To address the problems of brittleness and poor elastic deformation ability of Silicate Cement stone, anionic styrene-butadiene latex particles were prepared using emulsion polymerization with styrene, liquid polybutadiene, 2-acrylamido-2-methyl-1-propanesulfonic acid, and fumaric acid as raw materials. The dispersion properties of anionic styrene-butadiene latex particles in water were investigated, as well as the elastic enhancement effect of the particles in cement. The test results show that anionic styrene-butadiene latex particles have good dispersion performance in water, is not easy to agglomerate, and can improve the fluidity of cement slurry. The elastic modulus of anionic styrene-butadiene latex particles cement stone is 43.1% and 27.8% lower than that of blank cement stone and commercially available latex particles cement stone, respectively. The finding of the mechanism analysis demonstrate that the anionic styrene-butadiene latex particles can be filled in cement stones to increase the silicate cement’s elasticity, compactness, and resistance to external stress.

To address the problems of brittleness and poor elastic deformation ability of oil‐well cement stone, styrene‐butadiene latex powder was prepared using emulsion polymerization with styrene, liquid polybutadiene, 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid, and fumaric acid as raw materials. The dispersion properties of styrene‐butadiene latex powder in water were investigated, as well as the elastic enhancement effect of the powder in cement. The test results showed that styrene‐butadiene latex powder has good dispersion performance in water and is not easy to agglomerate, which can improve the fluidity of cement slurry. The elastic modulus of cement stone mixed with styrene butadiene latex powder is 43.1% and 27.8% lower than that of blank cement stone without styrene‐butadiene latex powder and the cement stone mixed with commercially available latex powder, respectively. The results of the mechanism analysis showed that the styrene‐butadiene latex powder can be filled in the cement stone, improved the compactness of the cement stone, buffered the external stress impact, and improve the elasticity of the cement stone.

“…At the same time, there are many pores inside the cured cement stone, which affects the mechanical properties of the cement stone. In addition, currently only about 5% of styrene‐butadiene latex currently on the market can be used in oil well cement 22–25 . Epoxy resin (EP) is a kind of flexible polymer material, with good temperature resistance and corrosion resistance, high chemical stability, excellent mechanical properties, and high bond strength, can be cured with curing agent to form an elastomer.…”

To solve the problem of high brittleness and easy cracking of cement stone, epoxy resin powder elastic particles (HEEP) were developed to improve the elasticity of cement stone. HEEP was prepared from epoxy resin and trimeric anhydride by solution polymerization. The surface wettability and particle size of HEEP were analyzed by contact angle test and laser particle size analysis respectively. Mechanical performance tests, scanning electron microscope (SEM) analysis and x‐ray diffraction analysis were conducted on the cement stone containing HEEP. The results showed that HEEP was the target product, with a hydrophilic surface and a water contact angle of 75.2° on the HEEP surface. The particle size distribution of HEEP was uniform, and the median particle size was 36.5 μm. The initial decomposition temperature of HEEP was 300°C, indicating a good thermal stability. The stress–strain curve showed that when the HEEP dosage was 3%, 6%, and 9%, the elastic modulus of the cement stone was 6.382, 4.017, and 3.148 GPa, respectively. Compared with the blank cement without HEEP, the elastic modulus was reduced by 28.3%, 54.9%, and 64.6%, respectively. This showed that HEEP could effectively improve the elasticity of cement stone. In addition, the compressive strength and flexural strength of cement stone containing HEEP can meet the requirements of on‐site applications. SEM analysis of cement stone showed that HEEP was well filled in cement stone. When the cement stone was subjected to complex stress, HEEP could effectively buffer and disperse the stress, thereby enhancing the resistance of cement stone to external force impact.
