Embodiment Construction

[0016] 1. Mix 60 parts of coarsely broken corn kernels, 2 parts of modifiers glyoxal, phosphorus oxychloride, benzyl chloride, castor oil and toluene diisocyanate, and 10 parts of water (60:10:10 by weight) and mix well , into a single-screw extruder, the screw D / L value is 25, the three-stage temperature is 95 ° C, 130 ° C, 160 ° C, and the rotation speed is 120 RPM. After extrusion, crush to 60 mesh for later use.

[0017] 2, with various raw materials by weight percentage: bamboo pulp fiber 10, modified cornstarch (i.e. the product of step 1) 70, plasticizer calcium stearate (zinc) 1, softening agent (methyl silicone oil) 2, hair Foaming agent (azodicarbonamide) 7, preservative (potassium behenate) 0.3, waterproofing agent (wax emulsion) 2, filler (calcium carbonate) 7.7, and mix evenly in a mixer.

[0018] 3. Send the uniformly mixed materials into the twin-screw extruder. The process parameters of the twin-screw extruder are: the screw D / L value is 20, the temperature of...

Abstract

A phytopolyose sponge is prepared from phytopolyose through adding filler, plasticizer, softening agent, foaming agent, water-proofing agent and antiseptic, high-temp. fusing-plasticizing and puffingin an extruder ,and shaping by die extruding.

Description

technical field [0001] The invention relates to a high-temperature extruded and expanded plant polysaccharide sponge, and also relates to a preparation method of the plant polysaccharide sponge. Background technique [0002] With the further development of industrial civilization, people's awareness of environmental protection of industrial products is getting stronger and stronger, and the requirements for environmental protection are getting higher and higher. At present, the sponge products on the market are mainly polyurethane sponge products. Whether it is a large amount of organic solvents used in the production process of such products, or the residue of solvents in the products, it has caused a great negative impact on the living environment and living environment of human beings, and even endangers the health of users. Polyurethane sponge products are non-biodegradable and non-recyclable. The direct consequence is that the amount of solid...
