Problems solved by technology

[0004] The pulp slime is too soft, and the finished pulp slime after molding is not firm enough, and the shape of the mold is quite different; the pulp slime is sticky to the hand, and it is not easy to release the mold after pressing the film. The problem of pulp slime sticking to the mold wall often occurs, which affects the finished product effect, unable to meet the molding requirements of manual molds

Embodiment 1

[0027] A paper pulp slurry for manual molding is made of the following components in terms of weight percentage, 44% paper pulp, 18% corn starch, 21.4% manual paste, 14% cooked gypsum powder and 2.6% edible oil.

[0028] The preparation method comprises the following steps:

[0029] (1) Pulp manufacturing: shred waste paper (waste paper includes: printing paper, newspaper, handmade paper, rice paper, etc.) Paper; Pour all the materials in the container into the mixer, and then pour them into the sieve basin after mixing; finally press the pulp with your hands to make the water in the pulp flow out of the sieve basin, and the approximate dehydration amount is 80% to 85%. That's it.

[0030] (2) Material mixing and stirring: mix paper pulp, corn starch, and manual paste in proportion and then fully stir, so that paper fibers, starch, and paste can be more compact, and the fiber network can be firmer; then add cooked gypsum powder and stir, cooked gypsum After the powder is add...

Embodiment 2

[0035] A paper pulp slurry for manual molding is made of the following components in terms of weight percentage: 41% paper pulp, 20.6% corn starch, 21.2% manual paste, 14% cooked gypsum powder and 3.2% edible oil.

[0036] The preparation method is the same as in Example 1.

[0037] After the pulp mud material is manually molded, a block with a diameter of about 3 cm is obtained. After 48 hours of drying in the air at room temperature at 20-30°C, apply water-based paint on the surface and let it stand for about 5 minutes. The final molded product has a very smooth appearance, fast demoulding speed, fine surface, light weight, and is not easy to break or be affected by moisture.

Embodiment 3

[0039] A paper pulp slurry for manual molding is made of the following components in terms of weight percentage, 41% paper pulp, 18.8% corn starch, 22% hand paste, 16% cooked gypsum powder and 2.2% edible oil.

[0040] The preparation method is the same as in Example 1.

[0041] After the pulp mud material is manually molded, a block with a diameter of about 3 cm is obtained. After 48 hours of drying in the air at room temperature at 20-30°C, apply water-based paint on the surface and let it stand for about 5 minutes. The final molded product has a relatively full appearance, a high degree of molding reduction, small voids, strong toughness, clear surface texture, light weight, and is not easy to break or be affected by moisture.

[0042] Such as figure 1 , figure 2 As shown, the finished pulp mud product without adding cooked gypsum powder: the molded product is obviously soft and slumped, and the shaping effect is poor.

[0043] Such as image 3 , Figure 4 As shown, t...

Abstract

The invention relates to paper pulp mud for manual molding, the paper pulp mud is prepared from the following components in percentage by weight: 40 to 45 percent of paper pulp, 18 to 24 percent of corn starch, 20 to 24 percent of manual paste, 12 to 16 percent of cooked gypsum powder and 2.2 to 3.2 percent of edible oil. After the cooked gypsum powder is added, the hardness and the plasticity of the paper pulp mud are improved, and the paper pulp mud is not easy to break even though collision occurs; and after a proper amount of edible oil is added, on one hand, the paper pulp mud does not stick to hands, and on the other hand, the paper pulp mud serving as a manual molding material has the advantage of easiness in demolding.

Description

technical field [0001] The invention relates to the technical field of manual molding, in particular to a pulp mud for manual molding and a manual molding method. Background technique [0002] Pulp molding mainly uses handmade pulp mud as the raw material, puts the handmade pulp mud into the mold for manual pressing, and obtains the finished product of pulp mud. [0003] Existing manual pulp mud components usually include foam powder, water, paper pulp and paste, colloid, fiber (and feldspar) etc., are mostly used in people's kneading materials. It has the following technical problems: [0004] The pulp slime is too soft, and the finished pulp slime after molding is not strong enough, and the shape of the mold is quite different; the pulp slime is sticky to the hand, and it is not easy to release the mold after pressing the film. The problem of pulp slime sticking to the mold wall often occurs, which affects the finished product The effect cannot meet the molding requireme...
