Specific embodiment
The present invention will be described in detail below.
The invention provides a kind of preparation method of anti-lost powder paper mould, comprise the steps：
S1. by levels be 1 ~ 3% poly-vinyl alcohol solution, 1 ~ 5% water-borne acrylic resin solution press 1：1 ~ 3
Ratio is mixed into solution mixture；
S2. solution mixture is added in paper pulp with the speed of 10-50g/ second, its addition is the 0.1 of pulp quality
~ 2%, during adding solution mixture, it is stirred simultaneously；
S3. the pulp material after being sufficiently mixed stirring is delivered to vacuum mould-suction shaping station；
S4. by vacuum mould-suction machine adsorb pulp material and carry out dehydration form l Water Paper base；
S5. l Water Paper base is delivered to shaper to carry out shaping, be dried and shaping, after shaping, form moulded paper pulp product.
In this preparation method, by levels be 1 ~ 3% poly-vinyl alcohol solution, 1 ~ 5% water-borne acrylic resin molten
Liquid presses 1：1 ~ 3 ratio is mixed into solution mixture, and then, the solution mixture that scope is obtained according to the above ratio is with 10-50g/
Second speed be added in the paper pulp of vacuum mould-suction machine to be delivered to, the addition of its solution mixture be pulp quality 0.1 ~
2%, in order that described solution mixture is sufficiently mixed with paper pulp, during adding solution mixture, need to carry out simultaneously
It is sufficiently stirred for, so that solution mixture is mixed with paper pulp fully, finally, the paper pulp mixing is become by vacuum mould-suction machine
Type, dehydration, sizing, drying and shaping, finally be obtained moulded paper pulp product it is emphasized that：Above-mentioned molding, dehydration, fixed
In the operation of type, drying and shaping, existing operation can be adopted, this moulded paper pulp product makes paper in the presence of polyvinyl alcohol
The surface-brightening of slurry molding, make, between the fiber of paper mould, there is stronger cohesive force, and described water-borne acrylic resin can
To prevent the intrusion of during normal use dampness, it is to avoid dampness penetrates into paper mould internal influence cohesive force, so that paper pulp
Moulding article not dry linting in conventional use, improves the range of moulded paper pulp product.
Mix with paper pulp to improve solution mixture further, in the step of S2, the speed controlling of described stirring exists
800-2000 rev/min.
Generally, it, during paper pulp is prepared in pulverizing, is generally carried out under room temperature, in order that described poly-vinyl alcohol solution
Alcoholysis is occurred to act in follow-up operation further, the raw material of described poly-vinyl alcohol solution is polyvinyl alcohol 1799 and polyvinyl alcohol
1788 press 1：1 ~ 2 ratio mixing.That is, this poly-vinyl alcohol solution employ the polyvinyl alcohol of two kinds of different models by than
Example is mixed to prepare, and wherein polyvinyl alcohol 1799 is different from the alcoholysis degree of polyvinyl alcohol 1788, and described polyvinyl alcohol 1799 is complete
Alcoholysis, complete alcoholysis need to be warmed to 95 degree about and just can be completely dissolved；And described polyvinyl alcohol 1788 is partial alcoholysis, no matter
In cold water, still can soon dissolve in the hot water, water solublity preferably so that polyvinyl alcohol 1788 can quickly with institute
State the further mixed dissolution of paper pulp, when paper pulp enters in sizing, drying and trimming, paper mould enters into high-temperature process
In, because dry and shaping temperature typically all reaches more than 100 degrees Celsius, so polyvinyl alcohol 1799 is because the rising of temperature
And there is alcoholysis, so that forming stronger cohesive force between the fiber of paper mould, the experiment proved that, polyvinyl alcohol 1799 He
The ratio of polyvinyl alcohol 1788 most preferably 1：1.5, the bonding force intensity between the fiber of described paper mould can be made best.
