Abstract

The essence of the technical solution lies in the fact that the composite contains from 58,5 to 88,5 weight % of polypropylene, from 10 to 40 weight % of natural fibres of cellulose (the length of the fibres from 0,2 to 2 mm) and from 1 to 1,5 weight % of silicon-based additive and from 0,1 to 0,5 weight % of additive based on dialkyl peroxides, which acts as a chemical catalyst. The obtained composite is supplied in the form of granules and is designed for a wide range of technologies for processing of plastics, for example injection.

Description

Composite with synthetic polymeric matrix and cellulose in the form of natural fibre fillers
Technology area
This technical solution regards the composition of the polymeric composite with natural fibre fillers on the basis of cellulose for the manufacture of plastic parts with higher utility properties.
Present condition of technology
Polymeric materials and their composites belong to the most progressively developing materials because the polymeric materials represent the most important segment of the production and consumption by volume between all technical materials and there is no doubt that they are crucial to modern technical society. The current development of polymeric materials and their processing technologies will continue in increasing volume and the success of individual materials developed by basic and applied research will be crucially influenced by the ratio between the price and the utility value of the material. This research area also includes the replacement of glass fibres by natural fibres which are from the environmental point of view the subject of interest of polymer processors. Application of natural fibres is a significant material change which traditionally aims not only for the automotive industry, but also to the areas of consumer industry, medical applications, etc. The advantage of natural fibres is, in comparison with other fibrous materials (used in the manufacture of composites), their low weight, low abrasion (preventing the wear of the processing machines), burning, nontoxicity, biodegradability, and in particular, the low price, independent of the price of oil.
Now the natural fibres are used in the industry as the reinforcement of shaped large- scale parts, e.g. wooden sawdust, containing cellulose fibres and nonwoven linen materials with the polypropylene. It should be emphasized that these are especially the products resulting from pressing, not from their injection, where they are subjects to high demands on quality, dimensional and shape precision of manufactured parts. The injection of synthetic composites with natural fillers is so far very few examined area with large possibilities and the potential for significant growth, and also this proposed technical solution is heading this area. Historically, the application of composites may be dated from the year 1908, when the composite material based on phenolic resin reinforced with wood flour was used for the first time (L. Baekeland). By the development of glass fibre of company Owens-Illincis Glass Co. (1933) the first fibreglasses were appearing, i.e. polymeric composites with glass fibres, e.g. coverings of aircraft radar (1942) or the parts of the bodywork of cars (1956, comp. Citroen), etc. In addition to glass fibre also the carbon, wood, ceramic fibres, etc. were applied for reinforcing purposes during the development of polymer composites. The hidden reality of today is the use of natural fibres for the production of polymeric composites used for the production of large-scale components of the internal padding and of the external parts of the bodywork of cars and other transport technologies. The share of bicomposites increases each year, but there is still few technical solutions and options. Especially the hemp, jute, flax, cotton, sisal, and wood are the most commonly used natural fibres. Known applications are components in a Mercedes C class, Daimler AG. (e.g. panels of the doors and acoustic insulation), the rear cover of bus engine, made from mat of natural fibres, etc.
The proposed technical solution responds to the growing demand and requirements relating to these materials, which are, however, in the Czech Republic, very little extended. Pressure on the applications of such materials is constantly growing, and not only as a result of the economic situation (the price of oil is still changing, but mainly grows), not only due to the possibilities of influencing of the final and utility characteristics of the products, but also in terms of climate change (almost unsolved recycling of existing parts of the synthetic plastics, synthetic plastics incineration, landfilling).
Principle of technical solution
This technical solution aims the creating of a composite with the targeted composition of the matrix, additive and filler on the basis of natural materials for the improvement of final and utility properties of the plastic parts with higher added value and environmentally much lower capacity, compared to the 100% synthetic products, i.e. with the environmental benefits. The essence of the technical solution lies in the fact that the composite contains from 58,5 to 88,5 weight % of polypropylene, from 10 to 40 weight % of natural fibres of cellulose (the length of the fibres from 0,2 to 2 mm) and from 1 to 1 ,5 weight % of silicon-based additive and from 0,1 to 0,5 weight % of additive based on dialkyl peroxides, which acts as a chemical catalyst. The obtained composite is supplied in the form of granules and is designed for a wide range of technologies for processing of plastics, for example injection. Examples of technical solution conduct
Polymeric composite with natural fibre fillers on the basis of the cellulose is described in the following examples, including an indication of the appropriate application, whereas the component A consists of polypropylene, component B of natural fibre cellulose (the length of the fibres from 0.2 to 2 mm), component C of additive based on silicon, component D of additive based on dialkyl peroxides.
