The waterproof additive specially for pulp molding consists of paraffin, rosin and water, and includes liquid waterproof additive and solid waterproof additive in different water content. It features that the composiion also includes anhydrous sodium carbonate and ammonium stearate and carboxyl methyl cellulose. The molded paper product with the said waterproof additive may be dried in the sun or in the air, and has excellent waterproof effect. The molded paper product with the said waterproof additive is the ideal substitute of foamed polystyrene product.
Description
Technical field:
The present invention relates to the paper making technology, particularly disclose a kind of water-proof additive speically for pulp moulding and preparation method thereof, be applied in production fields such as tableware, industrial goods packing, agricultural flowerpot.
Background technology:
Moulded paper pulp product is to be that basic raw material is equipped with various additives and makes a kind of novel package inner lining material with waste paper; this product has its good protection, shockproof, resistance to compression, electrostatic-proof function to products to be packaged on function; its waste is recyclable to be utilized again; bury even abandon; also perishable and resolve into the natural fiber material, be the ideal substitute of foaming polystyrene (EPS) goods.
In the production process of moulded paper pulp product, add a certain amount of waterproof additive, can change the part characteristic of product, make product have excellent waterproof, damp proof and moisture-proof function, part increases the hardness and the whiteness of product, strengthens the resistance to compression shockproof properties of product simultaneously.For example meet the wet deformation that water can not cause packing material of meeting in transit, products such as agricultural disposable flowerpot and seedling dish use the waterproof additive of inequality, the infiltration effect of may command product and be embedded in rotten resolving time in the soil.External large-scale paper mould production special manufacturer, the product drying mode adopts full-automatic flow production line behind the additive that uses, product moves in 150～180 ℃ track type baking oven voluntarily, drying and moulding, the additive that they use, on the high side, the working conditions harshness, product must be under the situation of 150 ℃ of hyperthermia dryings, waterproof effect is preferably just arranged, and the exsiccant product does not then have waterproof action under the normal temperature.
Summary of the invention:
Technical problem to be solved by this invention is: the moulded paper pulp product of the waterproof additive of use dries at normal temperatures or dries in the shade can good waterproof effect, and additive is easy to use, and stable performance is cheap.Technical scheme of the present invention is a water-proof additive speically for pulp moulding, component comprises paraffin, rosin, water, be divided into liquid repellent additive and solid-state waterproof additive according to water component content product, it is characterized in that also comprising in the component anhydrous sodium carbonate, ammonium stearate (emulsifying agent), carboxymethyl cellulose (auxiliary material), the proportioning of each component (per-cent % difference) is: liquid repellent additive: anhydrous sodium carbonate 1.8-2.4
Paraffin 8.0-8.5
Rosin 11-14
Ammonium stearate 0.8-1.2
