Abstract

The invention relates to a high-accuracy dental alginate impression material applying nanoscale raw materials and a preparation method of the alginate impression material, relates to the field of impression materials and solves the problems that existing alginate impression materials adopting a filler-diatomite-talc powder structure have poor fineness, lower compressive strength, low deformation recovery rate, high probability of deformation after curing and difficulty in keeping size stability. The high-accuracy dental alginate impression material is prepared from components in parts by weight as follows: 10-18 parts of alginate, 8-15 parts of gypsum, 3-7 parts of sodium pyrophosphate, 1-3 parts of potassium fluotitanate, 8-15 parts of magnesium oxide, 45-60 parts of nanoscale diatomite,5-15 parts of nanoscale talc powder and 3-5 parts of white oil. The effects of improving the fineness of gel, improving the compressive strength and improving the deformation recovery rate are achieved by means of special uniformity and stability of raw materials including nanoscale filler diatomite and nanoscale talc powder, and the size stability of the cured gel is improved.

Description

technical field [0001] The invention relates to the technical field of impression materials, in particular to a high-precision dental alginate impression material using nano-scale raw materials and a preparation method thereof. Background technique [0002] Alginate impression material is a kind of uniform impurity-free powder, which can form a uniform, non-agglomerated, non-granulated and smooth plastic body after adding water, which is used to make various impressions, such as teeth or oral tissue, human body Turn over the mold and so on. [0003] The traditional filler-diatomaceous earth-talcum powder has an uneven structure, a large particle size distribution range and poor consistency, which results in insufficient fineness of the alginate impression material product, and the gel has water loss shrinkage and water absorption swelling after curing. problems, resulting in poor dimensional stability; in practical applications, it is necessary to pour gypsum as soon as pos...
