2.1 Infrared Analysis.

Infrared tests were carried out on Hydroxyethyl Cellulose Sigma (HEC), unmodified polyurethane movie (WPU), as well as changed polyurethane movie (HEC-WPU). It can be seen from curve A in Number 1 that 420 ~ 750cm-1 is the intra-ring vibration absorption peak of the sugar ring, which is the characteristic group of HEC particle. It can be seen from the contrast of contours B and C that both are at 3313., 1723, 1592cm-1 appeared infrared absorption heights. Among them, the stretching vibration of -NH- at 3313cm-1, the extending vibration optimal of -NH-C =O- at 1723cm-1, and also the flexing vibration optimal of -NH- at 1592cm-1, it can be seen that -OH Responds with -NCO as well as creates a urethane bond. At the same time, the peak shapes of contours B as well as C are obviously various at 480-690 cm-1, which may be brought on by the overlapping of the vibration absorption peak of the glucose ring in the HEC molecule and also the absorption optimal of the polyurethane there. Infrared analysis can prove that HEC particles are successfully grafted right into the polyurethane molecular chain, as well as the acquired product is the target item.

2.2 Impact of hydroxyethyl.

cellulose on emulsion residential properties.
It can be seen from Table 1 that with the rise of HEC content, the viscosity of the polyurethane finish progressively raises, as well as the solid web content of the emulsion very first increases and after that decreases. This might be because of the response of hydroxyl groups in HEC with isocyanate groups to present cellulose molecular chains into polyurethane particles, and also the molecular weight and also section length boost. The expanding sectors are much more susceptible to complexity, causing raised viscosity. At the same time, the unreacted hydroxyl groups in HEC form hydrogen bonds with polyurethane to prevent the activity of molecular chains, thus further enhancing the thickness of the system. When the HEC content boosts to a particular degree, the thickness of the system is as well large, the emulsification procedure is difficult, the security of the resulting solution becomes bad, and the storage time comes to be shorter.

2.3 Impact of Hydroxyethyl Cellulose Sigma on film residential properties.

The buildings of the water-based polyurethane movie with different HEC materials are listed in Table 2. From Table 2, it can be seen that the pencil firmness of the film is enhanced after including hydroxyethyl fiber, the water absorption efficiency is reduced first and afterwards boosted, and also the bond degree is boosted. The fad is to enhance initial and afterwards lower. This is since the hydroxyl groups in cellulose can react with the isocyanate teams in the polyurethane prepolymer to create a cross-linked structure, therefore boosting the pencil solidity and also bond properties of the film, and the cross-linked framework also makes it tough for water particles to get in the molecular chain void. middle. When the quantity of cellulose included is also huge, unreacted hydroxyl groups remain in the emulsion, which adversely impacts the hardness, water absorption as well as attachment of the polyurethane film. The modified polyurethane done finest when the cellulose content was 0.5%.

As an eco-friendly finish, waterborne polyurethane has come to be the focus of research study on its adjustment. In this paper, TDI, N210, etc are utilized as the main basic materials to prepare the polyurethane prepolymer beforehand. Hydroxyethyl Cellulose Sigma was made use of as modifier to react with prepolymer, and also the impact of hydroxyethyl cellulose content on the properties of WPU emulsion and film was studied. The examination results program that the enhancement of HEC can improve the pencil hardness, attachment and also various other homes of the WPU film. When the cellulose web content is 0.5%, the film performance is best.
