The present invention will be further illustrated with reference to the following specific examples.

The invention comprises the following components in parts by weight:

natural latex: 100 parts of (A);

vulcanizing agent: 1-8 parts;

potassium oleate: 0-1.5 parts;

potassium ricinoleate: 0-1 part;

A processing technology of a latex mattress containing emblic leafflower fruit kernel oil comprises the following steps:

s1, blending and ripening; the raw materials (namely the components above) are prepared according to the formula and stirred uniformly, and then stirred for 0.5-1h, and pre-vulcanized;

s2, foaming: injecting the mixed latex into a mould for foaming;

s3, vulcanization: after foaming, the latex enters a steam box for vulcanization;

s4, washing and drying: drying by using radio frequency equipment, and then drying by using a blast oven.

In the step S1, the temperature of the prevulcanization latex is 25-30 ℃, and the prevulcanization time is 9-15 h.

In the step S3, the vulcanizing time is 15min-30min, and the temperature of the steam box is 95-100 ℃.

In the step S4, drying by using radio frequency equipment, wherein the radio frequency heating power is 30-60kW, and the time is 10-15 min; then drying in a blast oven at 80-130 deg.C for 15-30 min.

The emblic leafflower fruit kernel oil contains rich fatty acid, mainly comprises linolenic acid, linoleic acid, oleic acid, palmitic acid, stearic acid and the like, and the saponification liquid is used for latex foaming, so that not only is the resource fully utilized, but also the addition amount of small materials (namely potassium oleate and potassium ricinoleate) is reduced to a certain extent, and the latex content in the latex sponge is improved.

The processing process of the phyllanthus emblica kernel oil saponification liquid comprises the following steps: weighing 10kg of emblic leafflower fruit kernel oil, adding the emblic leafflower fruit kernel oil into 36L of potassium hydroxide solution with the concentration of 1mol/L, stirring and reacting for 2h at the temperature of 85 ℃, and completely cooling to room temperature to obtain saponified solution.

Between the steps S1 and S2, the method also comprises the steps of preparing the lac resin calcium salt aggregate, and introducing the lac resin calcium salt aggregate into the mixed latex for stirring;

wherein the preparation process of the lac resin calcium salt aggregate comprises the following steps: the lac resin sodium salt is prepared into 6wt% lac resin sodium salt solution (namely, the lac resin sodium salt is dissolved in water), and 0.1mol/L CaCl is prepared by distilled water₂Slowly stirring the solution at 20 deg.C, and slowly adding CaCl₂Mixing the solution, stirring for 20min, standing at room temperature for 6h, filtering to obtain precipitated solid, and freeze drying to obtain lac resin calcium salt aggregate;

introducing lac resin calcium salt aggregate into mixed latex before foaming, wherein the lac resin sodium salt is in a quasi-asymmetric Gemini (Gemini) surfactant structure, and Ca is added²⁺The lac resin is composed of lactone and lactide formed from lac eleostearic acid and chitonic acid, and the lac eleostearic acid is a straight-chain macromolecule and contains polyhydroxy saturated carbon chain, so that a large quantity of hydroxyl groups are present on the surface of the lac resin calcium salt, and is beneficial to organic compounds (such as lac resin calcium salt) through hydrogen bonding effectAlcohols, amines, etc.).

Therefore, the produced mattress meets the requirements of low odor, low VOC and environmental protection.

And between the steps S2 and S3, hot air shaping is further included, and shaping is carried out in a mode of mixing carbon dioxide and hot air.

Before hot air shaping, the surface of the foaming latex is preliminarily gelled, the foaming latex has certain strength, carbon dioxide enters the foaming latex along with hot air permeation to be combined with moisture in the foaming latex to form carbonic acid, ammonia carbonate is formed with ammonia in natural latex, the pH is reduced, the foaming latex can be gelled in an accelerated mode, and therefore the foaming latex can be fully gelled in the foaming latex before entering a vulcanization stage. Therefore, the production efficiency can be improved and the cost can be reduced on the premise of not influencing the product quality. Thereby avoiding the phenomenon that the foaming latex is not completely gelled before entering the vulcanization stage and the foam collapses in the vulcanization stage.
