Embodiment Construction

[0011] This additive is a compound: it is composed of ethylene glycol, glycerin, polyoxyethylene stearate, fatty alcohol polyoxyethylene ether, and silicone compound.

[0012] Components (unit, KG) of an auxiliary agent that can improve the mechanical properties (adhesion, abrasion resistance) of ordinary starch:

[0013]

[0014]

[0015] Described fatty alcohol polyoxyethylene ether is: emulsifier (nonionic surfactant), and its melting point is 20 ℃. The polyoxyethylene stearate is an emulsifier; its melting point is 40°C. The ethylene glycol is a solvent. The glycerol is a solvent. The silicone compound is a softener.

[0016] Auxiliary preparation method

[0017] Put the above materials into the container step by step, emulsify step by step with a high-speed emulsifier, then add each emulsified component into the same container, and then further emulsify into an emulsion, that is, the finished product.

[0018] Detailed additive preparation method: According to ...

Abstract

The invention discloses an additive capable of improving the mechanical properties of ordinary starch. The additive comprises the following components in parts by mass: 15-30 parts of glycol, 20-30 parts of glycerin, 20-30 parts of fatty alcohol-polyoxyethylene ether, 10-20 parts of stearic acid polyoxyethylene ether and 5-10 parts of an organic silicon compound, wherein the melting point of the fatty alcohol-polyoxyethylene ether is 20 DEG C, and the melting point of the stearic acid polyoxyethylene ether is 40 DEG C. A preparation method of the additive comprises the following steps: adding the materials into containers in different steps, emulsifying by using a high-speed emulsifier in different steps, adding the emulsified components into one same container, and further emulsifying, thereby obtaining an emulsion, namely, a finished product. By adopting the additive, the mechanical properties (adhesion property and wearing resistance) of the ordinary starch can be improved.

Description

technical field [0001] The invention relates to an auxiliary agent capable of improving the mechanical properties of ordinary starch and a preparation method thereof. Background technique [0002] PVA (i.e. polyvinyl alcohol), starch, propylene, and wax flakes are generally used as the main slurry in the existing slurry formulations. However, this type of slurry has poor miscibility and poor film-forming integrity, especially for polyester-containing warp yarns. , the protective effect is not ideal. Propylene-based slurry has the disadvantage of moisture absorption and stickiness. PVA biochemical treatment takes a long time, which takes 900 days, and it is designated as unclean slurry by the Ministry of Environmental Protection. As a renewable plant resource, starch has a wide range of sources, low price, good biocompatibility and environmental friendliness, and has been used as an important size in the textile industry. However, the starch size film is hard and brittle, a...
