Abstract
The invention discloses rich mineral paper tableware, and a production method thereof. The rich mineral paper tableware comprises calcium carbonate, polyethylene, polypropylene, an anti-oxidant, a resin, ACR adhesive, a composite stabilizing modifier, and wood fiber powder. The production method comprises following steps: (1) the raw materials are delivered into a mixer for high speed mixing at a certain ratio; (2) modification is carried out, wherein a mixture obtained via high speed mixing is subjected to full dispersing and kneading so as to obtain a strip material or a plate material; (3) pelleting is carried out, wherein a pelletizer is used for preparing material particles from the obtained strip material or the plate material, so that it is convenient for transporting, raw materials can be provided for a plurality of parallel production lines, and production efficiency is increased; and (4) production is carried out, wherein the material particles are subjected to extrusion and blow moulding so as to obtain needed products.
Description
Technical field
The present invention relates to a kind of environment protecting tableware, be specially stone paper tableware and preparation method thereof.
Background technology
Ecotope is the primary condition of human survival and development, is the basis of socio-economic development.The protection and harnessing of ecotope, is not only the significant problem paid close attention in the world, and be related to 21st century China's economy and society Sustainable development.Forest is the skylight of ecotope, the Green Ark of the mankind, the cradle of civilization, research and practice shows, forest maintains future and the destiny of the mankind, as the theme of land ecology, forest is the key solving global ecological environment crisis, it can improve air quality, available protecting diversity of organism, prevent erosion, check desertification, prevent Soil degradation, alleviate the crisis of water resources, eliminate or alleviate noise pollution ... forest is the tie of relationship environment and sustainable economic development, it provides physical environment basis for Sustainable development, it is the main body of bioenergy.
United nations environment form claims: forest is as the most original maximum on the earth ecosystem, its area urgency of 30 years is in the past according to minimizing, only in the 90's of last century, Global Forests area just decreases 9,400 ten thousand hectares, account for 2.4% of the forest total area, indiscriminate felling of trees, overfarming makes the arable land serious degradation in the world 23%, the land area in the whole world more than 1/3 faces the prestige association of Desertification, and the water supply in the whole world has also lighted red light.
Data shows, the annual wood of China just total amount consumed reaches 1.7 billion cubic meters, and domestic 1.2 billion cubic meters that only can provide, imbalance between supply and demand is very outstanding, after it is predicted 3 years, China's timber supply and demand breach will reach 6000-7000 ten thousand stere, will reach 1.4-1.5 billion cubic meter to this numeral in 2015.
Statistics shows: the annual production and application of China reaches 60,000,000,000 pairs in the disposable wood sanitary chopsticks of catering trade, needs to blow to cut down 2,500 ten thousand large trees grown up 15 years, reduces area of woods 200 ten thousand stere.The disposable lunch-box that China uses every year is more than 12,000,000,000, the disposal plastic cup consumed and dixie cup reach more than 50,000,000,000, these Dining tool products are being provided convenience for people efficiently simultaneously, also many potential risks are brought, a large amount of consumption and the waste forest reserves, the green ecological environment that havoc people depend on for existence.They not easily reclaim, and be 200-400 at the degradation cycle of occurring in nature, if be buried in soil and the saturating acidity greatly affecting soil is hindered crop growth, eaten the lighter's Digestive tract by livestock by mistake and obtain seriously ill then dead, if burn, discharge a large amount of harmful poisonous gas.Owing to using these wastes that accumulate over a long period to cause the ecological environmental pollution be on the rise in a large number, having become global public hazards, to be named as white pollution be the invention suffering cake most, annoying China and the world.
How to control and eliminate this white pollution spread the Social Events that development has become the world today.For this reason many countries and regions start for a long time nontoxic can the development of degradable or renewable resource tableware material, successively have developed can be degradable the disposable dinner ware made by vegetable materials such as starch and grain shell, straw, bagasses or take starch as the polypropylene biological degradable tableware of main component, light, bio-degradable tableware and paper table ware are multiple, wherein simple, the large low price of output of the two degradative tableware indices good process of polystyrene, but it is undesirable to lack recovery value degradation effect.
Light, bio-degradable tableware in acrylic material, add the starch of more than 50% and the photo-thermal electricity of 10% urges depressant prescription, chemical reaction does not occur for starch in this degradable dinner set taking starch as major ingredient and auxiliary agent and poly-hydrocarbons changes, and therefore, the character of its plastics do not change.Only be to make its fragmentation by the effect of starch with the difference of common porous plastics mess-tin, fundamentally do not solve the character of plastic foam.Paper table ware can carry out renewable resources, easily degrade back to nature due to the value itself with recycling, and in degradation process without any hazardous and noxious substances remain in large spontaneous combustion be on our times generally acknowledge [Green Packaging] but its raw material is wood pulp and straw pulp, straw pulp is produced the problem of environmental pollution compatriots caused and is all known, wood pulp consumes the ecotope that above-mentioned forest resourceies destruction people Men Lai has survived in a large number, in addition the scarcity of resource is that it can not sustainable development, is faced with the double contradition of eco-environmental conditions.
