Abstract

The special sticky shellac for tea gardens and a preparation method thereof relate to a sticky shellac. The invention provides a sticky shellac mainly used in tea gardens with good sticking and catching ability and a preparation method thereof. The raw material composition and its mass percentage content are as follows: 60%-80% of polyisobutylene, 10%-30% of filler, 0.5%-5% of tackifier, and 1%-6% of attractant. During preparation, the attractant is firstly added in proportion to the polyisobutylene and stirred; the filler and the viscosifier are added, and then stirred evenly. Due to the use of non-polluting polymer binder polyisobutylene as the main agent, adding preferred tackifiers, fillers and attractants, etc., the sticky insect effect and cost-effectiveness are good, especially for large-scale pests in tea gardens. Even better, it is a kind of non-polluting sticky insect glue suitable for the production of organic tea gardens. If it is used in conjunction with other products such as yellow cardboard commonly known in the market, it can obtain an excellent effect of attracting and bonding tea garden pests.

Description

Special sticky shellac for tea garden and preparation method thereof

technical field

The invention relates to a sticky shellac, in particular to a sticky shellac mainly used in organic tea gardens and a preparation method thereof.

Background technique

Since tea is suitable for growing in areas with rich water and heat resources, virus and insect pests are more serious, which have a serious impact on tea production, especially large-scale pests, such as small green leaf cockroaches, whiteflies, thrips and aphids. Due to the poor sticky catch ability of the existing commercially available insect sticky boards, especially for larger pests, there are generally disadvantages such as difficult coating, easy aging, easy failure when exposed to water, and high price. Therefore cause tea farmers to use banned pesticides in large quantities, and tealeaves is a kind of food that directly soaks and drinks, and tealeaves pesticide residues have had a strong impact on people's health. For this reason must vigorously carry out tea tree pests adopting pollution-free control technology, to ensure the hygienic quality of tea.

Publication number is that the invention patent application of CN1847354 provides a kind of sticky shellac that is especially suitable for controlling pests. It is made of the following raw materials by weight: 20-35 parts of polypropylene, 15-25 parts of vegetable oil, 25-35 parts of rosin, and 20-35 parts of animal gum or animal wax.

The invention patent application with the publication number CN1911012 provides a kind of sticky shellac and its preparation method, which is formed by mixing rosin, castor oil and paraffin in a certain weight ratio. Similar products are difficult to operate due to the high viscosity, which can be used for the prevention and control of some plant pests in agriculture and forestry, especially for sticky paramecium climbing trees and making traps for sticking boards.

The invention patent application with publication number CN1067255 provides a kind of sticky insect adhesive. Its main feature is that it is made by mixing natural rubber with additives. The natural rubber is solidified glue or latex, and the additives are diesel oil. The prepared adhesive has Ability to stick to pests. It is suitable for agricultural pest control, household mosquito control, anti-theft and so on.

There are few reports about the sticky shellac used in tea gardens.

Contents of the invention

The object of the present invention is to provide a kind of sticky shellac mainly used in tea gardens with good sticking and catching ability and its preparation method.

The raw material composition of tea garden sticky shellac and its content by mass percentage are:

The polyisobutylene is 60%-80%, the filler is 10%-30%, the tackifier is 0.5%-5%, and the attractant is 1%-6%.

The molecular weight of described polyisobutylene is preferably＜1,800,000, filler is selected from silicon dioxide or calcium oxide, tackifier is selected from carboxymethyl cellulose (CMC), rubber or carrageenan etc., attractant is selected from sugar, Fat-soluble incense, ethyl acetate or fruit and vegetable extracts, etc.

The preparation method of tea garden sticky shellac of the present invention comprises the following steps:

1) Add the attractant to polyisobutylene in proportion, and stir evenly;

2) Add filler and tackifier, and stir evenly again.

Because the tea garden sticky insect glue of the present invention mainly adopts the non-polluting polymer binder polyisobutylene, and adds preferred tackifiers, fillers and attractants, etc., it has been proved by field application that its armyworm effect and cost performance etc. are better than similar products on the market (such as yellow cardboard produced in Taiwan, China, etc.), especially the ability to stick and catch larger pests in tea gardens is significantly better than similar products on the market, and the price is only about the same as that on the market. 1/4 of the product. Therefore the tea garden sticky shellac described in the present invention is a kind of non-polluting sticky shellac suitable for the production of organic tea gardens. If it is used in conjunction with other products such as yellow cardboard commonly known as the market, it can obtain excellent lure and bonding tea garden pests. Effect.

Detailed ways

The following examples will further illustrate the present invention.

Add the attractant white granulated sugar into the polyisobutylene in proportion, stir evenly, then add the filler silicon dioxide and the tackifier CMC, stir again evenly, and get the tea garden sticky shellac. According to mass percentage, the content of each raw material is 60% of polyisobutylene, 30% of filler silicon dioxide, 5% of tackifier CMC, 5% of attractant white granulated sugar, and the molecular weight of polyisobutylene is less than 1.8 million.

In the above embodiment, the attractant can be replaced by glucose, the added filler can be replaced by calcium oxide, and the tackifier can be replaced by rubber. According to mass percentage, the content of each raw material is polyisobutylene 69.5%, filler calcium oxide 26%, tackifier rubber 0.5%, attractant glucose 4%, and the molecular weight of polyisobutylene is less than 1.8 million.

In the above embodiment, the attractant can be changed to fat-soluble incense, the added filler is still calcium oxide, and the tackifier is changed to carrageenan. According to mass percentage, the content of each raw material is polyisobutylene 72.5%, filler calcium oxide 22%, tackifier carrageenan 2.5%, attractant fat-soluble fragrance 3%, and the molecular weight of polyisobutylene is less than 1.8 million.

In the above examples, the attractant can be changed to ethyl acetate, the added filler can be changed to silicon dioxide, and the tackifier can be changed to CMC. According to mass percentage, the content of each raw material is 78% of polyisobutylene, 18% of filler silicon dioxide, 3% of tackifier CMC, 1% of attractant ethyl acetate, and the molecular weight of polyisobutylene is less than 1.8 million.

In the above embodiments, the attractant can be replaced by fruit and vegetable extracts, the added filler is still silicon dioxide, and the tackifier can be replaced by rubber. According to mass percentage, the content of each raw material is 80% of polyisobutylene, 10% of filler silicon dioxide, 4% of tackifier rubber, 6% of attractant fruit and vegetable extract, and the molecular weight of polyisobutylene is less than 1.8 million.
