1、香豆酮

香豆酮-茚树脂是由煤焦油馏分（含香豆酮、茚等组分）经催化聚合制成的热塑性树脂，又称苯并呋喃-茚树脂或古马隆-茚树脂。 该树脂按软化点分为液体（5-35℃）、黏性固体（35-75℃）和脆性固体（75-135℃），外观呈浅黄至黑色黏稠液体或脆性固体，具有耐酸碱、耐水、电绝缘及热塑性特点，可溶于氯代烃、酯类等有机溶剂，但不溶于低级一元醇和多元醇及蓖麻油。 该树脂于1890年由美国人G.克雷默首创，通过氯化铝等催化剂聚合制得，主要用于橡胶软化剂（增强硫黄溶解性及炭黑分散性）、涂料（替代松香）、胶黏剂及塑料增塑剂，并应用于油墨、电池外壳和覆铜板低温脆化胶水制备。 21世纪初成为橡胶行业主导黏结剂，广泛用于轮胎、胶管等制品生产。

Comparison on the performance of solid coumarone

Throughout the experiment, solid coumarone-indene resin modified asphalt (S-CMA) and liquid coumarone-indene resin modified asphalt (L-CMA) are prepared by blending solid coumarone-indene resin (S-CIR) and liquid coumarone-indene resin (L-CIR) into the base asphalt (YZ-70#).

Massive Preparation of Coumarone

In this work, we report the massive preparation of coumarone-indene resin-based hyper-crosslinked polymers via one-step Friedel-Crafts alkylation. Low-cost coumarone-indene resin serves as the new building block and chloroform is employed as both solvent and external crosslinker.

Indene/coumarone resins

Hydrocarbon resins, rosin, rosin ester, coumarone indene resins, and terpene resins can be directly added to solvent-borne adhesives. For latex adhesives, resin emulsification must be produced before addition.

Coumarone-indene resin is a high-molecular-weight compound widely used in the chemical industry, with its primary component being epoxy resin. Due to its excellent physical and chemical properties, it is extensively applied in manufacturing coatings, adhesives, composite materials, and more. with advancements in technology and growing environmental awareness, concerns about the sustainable use of this resin and its environmental impact have emerged.

First, it is essential to understand the basic properties of coumarone-indene resin. It is a thermosetting resin that requires high-temperature reactions with curing agents to form a solid coating. This process demands significant energy input, resulting in substantial heat generation. Additionally, harmful substances in the resin can adversely affect the environment and human health.

So, can coumarone-indene resin be mixed with water? The answer is affirmative. In fact, many individuals have begun experimenting with blending the resin with water to mitigate its environmental impact.

Firstly, water’s solubility can reduce the resin’s viscosity. By adding a specific proportion of water, the resin’s viscosity decreases significantly, making it easier to apply and work with. This not only enhances construction efficiency but also reduces energy consumption and material waste.

Secondly, water’s volatility can minimize the resin’s irritating odor. Since the resin contains volatile organic compounds (VOCs) such as toluene and benzene, which emit strong smells, incorporating water lowers the concentration of these substances, thereby reducing harm to humans.

Furthermore, water’s diluting effect can decrease the resin’s toxicity. Harmful components like formaldehyde and phenol, present in the resin, are toxic. Adding water dilutes these substances, reducing their concentrations and mitigating health risks.

it is crucial to note that while mixing the resin with water can lower environmental impacts, it does not mean water can fully replace the resin. In certain applications, coumarone-indene resin remains indispensable. For instance, in construction, it is used as an additive in concrete to enhance strength and durability. In such cases, simply substituting water for the resin is not viable.

economic costs and practicality must be considered. While blending the resin with water improves efficiency and eco-friendliness, it also requires additional time and resources for processing the mixture. Additionally, the resin’s reactivity with water may affect its compatibility with other materials, compromising the quality and performance of the final product.

while mixing coumarone-indene resin with water is a feasible approach, its applicability depends on specific scenarios and requirements. Decisions should balance environmental benefits, economic viability, and practical utility to achieve sustainable development and maximize the resin’s effectiveness.
