Description
Technical field
The invention belongs to packaging material processing technique fields, more particularly to prepare composite packaging material with waste paper, wood bamboo material
The technique of material.
Background technique
A large amount of generations of waste paper, from our daily life, such as household electrical appliance consume based food, electronic product, with
And the leftover pieces waste paper that packages printing industry generates.The waste paper recovery and reuse technology in China is started late, and mode is more single,
Raw material after the recycling of part waste paper as papermaking are recycled, partially the hypocarp to be simple to manufacture, coarse, egg tray etc
Low grade products, waste paper recovery and reuse technology could not industrial goods pack and food packaging on obtain it is more effective, a greater amount of
Using application technology could not further be broken through, and the leading enterprise of waste paper recycling and reusing industrialization can be driven fewer and fewer.
In China, in electronic product packaging, timber packaging accounts for about 80%, annual to consume more than 1,000 ten thousand m3 of timber, accounts for China
1/6 or so of merchantable timber yield, and most of is all high-quality timber.To accelerate to promote electromechanical product packaging section material Dai Mugong
Make, save high-quality timber, protect forest resources and ecological environment, research and development waste paper recovery and reuse technology and equipment have
Significance is both the requirement built a resource-conserving and environment-friendly society, and even more promotion China's electronic product packaging rises
Grade, accelerates actual needs in line with international standards.
In China, 2008 annual output of artificial bamboo board is up to 3,000,000 m3,3% left and right of Zhan Quanguo wood-based plate annual output.
The exploitation of bamboo fiber board not only makes bamboo wood obtain large-scale industrial utilization, improves the use value of bamboo wood, and suitable
The imbalance between supply and demand of China's timber is alleviated in degree.But we are it must be observed that the resource utilization of bamboo wood is still relatively low.I
Utilization rate level of state's bamboo timber resource is substantially between 20~50%.If the utilization rate of bamboo of bamboo flooring only has 20% or so,
Utilization rate of bamboo in bamboo wood cement formwork manufacturing process is about 50% or so, and the utilization rate of bamboo of thinly-sliced meagre bamboo is only about
Have 15% or so, the bamboo utilization of recombining bamboo is about in 50-60% or so.The low reason of utilization rate of bamboo be on the one hand due to
Bamboo bar self structure is determined, on the other hand closely related with processing technology and technology.The utilization efficiency of bamboo wood is low to be presented as production
Than high, product purpose is single, while also illustrating the irrationality on product structure for the functions of product, price.
Summary of the invention
The present invention in view of the above technical problems, provides the technique for preparing compound package material with waste paper, wood bamboo material.
The technical scheme adopted by the invention is as follows: the technique of compound package material, the system are prepared with waste paper, wood bamboo material
The technique of standby compound package material the following steps are included:

The weight ratio for expecting waste paper material obtained in A and step S1 is 1:3；Boiling is carried out to raw material using sulfate process, when boiling is added
Tapioca, antibacterial agent and reinforcing agent are added biological enzyme in obtained paper pulp and polyacrylamide are beaten, obtained paper
Slurry isolates long fibered pulp using fractionating screen；
S5, cardboard molding: mixed pulp is injected in flat plate mold, according to required thickness, close under the conditions of 150-170 DEG C
Downward pressing formation is spent, is dried after demoulding；
S6, preparation bamboo rib；By bamboo stalk it is transversal be thick bamboo tube, then by thick bamboo tube longitudinal direction subdivision, be processed as with bamboo blueness and tabasheer
Long narrow bamboo chip；
S7, bamboo rib superficial charring；Bamboo chip is put into retort or carbonizing kiln carbonizes, and bamboo chip after charing is processed as
Thin bamboo strips used for weaving or bamboo silk；
S8, antimicrobial treatment；Thin bamboo strips used for weaving or bamboo silk are immersed in the dicyandiamide saturated solution for carrying silver-colored titanium dioxide containing antibacterial agent,
Solution temperature is 20-50 DEG C, and carrying silver-colored titanium dioxide concentration is 10-200g/kg, soaking time 0.5-3h, is compressed using being passed through
The mode of air or circulating pump keeps the even density of solute in solution；
S9, preservative treatment；Thin bamboo strips used for weaving or bamboo silk are taken out, drained, and is immersed in the phosphoric acid saturated solution containing preservative, is adopted
With high temperature-low temperature impregnation technique, in-situ synthesized reaction of the fire retardant inside thin bamboo strips used for weaving or bamboo silk is realized, additive amount is to occur
Until precipitating；
S10, by bamboo rib, ratio is vacantly arranged on flat plate mold in certain intervals, is put into steel wire above bamboo rib
Net repaves one layer of quartz mortar, and imposes resin based adhesive, mixed pulp or mixing bamboo pulp or paper bamboo mixing slurry is injected flat
Board mold, to its natural drying, and presses downwards according to required thickness, and the left and right sides while pressing formation are dried into after demoulding
For bamboo rib stiffening plate, by resulting cardboard and bamboo rib stiffening plate by the required specification for cutting into and being mutually matched, then pass through high intensity
After adhesive carries out pressure bonding, upper water-repellent paint is coated in the bamboo rib stiffening plate plate face of the closely sealed plate of single layer.
Preferably, in the step S4, when using kraft cooking, digestion time 3-4h, boiling temperature 150-
