Description

Technical Field

[0001] The invention relates to the technical field of resin preparation, in particular to a resin for a full-light-shielding awning tent and a preparation device thereof. Background Art

[0002] With the rise of outdoor leisure activities, the demand for canopy tents is growing. The resin material used in canopy tents can form a tight protective film on the surface of the tent fabric, improving the tent's waterproof, weather-resistant, and fold-resistant properties. The resin material can greatly improve the tent's performance, help the tent cope with different outdoor environments, extend the tent's service life, and provide people with a safe and stable resting place.

[0003] At present, the common resin materials used in canopy tents include PVC (polyvinyl chloride) resin, epoxy resin, water-based polyurethane resin, etc. Among them, PVC resin has good waterproof performance, but poor air permeability, and it will become brittle and hard in severe cold weather, and it is easy to crack. At the same time, when subjected to high temperature, it may release some harmful substances, which have a certain impact on the environment and human health. Epoxy resin has good adhesion and strength, good chemical stability, but the toughness of epoxy resin is relatively poor, and it is easy to crack when subjected to external force impact. Problems, and water-based polyurethane resin has good film-forming properties, excellent mechanical properties (can enhance the strength of tent fabrics), good weather resistance (can maintain good performance under different climatic conditions), and good wear resistance, so water-based polyurethane resin is widely used in tents, but its water resistance is poor. Despite continuous improvements, the water resistance of water-based polyurethane resin is still relatively weak. When it is exposed to a large amount of water or is in a humid environment for a long time, its performance may be affected to a certain extent (such as water penetration), and the use effect is not good.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] The first embodiment of the present invention provides a resin for a full-light-blocking awning tent. The resin for the full-light-blocking awning tent includes the following components in parts by weight: 10 to 15 parts of aromatic isocyanate, 30 to 35 parts of polyester polyol, 30 to 35 parts of polyether ester polyol, 10 to 15 parts of a small molecule diol chain extender, 0 to 5 parts of a small molecule triol chain extender, and 0.3 to 1 part of a catalyst, wherein the catalyst is any one of a titanate catalyst, an organic tin catalyst, and a fatty amine catalyst, and the polyether ester polyol is prepared by initiating polymerization of polyester and polyether with an initiator, wherein the initiator is a double metal cyanide complex catalyst, the small molecule diol chain extender is 1,4-butanediol, and the small molecule triol chain extender is trimethylolpropane.

[0039] Example 2

[0040] This is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it includes the following components in parts by weight: 12 to 15 parts of aromatic isocyanate, 32 to 35 parts of polyester polyol, 32 to 35 parts of polyether ester polyol, 12 to 15 parts of small molecule diol chain extender, 2 to 5 parts of small molecule triol chain extender and 0.3 to 0.8 parts of catalyst, the catalyst is any one of titanate catalyst, organic tin catalyst and fatty amine catalyst, the polyether ester polyol is prepared by initiating polymerization of polyester and polyether with an initiator, the initiator is a double metal cyanide complex catalyst, the small molecule diol chain extender is 1,4-butanediol, and the small molecule triol chain extender is trimethylolpropane.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] This is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it includes the following components in parts by weight: 12 to 13 parts of aromatic isocyanate, 32 to 33 parts of polyester polyol, 32 to 33 parts of polyether ester polyol, 12 to 13 parts of small molecule diol chain extender, 2 to 3 parts of small molecule triol chain extender and 0.5 to 1 part of catalyst, the catalyst is any one of titanate catalyst, organic tin catalyst and fatty amine catalyst, the polyether ester polyol is prepared by initiating polymerization of polyester and polyether with an initiator, the initiator is a double metal cyanide complex catalyst, the small molecule diol chain extender is 1,4-butanediol, and the small molecule triol chain extender is trimethylolpropane.

[0044] During use, aromatic isocyanates are used. The isocyanate groups in aromatic isocyanates have high reactivity and can react with polyester polyols, polyether ester polyols and small molecule chain extenders to form a cross-linked structure of polyurethane resin, so that the resin can cure quickly and improve production efficiency. Due to the presence of aromatic structures, the intermolecular forces are strong, so that the resin has good mechanical properties after curing and can withstand certain external forces and pressures. The molecular structure of polyester polyols contains ester bonds, which makes it have strong polarity and can produce good bonding with a variety of substrates, providing excellent bonding properties for the resin, ensuring that the resin can be firmly attached to the surface of the tent, and has certain heat resistance. It can still maintain good performance stability at high temperatures, improving the adaptability of the tent to high temperature weather outdoors. The polyether ester polyols, which are polymerized by polyether and polyester and initiated by double metal cyanide complex catalysts, combine the advantages of polyether and polyester, and have both good hydrolysis resistance brought by polyether segments and certain strength and hardness provided by polyester segments. In wet or In water environment, the resin prepared by polyetherester polyol can maintain good performance, and it is not easy to reduce strength and other properties due to hydrolysis. After being applied to tents, the tents can have good waterproof performance and good air permeability. The presence of polyether chain segments also gives the resin a certain flexibility, so that the resin can undergo a certain degree of deformation when subjected to external force and is not easy to break, thereby improving the impact resistance and toughness of the resin. The small molecule diol chain extender can react with the prepolymer in the resin to extend the molecular chain, thereby increasing the molecular weight of the resin. The increase in molecular weight helps to improve the strength, hardness, viscosity and other properties of the resin. The small molecule triol chain extender has three hydroxyl functional groups. In combination with the small molecule diol chain extender, the strength, hardness, viscosity and other properties of the resin can be further improved. At the same time, the small molecule triol chain extender can improve the toughness of the resin to a certain extent. The three hydroxyl groups in its molecular structure can form a more complex network structure with the resin molecules, so that the resin can better absorb energy when subjected to external force impact, reduce the generation and expansion of cracks, and improve the toughness and impact resistance of the material.

[0045] The remaining structure is the same as that of Example 2.
