Abstract

The invention discloses modified bentonite capable of preventing insect damage. The modified bentonite is characterized by being prepared from the following raw materials in parts by weight: 90-95 parts of bentonite, 3-4 parts of crushed yellow cinnamon leaves, 2-3 parts of crushed ginkgo leaves, 2.5-3.5 parts of cationic starch, 0.6-1 part of terpilenol, 2-3 parts of peach gum, 5-7 parts of silica sol, 4-6 parts of natural rubber, 3-4 parts of mountain flour, 4-6 parts of monobutyl itaconate and 3-4 parts of modified kieselguhr. Due to natural substances of yellow cinnamon leaves, ginkgo leaves, peach gum and the like, the modified bentonite has a certain insect damage prevention and worm damage prevention and is safe and non-toxic; due to the added high-molecular polymers and modified kieselguhr, the bentonite is good in dispersity and compatibility, is very high in bonding force when being used in a coating, does not degrade the physical property of a product when being massively used, and is capable of preventing worm damage.

Description

A kind of modified alta-mud that can insect-pest and preparation method thereof

Technical field

The present invention relates to industrial filler field, particularly a kind of modified alta-mud that can insect-pest and preparation method thereof.

Background technology

The bentonite ore resource of China is very abundant, and reserves occupy first place in the world, and account for 60% of world's total amount, prognostic resources more than 7,000,000,000 tons, and wide to distribute, bury shallow, easy digging and great variety of goods as feature.Wilkinite and the remodeling product of purifying thereof all have some superior characteristics to some extent, these characteristics mainly contain swelling property, wetting ability (or lipophilicity, as organobentonite), adsorptivity, cationic exchange, catalytic activity, dispersiveness, suspension, cementability, thixotropy, stability, nontoxicity.Along with scientific and technical development, people deepen gradually to the understanding of wilkinite crystallization property and physicochemical property, and the use of wilkinite aspect industrial and agricultural production and scientific research is increasingly extensive.It has application prospect very widely as binding agent, suspension agent, thickening material, thixotropic agent, flocculation agent, stablizer, purification and decoloration agent, filling agent, catalyzer and support of the catalyst in fields such as metallurgy, machine casting, probing, petrochemical complex, light industry, Agriculture, forestry And Animal Husbandry, construction work, environmental protection.

Summary of the invention

The object of this invention is to provide a kind of modified alta-mud that can insect-pest and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A kind of modified alta-mud that can insect-pest of the present invention, made by following concrete steps:

(1) wilkinite, pulverizing leaf of Yellow cinnamon, pulverizing Ginkgo Leaf, cationic starch, vermiculite power are mixed and added in shredder, grind 15-20 minute with the speed of 1500-2000 rev/min, take out and dry, pulverize porphyrize, cross 100-200 mesh sieve, obtain mixed powder stand-by;

(2) Terpineol 350, peach gum, silicon sol, natural rubber are put into mixing tank, be warming up between 80-90 DEG C, mix and blend half an hour, continue to add monobutyl itaconate, continue to be warming up to 130-160 DEG C, mix and pour out after 15-20 minute, obtain material modified;

(3) mixed powder is mixed with material modified, add suitable quantity of water, stir and grind 2-3 hour, form suspension stand-by;

(4) suspension is mixed with modification infusorial earth, stir 10-15 minute under 800-1000 rev/min, dry, be ground into 200-400 order powder and get final product.

The invention has the beneficial effects as follows: the present invention adds the crude substance such as leaf of Yellow cinnamon, Ginkgo Leaf, peach gum, there is certain insect-pest, Anti-moth-eating effect, safety non-toxic, add high molecular polymer and modification infusorial earth, make wilkinite there is good dispersiveness and consistency, have very strong bonding force as in coating, use in a large number, physicals and the energy that also can not reduce product are anti-insect.

Specific embodiments

Below by specific examples, the present invention is described in detail.

Modified alta-mud that can insect-pest, by following weight part (kilogram) raw material make: wilkinite 90, pulverize leaf of Yellow cinnamon 3, pulverize Ginkgo Leaf 2, cationic starch 2.5, Terpineol 350 0.6, peach gum 2, silicon sol 5, natural rubber 4, vermiculite power 3, monobutyl itaconate 4, modification infusorial earth 3;

Described modification infusorial earth by following weight part (kilogram) raw material make: diatomite 50, charcoal 4, sodium lignosulfonate 3, stearic acid 2, MALEIC ANHYDRIDE 4, lauryl methacrylate(LMA) 4, terpolycyantoamino-formaldehyde resin 5, tripoly phosphate sodium STPP 4, water 50; First preparation method adds diatomite, charcoal, lauryl methacrylate(LMA), water to stir, form suspension, add MALEIC ANHYDRIDE, terpolycyantoamino-formaldehyde resin, tripoly phosphate sodium STPP mix and blend 25-35 minute, then add all the other remaining components, under 1200-1500 rev/min of condition, stir, at 50-60 DEG C, dry, be ground into 200-400 order powder and get final product.
