Abstract
An environment-friendly cutlery tray is made by raw materials in parts by weight as follows: 50-70 parts of husk powder, 10-30 parts of natural cellulose short fiber, 5-15 parts of an inorganic biological enhancer and 5-10 parts of a bonding agent. The preparation method of the environment-friendly cutlery tray comprises material preparation, mixing and drying as follows: husk powder and natural cellulose short fiber are uniformly mixed, the bonding agent is added and uniformly mixed, the mixture is granulated, and the granulated granule materials are dried. After weighing is performed according to the requirement of a mold pressing material, a high-frequency preheater is adopted for preheating the granule materials, and the preheated granule materials are put into a mold for mold forming. According to the environment-friendly cutlery tray, the main raw material adopts a natural material, waste of the main raw material can be biodegraded in the natural environment, and environmental protection is facilitated. The main raw material mainly comes from natural materials, the auxiliary materials are safe and non-toxic, and the made cutlery tray is safe and reliable. The preparation method is simple and convenient, and the preparation cost is low. The preparation method can be widely applicable to preparation of various cutleries, in particular to preparation of the cutlery tray.
Description
Technical field
The present invention relates to a kind of tableware tray and preparation method thereof, specifically a kind of environment protecting tableware pallet and preparation method thereof.
Background technology
Tableware tray be in dining room, meal hall, snack bar, the hotel instrument that contains food or the multiple Dining tool filling food are deposited for people.Only pallet need have been held to have held food, it can be people's food carrying and tableware easily.Pallet needs certain intensity and rigidity.Existing tableware tray mainly contains stainless steel pallet and plastic pallet.Stainless steel tableware pallet price is high, feel is ice-cold when using, and existing plastic tableware pallet is a kind of tableware tray be most widely used, but also exists and derive from petrochemical material, deficiency that price is higher.Particularly glass reinforced plastic tableware tray, it is glass fibre reinforced composion, carries out landfill disposal costly after recovery, and burning disposal can produce a large amount of residues, can not natural degradation, then carries out processing and very thorny, easily causes environmental pollution and the wasting of resources.Easily estrangement that is a kind of and natural, ecological is produced to the people of dining owing to have employed synthetic chemistry material produce tableware tray.
Summary of the invention
The object of the invention is to there is not easily natural degradation for solving current plastic pallet, easily causing the technical deficiency of environmental pollution and the wasting of resources, a kind of full biomaterial environment protecting tableware pallet and preparation method thereof is provided.
Technical scheme of the present invention: a kind of environment protecting tableware pallet, is made up of the raw material of following mass parts: shell powder 50-70, natural cellulose staple fibre 10-30, biologic inorganic toughener 5-15, tackiness agent 5-10.
Described shell powder is at least one in nutshell powder, walnut shell flour, tea fruit shell powder, coffee shell powder and cacao shell powder, and its granularity is 45-160 order.
Described natural cellulose staple fibre is at least one in wood, bamboo, fiber crops, cotton short fiber, and the length of staple fibre is less than 5mm.
Described biologic inorganic toughener is at least one in biological calcium carbonate, biological calcium phosphate and bio-silicon dioxide, and granularity is 800-1250 order.
Described tackiness agent is at least one in xylogen, tannin and Starch Adhesive.
The preparation method of environment protecting tableware pallet, is specially following steps:
(1) prepare burden, mix and drying: shell powder according to claim 1 and cellulosic short fiber are mixed, add tackiness agent and mix, granulation, the particulate material after granulation carries out drying treatment.Drying conditions 80-120 DEG C, time 0.5-2 hour;
(2) preheating and shaping: after requiring to weigh according to molding compound, adopt high frequency preheater to particulate material preheating, temperature 60-90 DEG C, time 2-5 minute, after preheating, particulate material puts into mould 180-200 DEG C of temperature, pressure is carry out compression molding under 20-50Mpa, and clamp time, at 3-5 minute, is environment protecting tableware pallet through deburring process after pallet product opens mould.
The present invention be adopt the shell powder made of natural nutshell, nut-shell, tea fruit shell, coffee shell and cacao shell the like waste and the natural cellulose staple fibre made with wood, bamboo, fiber crops, cotton for major ingredient, with biologic inorganic toughener and water-soluble binder be auxiliary material raw material sources in renewable resources, belong to environment protection health and to have dinner safely tool material.Various shell powder is the complex composite material of natural cellulose, hemicellulose and xylogen composition.Its abundant raw material source, cheap, materials'use safety and sanitation, during forming process, burn into does not does not wear and tear mould, and can have autoadhesion effect under high temperature, and most outstanding feature is low cost, can suitability for industrialized production application.Natural nutshell, nut-shell, tea fruit shell, coffee shell and cacao shell itself have tissue tight, quality is hard, wear-resisting, corrosion-resistant on-deformable feature, shell powder serves the effect of skeleton in the present invention, and cellulosic short fiber enhances the connection effect between shell powder.Unique proportioning that the shell powder made with natural nutshell, nut-shell, tea fruit shell, coffee shell and cacao shell and the staple fibre be made up of materials such as wood, bamboo, fiber crops, cottons are major ingredient and toughener and tackiness agent, the pallet of preparation is made to maintain the dense structure of shell own, quality is hard, smooth surface, wear-resisting, corrosion-resistant, not yielding and toughness is strong, impact resistant, the resistance to feature such as to beat, and possesses enough rigidity and intensity.Main raw material of the present invention derives from renewable resources, can save petroleum resource, reduces the dependence to petrochemical material.Solve glass reinforced plastic tableware tray to pass after glass fibre reinforced composion reclaims and carry out landfill disposal costly, burning disposal can produce a large amount of residues, can not natural degradation, then carries out processing and unusual stubborn problem.For this reason, adopt natural cellulose staple fibre to carry out the enhancing modified matrix material that is enhanced and can overcome the deficiency of glass-reinforced plastic material.Its main application characteristic is: (1) cellulosic fibre strength modulus is suitable with glass fibre; (2) cellulosic short fiber abundant raw material source, cheap; (3) its matrix material can carry out extruding, inject, the processing such as foaming, can recycling, residue can not be produced during burning; (4) Good Heat-resistance, under average operating, the strength of materials does not change; (5) during forming process, burn into does not does not wear and tear mould; (6) Mierocrystalline cellulose reinforced composite has water absorbing properties, but large change does not occur normal condition size.Add biologic inorganic calcium material more in addition, composition organic-inorganic composite reinforcing material, improves material over-all properties comprehensively.Main raw material of the present invention is all natural materials, and its waste can biological degradation in physical environment, is conducive to environment protection.Main raw material of the present invention derives from natural materials, subsidiary material safety non-toxic, and made tableware tray is safe and reliable.Preparation technology of the present invention, simple and convenient, cost of manufacture is low.The present invention can be widely used in various tableware tray, especially for the tableware tray of alternative glass-reinforced plastic material.
