Abstract
The invention belongs to the technical field of plates, and particularly relates to a manufacturing method of a fiberboard. After cellulosic material is crushed, an adhesion agent is added and mixed evenly, firstly pre-compaction is carried out, then thermo-compression formation is performed, wherein the pre-compaction pressure is 28kg/cm<2>, the pre-compaction time is 90s per centimeter of plate blank, the thermo-compression pressure is 80kg/cm<2>, the thermo-compression temperature is 800 DEG C, the thermo-compression time is 45s per centimeter of the plate blank, and cellulose acetate (CA) serves as the adhesion agent. The manufacturing method of the fiberboard has the advantages that compared with a traditional fiberboard, harm of formaldehyde is eliminated fundamentally, and due to the fact that the used adhesion agent is waterproof, the fiber board is good in water resistance.
Description
Technical field
The invention belongs to the sheet material technical field, specifically a kind of manufacture method of fiberboard.
Background technology
Fiberboard is take string as primary raw material, the product that the operations such as process fiber separation, moulding, drying and hot pressing are made.The soft construction sector that is widely used in makes sound and thermal insulating material, for example with being wallboard, partition wall and ceiling; Hardboard is widely used in the aspects such as construction and decoration and Furniture manufacture.Its production technology exists serious contaminated wastewater at present, and general every cubic metre of product need discharge industrial wastewater 40-50 ton, and energy consumption is high, and water resources consumption is very large.The dry production fiberboard must adopt adhesive, and adhesive commonly used has phenolic resins, arteries and veins urea formaldehyde etc.Owing to often containing free formaldehyde in these resins, therefore the fiberboard made from dry method in use can discharge the carcinogens such as formaldehyde.With its decorated house or after making furniture, become the invisible killer who affects health of people.
Summary of the invention
For overcoming the above-mentioned drawback of fiberboard, the invention provides a kind of manufacture method of pollution-free fiberboard.
Technical scheme of the present invention is as follows: a kind of autofrettage of fiberboard, and after cellulosic material is pulverized, add adhesive to mix thoroughly, first carry out precompressed, hot repressing moulding; Described preload pressure is 28Kg/cm
2, squeeze time is thick 90 seconds of every mc slab; Described hot pressing pressure is 80Kg/cm
2, temperature is 800 ℃, hot pressing time is thick 45 seconds of every cm slab; Described adhesive adopts cellulose acetate CA.
After pulverizing, crosses described cellulosic material 50 mesh sieves.
Described cellulosic material can be wood chip, plant stalk.
The fiberboard that utilizes the present invention to make, its quality index can reach the quality requirement of GB medium density fibre board (MDF) after testing.
Beneficial effect of the present invention is, compares with the traditional fibre plate, fundamentally eliminated the harm of formaldehyde.Adhesive used has a water resisting property, therefore fiberboard water-tolerant of the present invention.
The specific embodiment
Embodiment 1
Maize straw 100kg was pulverized 40 mesh sieves, added described adhesive 4kg, mixed thoroughly; Mat formation into a slab, at 28Kg/cm
