Embodiment 1

[0030] The potassium-barium glass is produced as a lens product used in automobile lamps through the following preparation process, which specifically includes the following steps:

[0031] S1, batching: take the following components by weight, then put it into a mixing machine to make batches,

[0032]

[0033] S2. Melting: Mix the batch material with recycled glass, put a total of about 451kg into the melting furnace, keep it warm at about 1500°C for about 60 hours, and then pass through the roaring and ascending roads to obtain clear molten glass. The melting furnace is heated by electricity ;

[0034] S3, forming: the glass liquid is injected into the mould, and is molded by a dropping machine;

[0035] S4, annealing: the formed product is annealed in the following stages: the first stage of cooling annealing, the second stage of heat preservation, the third stage of cooling annealing and the fourth stage of natural cooling, and after being cooled to room temperature, ...

Abstract

The invention belongs to optical glass, and particularly relates to potassium-barium glass for a lens, and a preparation method and application thereof. Production raw materials of the potassium-barium glass for the lens comprise silicon dioxide, potassium carbonate, barium carbonate and sodium carbonate, and the weight percentage content of the sodium carbonate is 2% or below; the total weight percentage of the potassium carbonate and the barium carbonate is 12-18%; and the weight ratio of the potassium carbonate to the barium carbonate is (6-9): 1. The preparation method comprises the steps of burdening, melting, forming and annealing. According to the technical scheme provided by the invention, potassium carbonate and barium carbonate are used for replacing part of sodium carbonate in soda-lime glass, so that the content of sodium carbonate in the formula is reduced, and the problem of acid spitting of the lens is solved; and all the components have a synergistic effect and are matched with a proper processing technology, so the comprehensive performance requirement of the lens for an automobile lamp is met.

Description

technical field [0001] The invention belongs to the technical field of optical glass, in particular lens glass for vehicle lamps, and specifically relates to a potassium-barium glass used for lenses and its preparation method and application. Background technique [0002] Car lights generally include LED lights, lenses and lampshades set in front of the LED lights. Compared with headlights using traditional lamp caps, headlights with lens caps have uniform brightness and strong penetrating power. Weather has strong penetrating power. [0003] The existing lens glass material is mainly soda-lime glass. After the glass lens is exposed to light for a long time, if it meets the need for car cleaning or encounters rainy weather, the soda-lime glass lens will spit out acid when it is exposed to high temperature and high heat for a long time. , that is, white particles will be precipitated, which will affect the light transmittance of the glass and cause driving hazards. [0004]...
