Abstract
The invention relates to a green substrate made by plant fiber and binder, wherein the plant fiber is selected from straw, sunflower, maize stalk, rice hull, reed, branch and so on, and the binder isfrom corn starch or the mixture of melocol moulding powder, chalk clay, gelatin, polyolefin and corn starch. The said raw material is intimate mixed to put into moulding machine, and then is stamped on demand at high temperature and hiagh pressure, after grinded by edge trimmer and sterilized by UV according to conventional method, the product is made finally.
Description
Technical field
The present invention relates to a kind of environmental protection substrate, relate to a kind of production method of the environmental protection substrate made from vegetable fiber specifically.
Background technology
The development of the industrial revolution has promoted human civilization advance, but has also brought some negative effects simultaneously.The production of building board widely applies formaldehyde as bonding agent, causes very big harm to human beings'health; The application of plastic products has also caused a large amount of pollutions when bringing convenience for human life.People recognize the using value of environment-friendly products, develop pulp product, but because the technology of producing cause very serious pollution, and excessive exploitation and felling has caused environment damage.People begin one's study and utilize availability is not high in the daily life wheat straw, peanut shell, cotton stalk, straw, weeds etc. to make the material of environmental protection.
Introduced prescription and the technology of making natural plant dinnerware with sawdust, wood shavings, wheat straw, straw, rice hulls etc. among Chinese patent ZL96118613.5 " natural plants disposable tableware and production technology thereof " and the Chinese patent ZL02133745.4 " utilizing quick shaping agent to produce the technology of dining set made of plant fibres ".But its prescription, complex process, and the disposable tableware performance of introducing among the Chinese patent ZL96118613.5 is good inadequately, and cause the huge waste of resource easily.
Introduced among the Chinese patent ZL01802966.3 " a kind of method of utilizing natural material to make plastic-substitute " and utilized rice husk and glue to make the method for plastic-substitute, but widely applied formaldehyde in this technology, bigger to environment and human health damage.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, provides a kind of Recipe simple, with low cost, the production method of the environmental protection substrate made from vegetable fiber that range of application is wide, and this product can be widely used in each field of living.
Environmental protection substrate of the present invention is that raw material and proportioning make by following material:
Vegetable fiber: the mass percent of binder is for being 70%-90%: 10%-30%.
Vegetable fiber can be straw powder or sunflower bar, cornstalk, cottonly do, in the powder of rice husk, wheat straw, branch etc. any or appoint several mixtures; Binder can be that corn starch also can be the mixture that is mixed for 20-35%: 6-20%: 12-16%: 6-12%: 40-55% by mass percentage by urea-formaldehyde moulding powder, chalky soil, gelatin, polyolefin, corn starch.
The method of producing product of the present invention is as follows:
Choose the vegetable fiber of said ratio, cross the 100-200 mesh sieve, the binder that adds said ratio, stir, put into forming machine punch forming on demand under 170-200 ℃ of high temperature 170-500 ton condition of high voltage, polish through trimmer, more according to a conventional method behind disinfection by ultraviolet light, i.e. cost product.
Utilize production tableware handicraft commodity of the present invention also can be used as cabinet housing or life structural lumber.
The environmental protection substrate of being produced when adhesive is chosen as corn starch in the prescription is selected materials and is natural materials; do not contain harmful chemical composition; main being suitable for produced tableware handicraft commodity; the environmental protection substrate intensity of being produced when binder is mixture is big; density is little; resistance to compression is anti-falls, and main being suitable for produced cabinet housing or life structural lumber.
Prescription of the present invention, technology are simple, can not cause environmental pollution; The raw material scope of selecting material is wide, and is with low cost; Product strength is big, and crushing resistance is good, and is not easily broken, and degradability is good and the fragrance of a kind of plant of light nature arranged.
