【摘要】：橡膠膏劑有溶劑法和熱壓法2種制備方法。溶劑法生產(chǎn)的產(chǎn)品黏性好、皮膚殘留物少,但生產(chǎn)過程使用了溶媒,存在安全隱患和環(huán)境污染等問題;熱壓法生產(chǎn)橡膠膏劑,取消了溶媒,安全、環(huán)保、占地面積小、成本低、揮發(fā)性藥物損失少、老化慢、生產(chǎn)周期短、生產(chǎn)效率高,熱壓法代替溶劑法生產(chǎn)橡膠膏劑是發(fā)展趨勢。橡膠膏劑的涂膠工藝分為直涂法和反涂法2種,直涂法對布匹要求高,生產(chǎn)時膠面容易產(chǎn)生黏連等問題;反涂法操作簡單、含膏量穩(wěn)定、生產(chǎn)效率高,可應(yīng)用四面彈性布做襯材。降低橡膠基質(zhì)軟化溫度并且保證其耐熱性能是實現(xiàn)反涂熱壓法生產(chǎn)橡膠膏劑的關(guān)鍵,調(diào)整基質(zhì)中軟化劑、增粘劑、橡膠等用量比例,能夠?qū)崿F(xiàn)熱壓法產(chǎn)品在光澤度、初粘性、持粘性、內(nèi)聚力等方面與溶劑法相似。
[Abstract]:Rubber paste has two preparation methods: solvent method and hot pressing method. The products produced by the solvent method have good viscosity and less skin residue, but the production process uses solvent, which has some problems such as safety hidden trouble and environmental pollution, etc. The hot pressing method produces rubber paste, which cancels the solvent, is safe, is environmentally friendly, occupies small area, and has low cost. The volatile drugs lose little, aging slowly, production cycle is short, production efficiency is high, hot pressing method instead of solvent method to produce rubber paste is the development trend. The rubber paste coating process is divided into two kinds: direct coating method and reverse coating method. The direct coating method has high requirements on cloth, and the adhesive surface is easy to be glued in production, and the reverse coating method is simple in operation, stable in paste content and high in production efficiency. Four-sided elastic cloth can be used as lining material. Reducing the softening temperature of rubber matrix and ensuring its heat resistance is the key to the production of rubber paste by reverse coating hot pressing. Adjusting the proportion of softener, tackifier and rubber in the matrix can realize the gloss and initial viscosity of the hot pressing product. Viscosity, cohesion and other aspects are similar to solvent method.
