Embodiment 1

[0034] Crush the Suaeda salsa seed cake, then grind it to a fine powder, pass through a 120-mesh sieve, take 6.0 g of the Suaeda salsa seed cake powder, put it in 500 ml of boiling water, cook for 30 minutes, and then cool down to 65-75 °C.

[0035] Weigh 4.0g sodium dodecylbenzene sulfonate, standby; Fill the water of 100ml in the beaker, place on the constant temperature magnetic stirrer, weigh 3.0g sodium carboxymethylcellulose, under the situation of constant stirring, Sprinkle the sodium carboxymethylcellulose into the beaker slowly and evenly to dissolve the sodium carboxymethylcellulose completely and set aside.

[0036] Put the Suaeda salsa seed cake powder solution with a temperature between 65-75°C on a constant temperature magnetic stirrer, and at a stirring speed of 1000r / min, first slowly add sodium dodecylbenzenesulfonate, and then slowly add The sodium carboxymethyl cellulose solution was stirred rapidly for 20 minutes; then, the stirring speed was adjusted to 2...

Embodiment 2

[0040] Crush the Suaeda salsa seed cake, then grind it to a fine powder, pass through a 120-mesh sieve, take 10.0 g of the Suaeda salsa seed cake powder, put it in 400 ml of boiling water, cook for 30 minutes, and then cool down to 65-75 °C.

[0041] Weigh 4.0g sodium dodecylbenzene sulfonate, standby; Fill the water of 100ml in the beaker, place on the constant temperature magnetic stirrer, weigh 8.0g sodium carboxymethylcellulose, under the situation of constant stirring, Sprinkle sodium carboxymethylcellulose into the beaker slowly and evenly to completely dissolve the sodium carboxymethylcellulose, and set aside; take another beaker, fill it with 100ml of water, weigh 4.0g of polyvinyl alcohol, and mix it while stirring Slowly add this product to cold water at about 20°C to fully swell and disperse, then heat up to 95-100°C to accelerate dissolution until the solution no longer contains tiny particles, and then filter impurities through a 60-mesh stainless steel sieve befor...

Embodiment 3

[0046] In this example, the preparation steps of the bio-environmental-friendly binder are the same as in Example 1, only the ratio of the raw materials required for the preparation of the bio-environmental-friendly binder is changed.

[0047] Each raw material composition and proportioning required in the preparation process are as follows respectively: (g)

[0048] Suaeda seed cake powder 6.0;

[0049] Sodium dodecylbenzenesulfonate 3.0;

[0050] Sodium Carboxymethyl Cellulose 10.0;

[0051] Potassium sorbate 5.0;

[0052] Clear water 600.0.

[0053] Table 1 shows the performance test results of the bio-environmentally friendly adhesive prepared in this example.

Abstract

The invention provides a biological environment-friendly adhesion agent which is mainly prepared from Suaeda glauca Bge seedcake, matched with a surfactant, a thickener and an adhesive. The adhesion agent is applicable to the adhesion of soil sand grains to form a consolidation layer to prevent storms and dust. In addition, the adhesion agent is also can be used for adhering cartons, paper, plywood and the like. The invention also provides a preparation method of the adhesion agent. The sources of Suaeda glauca Bge seedcake which is the raw material of the adhesion agent are wide and the prepared adhesion agent is nontoxic, harmless, green and environment-friendly and has significant economic and social benefits.

Description

technical field [0001] The invention relates to a binder material, in particular to a bio-environmental protection binder with suaeda seed cake as the main raw material. Background technique [0002] Binders are widely used in various fields, such as briquette binders, pellet binders, plywood binders and sand-fixing binders. The most widely used binders are "synthetic binders" produced by polymer chemistry and petrochemistry. [0003] In the field of sand fixation, binders are mainly used in deserts and areas with severe wind erosion of the soil. They are used to bond sand particles. The purpose is to form a consolidated layer and prevent dust from wind and sand. Traditional sand-fixing binders can be divided into: cement slurry, water glass, petroleum products and polymer superabsorbent resin. These sand-fixing binders can fix the surface sand and have certain stability and water retention, so as to achieve the purpose of fixing quicksand and controlling desertification l...
