Description

Technical Field

[0001] The invention relates to the field of degradable materials, and in particular to a degradable ecological glue and a synthesis method thereof. Background Art

[0002] In recent years, with the gradual improvement of the level of modern industrial construction, the requirements for environmental protection and sustainable development of chemical companies have become increasingly higher. While creating economic value, we need to pay more attention to environmental protection and minimize resource consumption and impact on the ecological environment. Therefore, degradable materials came into being. Degradable materials refer to organic materials that can be naturally decomposed. Under the action of microorganisms, biochemical reactions occur, causing changes in appearance, internal quality, and other aspects, and finally forming compounds in common forms in nature such as carbon dioxide and water;

[0003] The glue used for printing in the prior art is usually composed of a vulcanizing agent and an accelerator, etc. It does not have the property of being degradable, and is likely to cause environmental pollution after use. Therefore, we propose a degradable ecological glue and a synthesis method thereof. Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a degradable ecological glue and a synthesis method thereof.

[0005] The biodegradable ecological glue proposed by the invention comprises the following raw material percentages: 46% of natural polymer material, 25% of polylactic acid, 15% of polycaprolactone, 5% of plasticizer, 2% of defoamer, 3% of moisturizer, 0.5% of pH regulator and 3.5% of thickener.

[0006] Preferably, the natural polymer material may be cellulose starch.

[0007] Preferably, the polylactic acid and polycaprolactone are both biodegradable polymers.

[0008] The present invention also proposes a method for synthesizing a degradable ecological mortar, comprising the following steps:

[0009] S1: Pour 46% of natural polymer material, 25% of polylactic acid and 15% of polycaprolactone into a blender according to the proportion and stir and mix evenly for 20 minutes;

[0010] S2: Add 5% plasticizer to the mixer in S1 and stir at low speed for 10 min;

[0011] S3: Then, add 2% defoaming agent into the mixer in S2 and continue to stir and mix at a low speed to defoam the slurry inside the mixer;

[0012] S4: Add 3% of moisturizing agent to the mixer in S3 and continue to stir and mix at a low speed to keep the slurry moisture inside the mixer and keep the slurry warm and smooth, then add 0.5% of pH regulator and continue to stir to adjust the pH value of the slurry;

[0013] S5: After the slurry in S4 is mixed uniformly, adjust the speed of the mixer to 1500-1600r / min, then add 3.5% thickener and put it into the high-speed mixer at a speed of 1500-1600r / min for stirring to increase the viscosity of the slurry and achieve the effect of dispersion and thickening. After stirring and mixing evenly, a degradable ecological mortar is obtained.

[0014] Preferably, in S1, the rotation speed of the stirrer is 500-600 r / min.

[0015] Preferably, in S2, the addition of a plasticizer is used to improve the flexibility and cold and frost resistance of the slurry.

[0016] The present invention also proposes a printing process of a degradable ecological glue, comprising the following steps:

[0017] SA: Screen printing: Screen printing is done according to graphic design;

[0018] SB: Printing and scraping: Scrape the eco-paste evenly on the fabric through the screen made in SA, scrape 4-5 times, scrape twice each time to ensure full and smooth color;

[0019] SC: Drying and curing: The fabric with the eco-glue printed in SB is dried in a drying oven at 120-130℃ for 60 seconds. After drying 1-2 times, the eco-glue on the fabric is cured in the oven.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention synthesizes the ecological glue from some degradable raw materials such as natural high molecular materials and biodegradable polymers, which can be degraded by biodegradation. During degradation, the degradable materials will be decomposed by microorganisms into harmless substances such as water, carbon dioxide, organic matter, etc., which is pollution-free to the environment and meets environmental protection requirements.
