The manufacturing method for the environmentally-friendly tea tray molded by single-pressing uses the bits of wood as raw materials, adopts the single-pressing molding method for manufacturing the tea tray, has simple method, saves cost and is in line with environmental protection.
Description
Technical field
The present invention relates to the manufacture craft of tea tray, a kind of specifically preparation method of environmental protection tea tray of a compression moulding.
Background technology
The material of existing making tea tray has iron, wood, pottery etc., and is maximum with wooden tea tray, but existing wooden tea tray is to make of former woods, also very big to planting wooden consumption, wastage, and the general age that requires to plant wood is very high, cost height not only, and do not meet the environmental protection needs.
Summary of the invention
At the defective that exists in the prior art, the object of the present invention is to provide a kind of preparation method of environmental protection tea tray of a compression moulding, with the wood chip raw material, adopt the method for a compression moulding to make tea tray, method is simple, saves cost, and meets the environmental protection needs.
For reaching above purpose, the technical scheme that the present invention takes is:
A kind of preparation method of environmental protection tea tray of a compression moulding is characterized in that: its concrete steps are:
Step 1: broken wood chip: wood chip is crushed to grain of rice shape with disintegrating machine;
Step 2: raw material is mixed system: pour the wood chip of grain of rice shape into mixer, the wood chip that is stirred to grain of rice shape is soft and even; In mixer, add glue according to 14: 5 weight ratio again, be stirred to evenly, obtain containing the wood raw material of glue;
Step 3: pour mould into: the wood raw material that will contain glue is poured in the tea tray particular manufacturing craft, and said tea tray particular manufacturing craft is the metal die of one-shot forming structure;
Step 4: be pressed into big: tea tray particular manufacturing craft and the wood raw material that contains glue are heated to 150～180 ℃, the tea tray particular manufacturing craft is applied the pressure that is not less than 15 tons, suppress after at least 45 minutes, opening the tea tray particular manufacturing craft, to obtain tea tray big;
Step 5: coat protective layer: after the big polishing of tea tray removed big limit, coat the priming paint that at least one layer thickness is 1.3～1.5mm, the surface roughness Ra value big up to the tea tray that is coated with priming reaches 1.0～1.5um; By the time after priming paint is done, spray one deck with spraying paint with spray gun and coat with lacquer outward, the tea tray that can obtain making through natural mummification in 2～4 hours.
Outer lacquer can be wood grain striped color or other pattern decoratives.
On the basis of technique scheme, said wood chip is one or more the mixture in saw chaff, timber leftover pieces, the wood waste; Said glue is one or more the mixture in free formaldehyde, the benzene,toluene,xylene.
The preparation method of the environmental protection tea tray of a compression moulding of the present invention is a raw material with the wood chip, adopts the method for a compression moulding to make tea tray, and method is simple, saves cost, and meets the environmental protection needs.
The specific embodiment
The invention discloses a kind of preparation method of environmental protection tea tray of a compression moulding, its concrete steps are:
Step 1: broken wood chip: wood chip is crushed to grain of rice shape with disintegrating machine;
Step 2: raw material is mixed system: pour the wood chip of grain of rice shape into mixer, the wood chip that is stirred to grain of rice shape is soft and even; In mixer, add glue according to 14: 5 weight ratio again, be stirred to evenly, obtain containing the wood raw material of glue;
Step 3: pour mould into: the wood raw material that will contain glue is poured in the tea tray particular manufacturing craft, and said tea tray particular manufacturing craft is the metal die of one-shot forming structure;
Step 4: be pressed into big: tea tray particular manufacturing craft and the wood raw material that contains glue are heated to 150～180 ℃, the tea tray particular manufacturing craft is applied the pressure that is not less than 15 tons, suppress after at least 45 minutes, opening the tea tray particular manufacturing craft, to obtain tea tray big;
Step 5: coat protective layer: after the big polishing of tea tray removed big limit, coat the priming paint that at least one layer thickness is 1.3～1.5mm, the surface roughness Ra value big up to the tea tray that is coated with priming reaches 1.0～1.5um; By the time after priming paint is done, spray one deck with spraying paint with spray gun and coat with lacquer outward, the tea tray that can obtain making through natural mummification in 2～4 hours.
Outer lacquer can be wood grain striped color or other pattern decoratives.
On the basis of technique scheme, said wood chip is one or more the mixture in saw chaff, timber leftover pieces, the wood waste; Said glue is one or more the mixture in free formaldehyde, the benzene,toluene,xylene.
Below further specify the preparation method of the environmental protection tea tray of a compression moulding disclosed by the invention by a specific embodiment:
With the tea tray for preparing one 0.0115 cube, weigh 0.25 square of 8 kilogram, area is example, needs 14 jin wood chip, 5 jin glue;
Step 1: broken wood chip: 14 jin wood chips are crushed to grain of rice shape with disintegrating machine;
Step 2: raw material is mixed system: pour the wood chip of grain of rice shape into mixer, the wood chip that is stirred to grain of rice shape is soft and even; In mixer, add 5 jin glue again, be stirred to evenly, obtain containing the wood raw material of glue;
Step 3: pour mould into: the wood raw material that will contain glue is poured in the tea tray particular manufacturing craft, and said tea tray particular manufacturing craft is the metal die of one-shot forming structure; The structure of tea tray particular manufacturing craft is general iron mould, and mould is the one-shot forming structure, and shape changes customization as required, and mould can adopt existing techniques in realizing;
