Abstract

The invention discloses a kind of formaldehyde-free density boards and preparation method thereof, the formaldehyde-free density boards are for raw material, using soybean protein glue as adhesive with the cornstalk of recovery, rice straw, wheat straw one or more therein.Its preparation method is：Raw material preparation, the preparation of glue, mixing, precompressed, bake pressure and drying.Not only more health environment-friendly, and with the characteristics of intensity is high, humidity resistance is good of the invention.

Description

Formaldehyde-free density boards and preparation method thereof
Technical field
The present invention relates to a kind of density board, specifically a kind of formaldehyde-free density boards and preparation method thereof.
Background technology
With rapid economic development, living standards of the people are stepped up, and people are also more next to the quality requirements of timber floor It is higher.The laminated flooring manufactured using density board can meet expectation of the people to floor price, but most of at present strong Change floor in quality and solid wooden floor board still has larger gap, it is unpleasant, strong that consolidated floor has content of formaldehyde height, temperature The low, moisture resistance of degree is poor, easy moisture expantion shortcoming.
The content of the invention
The purpose of the present invention is to overcome the deficiencies of prior art and provide a kind of formaldehyde-free density boards of health environment-friendly and its making side Method.
To achieve the above object, the technical solution adopted in the present invention is：Formaldehyde-free density boards and preparation method thereof, the nothing Aldehyde density board is for raw material, using soybean protein glue to be gluing with the cornstalk of recovery, rice straw, wheat straw one or more therein Agent, wherein every cube of formaldehyde-free density boards include the soybean protein glue of double centner.
The present invention preparation method be：
（1）It is prepared by raw material：Selected straw is cut off, boiling 1-2 hours at 150 DEG C, steamed straw adds water powder The particle for being less than 3mm for particle diameter is broken into, then is dried, makes its moisture control in 5-6%, it is standby；
（2）The preparation of glue：In parts by mass, by 15-25 parts of soybean protein raw material, 50 parts of water, 12-16 parts of Tea Polyphenols modifying agent, 10 parts of talcum powder, stirs after the 1.5-2.5 parts of mixing of 2.5-4 parts of starch and anion surfactant, obtains soybean protein Glue is standby；
（3）Mixing：After obtained straw raw material is mixed with soybean protein glue, stir；
（4）Precompressed：In hot pressing die, temperature is kept for 100-110 DEG C, applies 1.5Mpa pressure, precompressed 5 minutes；
（5）Bake pressure：Pressurize 200-300kg on heating press, bake pressure shaping；
（6）Dry：Temperature control keeps ventilation 12-15 hours at 35-45 DEG C, you can.
The present invention solves crop straw burning and stacks what is caused due to make use of agricultural stalk class discarded object as raw material Problem of environmental pollution, coordinates soybean protein glue as adhesive, and coordinate certain materials ratio and secondary pressurized technique so that The formaldehyde-free density boards of the present invention not only more health environment-friendly, and with the characteristics of intensity is high, humidity resistance is good.
Embodiment
With reference to embodiment, the invention will be further described.
Formaldehyde-free density boards and preparation method thereof, the formaldehyde-free density boards are therein with the cornstalk of recovery, rice straw, wheat straw One or more are raw material, using soybean protein glue as adhesive, wherein every cube of formaldehyde-free density boards include the soybean of double centner Protein adhesive.
Embodiment 1：The preparation method of formaldehyde-free density boards is：
（1）It is prepared by raw material：Selected wheat straw is cut off, boiling 1.5 hours at 150 DEG C, steamed wheat straw, which adds water, is crushed into grain Footpath is less than 3mm particle, then is dried, and makes its moisture control in 5-6%, standby；
（2）The preparation of glue：In parts by mass, by 15-25 parts of soybean protein raw material, 50 parts of water, 12-16 parts of Tea Polyphenols modifying agent, 10 parts of talcum powder, stirs after the 1.5-2.5 parts of mixing of 2.5-4 parts of starch and anion surfactant, obtains soybean protein Glue is standby；
（3）Mixing：After obtained straw raw material is mixed with soybean protein glue, stir；
（4）Precompressed：In hot pressing die, temperature is kept for 110 DEG C, applies 1.5Mpa pressure, precompressed 5 minutes；
（5）Bake pressure：Pressurize 250kg on heating press, bake pressure shaping；
（6）Dry：Temperature control keeps ventilation 12-15 hours at 35-45 DEG C, you can.
