Embodiment 1

[0021] A method for making a silicone mold, characterized in that it comprises the following sequential steps:

[0022] (1) wash and dry the master model, and make smooth treatment;

[0023] (2) 500 grams of mold silicone rubber is filled as a plastic basin for subsequent use;

[0024] (3) adding the hardening agent into the container after weighing 1.5% by weight and mixing, fully stirring evenly;

[0025] (4) Add silica gel diluent until it is evenly mixed, and the time is 3 minutes;

[0026] (5) After the mold silicone rubber is mixed with the hardener, it reacts at room temperature and releases low-molecular alcohol. In order to make the alcohol molecules detach from the colloid, it needs to be defoamed under negative pressure for 1-3 minutes. It is also possible without the aid of equipment;

[0027] (6) For the multi-layer coating mold, it is advisable to cure the inside, middle and outside at the same time. When the amount of curing agent is relatively small, the re...

Embodiment 2

[0031] A method for making a silicone mold, characterized in that it comprises the following sequential steps:

[0032] (1) wash and dry the master model, and make smooth treatment;

[0033] (2) 1000 grams of mold silicone rubber is filled as a plastic basin for subsequent use;

[0034] (3) adding the hardening agent into the container after weighing 2.5% by weight and mixing, fully stirring evenly;

[0035] (4) Add silica gel diluent until it is evenly mixed, the time is 5 minutes;

[0036] (5) After the mold silicone rubber is mixed with the hardener, it reacts at room temperature and releases low-molecular alcohol. In order to make the alcohol molecules detach from the colloid, it needs to be defoamed under negative pressure for 1-3 minutes. It is also possible without the aid of equipment;

Embodiment 3

[0041] A method for making a silicone mold, characterized in that it comprises the following sequential steps:

[0042] (1) wash and dry the master model, and make smooth treatment;

[0043] (2) 750 grams of mold silicone rubber is filled as a plastic basin for subsequent use;

[0044] (3) adding the hardening agent into the container after weighing 2% by weight and mixing, fully stirring evenly;

[0045] (4) Add silica gel diluent until the mixture is uniform, the time is 4 minutes;

[0046] (5) After the mold silicone rubber is mixed with the hardener, it reacts at room temperature and releases low-molecular alcohol. In order to make the alcohol molecules detach from the colloid, it needs to be defoamed under negative pressure for 1-3 minutes;

[0047] (6) For the multi-layer coating mold, it is advisable to cure the inside, middle and outside at the same time. When the amount of curing agent is relatively small, the reaction time will be longer, the reaction will be suff...

Abstract

The invention discloses a manufacturing method for a silicone mold. The production technology is simple and perfect in operation, various hardening agents are added during preparation, various reaction time is fully controlled, the silicone mold produced under the optimum conditions has the advantages of high-temperature resistance, corrosion resistance, strong tear resistance, high simulation fineness and the like, and is widely applied to preparation of various handworks.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a method for making a silicone mold. Background technique [0002] Silicone mold is a special mold glue for making handicrafts. Silicone is characterized by high temperature resistance, corrosion resistance, strong tear resistance, and high simulation precision. It is a special mold for making various handicrafts. Silicone kitchenware raw materials can be divided into ordinary silica gel and weather silica gel according to their performance. Ordinary silica gel, also known as precipitated silica gel, is mostly used in middle and low-end silica gel products such as mobile phone buttons, miscellaneous parts, and conductive adhesives. Weather glue is also known as pure silica gel, because this material has good transparency and strong tensile strength, but the cost is high. Used in silicone tubes, protective sleeves and other high-end products that require high elasticity. Silic...
