Abstract
The invention discloses a production process of a PPSU (Polyphenylsulphone) milk bottle. An existing method has the problems that bubbles are easily generated, the qualification rate is relatively low, and the cost is relatively high. The production process comprises the following steps: (1) performing dehumidification drying, namely baking a PPSU raw material; (2) performing glue-smelting, namely performing glue-smelting on the baked PPSU raw material; (3) performing injection moulding, namely injecting molten glue into a bottle mould, and keeping the pressure of 6.0MPA for 2-3 seconds to obtain a bottle blank; (4) performing stretching blowing forming on the bottle blank to obtain the PPSU milk bottle. The PPSU milk bottle produced from PPSU as the raw material is good in chemical resistance, stable in color and size, difficult to colorize by foods, light in weight and low in thermal expansion coefficient, has the advantages of high strength and high transparency, and can keep stable performance at the temperature ranging from -50 DEG C to 220 DEG C; the pressure is maintained in the injection moulding process, so that the occurrence rate of bubbles is effectively reduced, the product qualification rate is increased, and the production cost is reduced.
Description
Technical field
The invention belongs to production and processing technical field, relate in particular to a kind of production technology of PPSU feeding bottle.
Background technology
Feeding bottle in the past adopts Merlon (PC) and epoxy resin to make more, and Merlon (PC) and epoxy resin are synthetic by bisphenol-A, and bisphenol-A can cause endocrinopathy, and infant's health in serious threat.From 2 days March in 2011, forbid producing the baby bottles containing chemical substance bisphenol-A (BPA).Existing market has been developed a kind of taking PPSU(PPSU) make feeding bottle for raw material, this feeding bottle is containing bisphenol-A, and has the penetrating slim and graceful resistance to feature of falling with PP feeding bottle of the safety of glass feeding bottle concurrently.But this feeding bottle, in manufacturing process, is easy to produce bubble, and qualification rate is lower, and cost is higher.
Summary of the invention
The object of this invention is to provide one and can effectively reduce bubble generation, improve the production technology of the PPSU feeding bottle of product percent of pass, and it is high that the feeding bottle of being produced by this manufacture craft has intensity, the advantage that transparency is high, can be stable-50 DEG C to 220 DEG C temperature range retentions.
For achieving the above object, the production technology of PPSU feeding bottle of the present invention comprises the following steps:
(1) removal moisture drying: by PPSU(PPSU) raw material toasts, and baking temperature is 155～165 DEG C, and baking time is 3.5～4.5h;
(2) melten gel: the PPSU raw material of oven dry is carried out to melten gel, and melten gel temperature is 350～380 DEG C;
(3) injection moulding: by fusing glue inject bottle a mould, and under 6.0MPA pressurize 2～3s, make bottle base;
(4) while bottle base being cooled to 130～150 DEG C, bottle base is carried out to stretch blow moulding, obtain described PPSU feeding bottle.
As preferably, described melten gel temperature is 370 DEG C.
As preferably, described stretch blow temperature is 80～100 DEG C.
The present invention, compared with conventional art, has the following advantages:
The PPSU feeding bottle that the present invention produces taking PPSU as raw material, chemical resistance is strong, and colour stable is difficult for by food coloring, and lightweight, and thermal coefficient of expansion is low, can keep the stable of size; Have in addition intensity high, the advantage that transparency is high, can be stable-50 DEG C to 220 DEG C temperature range retentions; Feeding bottle carries out pressurize in injection moulding process can effectively reduce the incidence of bubble, improves the qualification rate of product, and then has reduced production cost.
