Description
Technical field
The invention belongs to pulp technology for making paper, especially relate to a kind of leaching membrane paper manufacture craft.
Background technology
Leaching membrane paper is composite membrane coating material melting being coated in substrate surface by film machine.Leaching membrane paper because of its can grease proofing, waterproof, can heat seal and be widely used in multiple industries such as daily necessities, electronics, automobile foam, printing.
Current leaching membrane paper production technology is the material that low-density high-pressure polyethylene particle and food-grade body paper are composited through high temperature, high pressure substantially, and low-density high-pressure polyethylene particle is transparent, tasteless plastic grain, and body paper is the body paper of unstressed configuration antiseep.Because leaching membrane paper is all directly produce in indoor, surface one direct sum air contact, and in air, have much small particle and dust, therefore the product surface of this technique is adopted inevitably to produce some molecules and dust in process of production, thus cause leaching membrane paper surface to produce trickle stain, affect Product Visual effect; Especially when leaching membrane paper is used for the product relevant with diet such as Disposable paper cup, the appetite that stain will have a strong impact on people.For this reason, this problem also becomes matter of utmost importance urgently to be resolved hurrily in industry.
Summary of the invention
The problem to be solved in the present invention is to provide the high whiteness leaching membrane paper manufacture craft of the visual stain in a kind of effective minimizing leaching membrane paper surface, especially the leaching membrane paper manufacture craft of the daily necessities that applicable Disposable paper cup etc. are relevant with diet.
For solving the problems of the technologies described above, the present invention adds in leaching membrane paper raw material that whiteness is high, the titanium dioxide of strong covering power; Titanium dioxide is Powdered, be difficult to mix with the leaching membrane layer main raw material low-density high-pressure polyethylene particle of leaching membrane paper, therefore be difficult to prepare uniform and stable leaching membrane layer, titanium dioxide powder and low-density high-pressure polyethylene particle are passed through mixing, melting, granulation by the present invention according to a certain percentage, obtained compound particles, particle diameter, the density of this compound particles and pure low-density high-pressure polyethylene particle are all approximate, are therefore easier to mix with low-density high-pressure polyethylene particle; Again this compound particles and low-density high-pressure polyethylene particle are joined in homogenizer according to a certain percentage after obtained compound particles to mix and obtain mixing membrane coating material, mixing membrane coating material after mixing is joined film machine material chamber, the melting of mixing membrane coating material is made through heating devices heat, screw extruding, extrude through film machine die head, after through composite roll and chill roll, be compounded to form leaching membrane paper with base material.
As preferably, the titanium dioxide powder in compound particles preparation process and low-density high-pressure polyethylene granular mass are than being 3:7; The compound particles prepared under this ratio and low-density high-pressure polyethylene grain density, can processing type all similar, easily mix.
As preferably, described titanium dioxide particle shared mass percent in described mixing membrane coating material is 15-22%, and described low-density high-pressure polyethylene particle shared mass percent in described mixing membrane coating material is 78-85%; Within the scope of this, the leaching membrane paper of preparation both effectively can reduce visual stain number, did not affect again other performances of leaching membrane paper.
As preferably, die head temperature is 340-345 DEG C; Leaching membrane layer under this state is even and plasticizing is good, has good ductility and soffening.
As preferably, the type of cooling of chill roll is for adopting the 8-12 DEG C of rapid cooling method of cold water, and can either lower the temperature rapidly the degree of adhesion strengthening leaching membrane layer and base material like this, reason excessive temperature differentials does not cause damage to leaching membrane paper again.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, the leaching membrane layer of the leaching membrane paper that the present invention produces is white translucent shape, effectively reduce the visual stain quantity in leaching membrane paper surface.The dust thing of national Specification every square metre must not more than 5, and the leaching membrane paper dust thing that leaching membrane paper dixie cup technique of the present invention makes is reduced to every square metre and is no more than 2, substantially increases whiteness and the fineness of leaching membrane paper.
