Biodegradable Palstics & Products. In Third Inter. Symp. on Nat. Polym. Comp. (ISNAPOL) Proceedings, São Pedro - SP, Brazil, 2000, p.201-205.] The new environmental laws and the awareness of the modern society about the preservation of the environment have led to the research of new products and processes that are environmentally compatible. . A current approach in the development of new materials is attentive to their entire life cycle, that is, considers the impacts caused from the raw material used to the final destination of the product (disposal). Although relatively few products are designed with regard to their final destination (disposal or recycling and disposal), fast disposable plastics have been the most frequently criticized products in this regard. Such materials have an environmental impact, as fast disposable packages assume a large proportion of urban waste [SILVA, LF Plastic Biodegradability Assessment Tests]. 4 Seminar Proceedings of the Technical Committees of the ABPOL, SP, 31/05 to 1/06, 2000, p.10-12.].
No entanto, as exigências crescentes para a sustentabilidade e preservação do meio ambiente tornam os materiais biodegradáveis um fator competitivo para muitos setores ligados ou dependentes desses materiais.  However, increasing demands for sustainability and environmental preservation make biodegradable materials a competitive factor for many industries linked to or dependent on these materials.
As pesquisas apontam na substituição dos plásticos convencionais por plásticos biodegradáveis, que constituem uma família de plásticos que se degradam sob a ação de organismos vivos e também por meio de reações abióticas, tais como fotodegradação, oxidação e hidrólise, que podem alterar o plástico devido a fatores ambientais (RAGHAVAN, D. Polym. Plast. Technol. Eng. 41 1995.0 E (A ASS, W., AMASS, A., TIGHE, B. Polymer International 47, p.89- 144 (1998). Research points to replacing conventional plastics with biodegradable plastics, which are a family of plastics that degrade under the action of living organisms. and also through abiotic reactions such as photodegradation, oxidation and hydrolysis, which may alter plastic due to environmental factors (RAGHAVAN, D. Polym. Plast. Technol. Eng. 41 1995.0 E (A ASS, W., AMASS, A., TIGHE, B. Polymer International 47, p.89-144 (1998).
O plástico biodegradável requer condições específicas para poder degradar-se corretamente e, se não houver um grande cuidado em manejá-lo, pode tornar-se para o ambiente pior do que o plástico convencional. Estes plásticos, se degradados por microorganismos anaeróbicos, gera metano, um gás 23 vezes mais potente como efeito estufa, além de ser explosivo.  Biodegradable plastic requires specific conditions to be able to degrade properly and, if not handled with care, can become worse for the environment than conventional plastic. These plastics, if degraded by anaerobic microorganisms, generate methane, a 23 times more potent greenhouse gas, in addition to being explosive.
Mais recentemente, o estado da técnica descreve plásticos hidrossolúveis que são completamente solúveis em água, não deixam resíduos e são inofensivos à saúde.  More recently, prior art describes water soluble plastics that are completely water soluble, leave no residue and are harmless to health.
No entanto, estes plásticos hidrossolúveis utilizam matéria-prima originada do petróleo, mesmo aqueles que fazem uso de cargas vegetais ou similares.  However, these water-soluble plastics use petroleum-based raw materials, even those that make use of vegetable fillers or the like.
Dessa forma, é objeto da presente invenção uma composição de plástico hidrossolúvel que não utiliza nenhum componente derivado do petróleo, cumprindo a sua função de ser efetivamente ecológico, dito plástico hidrossolúvel que reage em contato com um meio líquido, voltando à forma líquida e hidrolisando com o corpo líquido receptor. O plástico hidrossolúvel compreende uma carga de amido, um catalisador e sílica com uma base de água, formando um gel que é espalmado em um substrato celulósico e submetido a aquecimento de forma a gerar uma película plástica que em contato com um líquido dilui rapidamente e hidrolisa, sem alterar a propriedade física e química do líquido. DESCRIÇÃO DETALHADA DA INVENÇÃO Thus, the object of the present invention is a water-soluble plastic composition that does not use any petroleum-derived component, fulfilling its function of being effectively ecological, said water-soluble plastic that reacts in contact with a liquid medium, returning to liquid form and hydrolyzing with water. the receiving liquid body. Water-soluble plastic comprises a starch, catalyst and silica filler with a water base, forming a gel that is flattened on a cellulosic substrate and subjected to heating to generate a plastic film which upon contact with a liquid rapidly dilutes and hydrolyzes. without changing the physical and chemical property of the liquid.
