Abstract
The invention discloses a water absorbent for plastic molding. The water absorbent comprises the following raw material components in parts by weight: 30-60 parts of carrier resin, 100-120 parts of inorganic oxide, 0.5-2.5 parts of graft modifier, 3-8 parts of flexibilizer, 2-5 parts of dispersing agent and 1.5-3.5 parts of stabilizer. The water absorbent for plastic molding has the beneficial effect of good water absorbability, is convenient to use, and is suitable for being used in molding of multiple plastic products.
Description
Technical field
The present invention relates to a kind of polymeric material field, specifically is that a kind of plastic shaping is used water-retaining agent.
Background technology
In plastic shaping processing, often run into the raw material that some makes moist, influence is produced, and also some raw material can absorb airborne moisture content.To making the difficult of forming process and causing the defective of these final product performances.These raw materials more typically have regeneration reclaimed materials, PS, ABS etc.These materials are used for plastic pipe, injection-molded item and the most common with regeneration reclaimed materials Production and Packaging film bag product.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of good water absorption, and plastic shaping easy to use is used water-retaining agent.
Technical scheme of the present invention is achieved in that a kind of plastic shaping uses water-retaining agent, and raw material is formed and mass fraction is: vector resin 30-60 part, inorganic oxide 100-120 part; Graft modification agent 0.5-2.5 part; Toughner 3-8 part, dispersion agent 2-5 part, stablizer 1.5-3.5 part;
Said vector resin is one or more in PS, nylon, linear low density polyethylene, the new LDPE (film grade);
Said inorganic oxide is Natural manganese dioxide, zinc oxide or barium oxide;
Said graft modification agent is silane coupling agent or phthalate ester coupling agent.
Said toughner is one or more in liquid paraffin, white oil, NO, dioctyl ester and the dibutylester.
Said dispersion agent is that Vilaterm is compound cured.
Said stablizer is calcium stearate, StNa or barium stearate.
The invention has the beneficial effects as follows: plastic shaping of the present invention is used the water-retaining agent good water absorption, and is easy to use, is adapted at using in the moulding of multiple plastics.
Embodiment
Below in conjunction with specific embodiment the present invention is further explained.
